ABSTRACT
Nanoparticles (NPs) are insoluble particles with a diameter of fewer than 100 nanometers. Two main methods have been utilized in orthodontic therapy to avoid microbial adherence or enamel demineralization. Certain NPs are included in orthodontic adhesives or acrylic resins (fluorohydroxyapatite, fluorapatite, hydroxyapatite, SiO2, TiO2, silver, nanofillers), and NPs (i.e., a thin layer of nitrogen-doped TiO2 on the bracket surfaces) are coated on the surfaces of orthodontic equipment. Although using NPs in orthodontics may open up modern facilities, prior research looked at antibacterial or physical characteristics for a limited period of time, ranging from one day to several weeks, and the limits of in vitro studies must be understood. The long-term effectiveness of nanotechnology-based orthodontic materials has not yet been conclusively confirmed and needs further study, as well as potential safety concerns (toxic effects) associated with NP size.

ABSTRACT Objective: This study aims to examine the risk perceptions of midwifery and nursing senior students regarding COVID-19 and compliance with vaccination and protective measures. Method: This cross-sectional study was conducted in two academic years on senior midwifery and nursing students (n = 358). In the present study, the descriptive characteristics of the students and the COVID-19 risk perception scale were used. Results: The students' COVID-19 Risk Perception Scale scores were at a moderate level and a similar level in both years of this study. More than 80% of the students were fully vaccinated, and the family history of COVID-19 was positive in approximately half of them. In the second year of the pandemic, they paid less attention to social distance and avoidance of being indoors. Conclusion: Although the COVID-19 risk perceptions of future health professional students remained at a similar level during the examined period, it was found that in the second year of the pandemic, they started to get used to the process and paid less attention to social protective measures.
RESUMO Objetivo: Este estudo tem como objetivo examinar as percepções de risco de estudantes sêniores de obstetrícia e enfermagem em relação à COVID-19 e o cumprimento das medidas de vacinação e proteção. Método: Este estudo transversal foi realizado ao longo de dois anos acadêmicos com estudantes sêniores de obstetrícia e enfermagem (n = 358). No presente estudo, foram utilizadas as características descritivas dos estudantes e a escala de percepção de risco da COVID-19. Resultados: As pontuações dos estudantes na Escala de Percepção de Risco da COVID-19 situaram-se num nível moderado e semelhante em ambos os anos do estudo. Mais de 80% dos estudantes estavam totalmente vacinados, e aproximadamente metade deles tinha histórico familiar de COVID-19. No segundo ano da pandemia, prestaram menos atenção ao distanciamento social e aos hábitos de evitar permanência em espaços fechados. Conclusão: Embora as percepções de risco da COVID-19 dos futuros profissionais de saúde tenham permanecido em níveis semelhantes durante o período examinado, verificou-se que, no segundo ano da pandemia, começaram a acostumar-se com o processo e prestaram menos atenção às medidas de proteção social.

ABSTRACT
Background Polycyclic aromatic hydrocarbons (PAHs), one of the main components of fine particulate matter (PM2.5), have a certain impact on ambient air quality, and long-term exposure to PAHs may pose potential health risks to human beings. Objective To identify the distribution characteristics and sources of PAHs in atmospheric PM2.5 in a district of Taizhou City from 2019 to 2021, and to evaluate the health risks of PAHs to the population in the area through the inhalation pathway. Methods From 2019 to 2021, air PM2.5 sampling was carried out at a state-controlled surveillance point in a district of Taizhou City for 7 consecutive days on the 10th-16th of each month, the sampling time was 24 h·d−1, and the sampling flow rate was 100 L·min−1. PM2.5 mass concentration was calculated by gravimetric method. A total of 16 PAHs were determined by ultrasonic extraction-liquid chromatography. Kruskal-Wallis H test was used to compare the distribution charac teristics of PAHs concentrations by years and seasons, characteristic ratio and principal component analysis (PCA) was used to analyze their sources, and a lifetime carcinogenic risk (ILCR) model was used to assess the health risk of PAHs. Results From 2019 to 2021, the annual average concentrations [M (P25, P75)] of ∑PAHs in atmospheric PM2.5 in the selected district of Taizhou City were 6.52 (2.46, 10.59), 8.52 (4.56, 12.29), and 3.72 (1.51, 7.11) ng·m−3, respectively, and the annual benzo[a]pyrene (BaP) excess rates (national limit: 1 ng·m−3) were 27.38% (23/84), 47.62% (40/84), and 19.04% (16/84), respectively, both presenting 2020> 2019 > 2021 (P<0.001, P<0.05). The ∑PAHs concentration distribution showed a seasonal variation, with the highest value in winter and the lowest value in summer (P<0.05). Among the atmospheric PM2.5 samples, the proportion of 5-ring PAHs was the highest, the proportion of 2-3-ring PAHs was the lowest; the proportion of 2-4-ring PAHs showed a yearly upward trend, and the proportion of 5-6-ring PAHs showed yearly downward trend (P<0.05). The characteristic ratio and PCA results suggested that the sources of sampled PAHs were mainly mixed sources such as dust, fossil fuel (natural gas), coal combustion, industrial emissions, and motor vehicle exhaust emissions. The ILCR (RILCR) of PAHs by inhalation for men, women, and children were 1.83×10−6, 2.35×10−6, and 2.04×10−6, respectively, and the annual average RILCR was 2.07×10−6, all greater than 1×10−6. Conclusion For the sampled time period, the main sources of PAHs pollution in atmospheric PM2.5 in the target district of Taizhou City are dust, fossil fuel (natural gas), coal combustion, industrial emissions, motor vehicle emissions, etc., and PAHs may have a potential carcinogenic risk to local residents.
ABSTRACT
Abstract In Brazil, the advent of voluntary and counseling testing (VCT) has provided many benefits in the fight against AIDS. A sectional open web survey was conducted to investigate the Brazilian LGBT+ individuals' knowledge and perceptions of the existence of VCT centers and their associations with risk behavior and other variables of interest. The study instrument included questions on sociodemographic and behavioral variables, knowledge on VCT, access to and use of it, beliefs about HIV infection, test results, and risk perception. The Risk Behavior Score for HIV infection (RBS) was also used. A total of 1,630 volunteers participated in the survey, of whom 56.8% were men. Of these, 96.1% declared themselves as (MSM). Almost 50% of the participants had never heard about the existence of VCT, which was a higher knowledge score among MSM. A low frequency of participants had a clear perception of the risks to which they are exposed, whereas those with higher RBS were aware of the existence of VCT. As VCT is critical for the implementation of policies to combat and prevent HIV and other sexually transmitted diseases, our results can contribute to a better understanding of the influence of VCT on the frequency of testing, serological surveillance, and routine counseling for key populations.
Resumo No Brasil, o advento dos centros de testagem e aconselhamento (CTA) trouxe muitos benefícios na luta contra a Aids. Um estudo transversal do tipo web survey foi realizado para investigar o conhecimento e as percepções dos indivíduos LGBT+ brasileiros sobre a existência dos CTAs e suas associações com comportamentos de risco e outras variáveis de interesse. O questionário incluiu questões sociodemográficas e comportamentais, conhecimento sobre o CTA, acesso e uso, crenças sobre a infecção pelo HIV, resultados de testes e percepção de risco. O escore de comportamento de risco (RBS) também foi utilizado. Participaram 1.630 voluntários (56,8% homens). Destes, 96,1% se autodeclararam homens que fazem sexo com homens (HSH). Quase 50% dos participantes não conhecem os CTAs, sendo este conhecimento maior entre os HSHs. Uma baixa frequência de participantes tem percepção clara dos riscos a que estão expostos, e os HSHs com maior pontuação no RBS estão cientes da existência dos CTAs, que são fundamentais na implementação de políticas de combate e prevenção ao HIV e outras doenças sexualmente transmissíveis. Nossos resultados contribuem para a melhor compreensão da sua influência na frequência de testagem, na vigilância do status sorológico e no aconselhamento em populações-chave.
ABSTRACT
Introducción: La conducta suicida es la causa de la mitad de las muertes violentas. Se considera un problema de salud pública con un millón de víctimas al año. El intento de suicidio es el factor de riesgo más importante. En Colombia, en 2017 la tasa de intento de suicidio fue de 51,8/100.000 hab. y la letalidad alcanzó 10,0/100.000. El objetivo es identificar factores del intento suicida asociados con la muerte y determinar la supervivencia después del intento durante 2 años. Material y métodos: Estudio de cohorte retrospectiva y análisis de supervivencia. Se cruzaron 42.594 registros del sistema de vigilancia de intento de suicidio con 325 muertes por suicidio del registro único de defunciones de 2016 y 2017. Se examinaron factores de riesgo, y se realizó la prueba de la x2, análisis multivariado y regresión logística. Se calculó la probabilidad de supervivencia acumulada con el método de Kaplan-Meier. Se aplicó un modelo de regresión de Cox para determinar la relación proporcional de las variables del intento suicida que se relacionan con suicidio. Resultados: Por cada muerte de mujer por suicidio, mueren 4,5 varones por esta causa; 1 de cada 4 personas fallecidas reportó al menos un intento previo. Los factores del intento relacionados con la muerte por suicidio fueron: ser varón (HR = 2,99; IC95%, 2,27-3,92), la edad adulta (> 29 años, HR = 2,38; IC95%, 1,90-2,99), vivir en área rural (HR = 2,56; IC95%, 2,04-3,20) y padecer enfermedad crónica (HR = 2,43; IC95%, 1,66-3,57) o trastorno depresivo (HR = 1,94; IC95%, 1,55-2,41). El 50% de las muertes por suicidio ocurren hasta en los 560 días posteriores al intento. Conclusiones: Se evidencia mayor riesgo de suicidio en pacientes varones, con historia de expresión, antecedentes de enfermedades crónicas y exposición a carga laboral.
Background: Suicidal behaviour is the cause of half of all violent deaths. It is considered to be a public health problem with one million victims a year. Suicide attempt is the most important risk factor. In Colombia, in 2017 the suicide attempt rate was 51.8/100,000 inhabitants, and he fatality rate reached 10.0/100,000. The objective is to identify suicide attempt factors associated with death and determine survival after the attempt for 2 years. Material and methods: Retrospective cohort study and survival analysis. A total of 42,594 records of the suicide attempt surveillance system databases and 325 records of death by suicide in 2016 and 2017 were analysed. The risk factors were examined and a X2-test and multivariate analysis and logistic regression were performed. Cumulative survival probability was calculated using the Kaplan-Meier method. A Cox regression model was applied to determine the proportional relationship of the suicide attempt variables that are related to suicide. Results: Men die by suicide 4.5 times more often than women. One in four suicide victims had made at least one prior suicide attempt. The attempt factors related with death by suicide were: male gender (HR = 2.99; 95% CI, 2.27-3.92), adulthood (over 29 years, HR = 2.38; 95% CI, 1.90-2.99), living in a rural area (HR = 2.56; 95% CI, 2.04-3.20), chronic disease history (HR = 2.43; 95% CI, 1.66-3.57) and depression disorder (HR = 1.94; 95% CI, 1.55-2.41). Some 50% of suicide deaths occur up to 560 days after the suicide attempt. Conclusions: The risk of suicide is highest in male patients, with a history of depression, chronic illness and exposure to heavy workloads.
ABSTRACT
Fundamento: la infección por el virus de la inmunodeficiencia humana es una de las infecciones de trasmisión sexual más importantes para la salud a nivel mundial y una de las más temibles del presente siglo. Objetivo: caracterizar la infección por el virus de la inmunodeficiencia humana en personas de 50 años y más. Métodos: se realizó una investigación observacional descriptiva de corte transversal, que incluyó todas las personas diagnosticadas con el virus de la inmunodeficiencia humana, en Cienfuegos, en el período comprendido de 1986 a 2021. Las variables analizadas fueron: edad, sexo, orientación sexual, grupo de pesquisa, diagnósticos por año y municipio de residencia. Resultados: las personas en el grupo de edad de 50 a 59 años aportaron la mayor incidencia con un 75, 21 %; la orientación sexual predominante fue la homosexual (58,9 %); según los grupos de pesquisa, en los tres grupos de edades sobresale el grupo captado con un 41,88 %. En la provincia se observó un incremento mantenido, fundamentalmente en el sexo masculino, en ascenso en los últimos años. Conclusiones: el aumento de los pacientes con 50 años y más, diagnosticados con virus de la inmunodeficiencia humana, indica que es preciso abordar la problemática con un enfoque clínico epidemiológico diferente. Estas características incrementan el riesgo de infección por VIH por lo que deben ser monitorizadas con la aplicación de la Línea de Trabajo 50 y +, del MINSAP. Es necesario realizar actividades dirigidas a disminuir el riesgo.

Objectives: The objective of this study was to investigate the prevalence of the following risk behaviors: experimentation with cigarettes, electronic cigarettes, alcohol, substances, delinquent behavior, and sex at age 15, stratified by sex and socioeconomic position. We also investigated the prevalence of cigarette and alcohol experimentation at age 11 and the persistence and cumulative incidence of these behaviors between 11 and 15 years of age. Methods: In this cohort study, we included 3,491 11-year-olds and 1,949 15-year-olds from the 2004 Pelotas Birth Cohort. All outcomes were identified via confidential questionnaires and were analyzed as binary variables. Results: At age 11, there was a higher prevalence of cigarette experimentation among boys. At age 15, there was a higher prevalence of experimentation with alcohol, cigarettes, and substances among girls; experimentation with cigarettes and sex were more prevalent among those in a low socioeconomic position. We found a high cumulative incidence of alcohol experimentation, as well as persistent alcohol experimentation, in both boys and girls. Conclusions: Further research should clarify causal paths of the high prevalence of risk behaviors during adolescence and its increase among girls.

Introdução: O câncer de pele é o câncer mais prevalente no Brasil, principalmente na Região Sul. Apesar da alta prevalência, é uma comorbidade potencialmente prevenível com medidas de fotoproteção. Objetivo: Analisar os hábitos de proteção solar em pacientes no âmbito da atenção primária. Métodos: Trata-se de um estudo transversal, com abordagem quantitativa e fins analítico-descritivos, com uma amostra de 374 pacientes acima de 18 anos selecionados de uma Unidade Básica de Saúde na Região Sul do Brasil. Como instrumentos, foram utilizados o questionário Sun Exposure Protection Index e um questionário sociodemográfico formulado para este estudo. Resultados: Verificou-se que grande parcela dos entrevistados está em alto risco com relação à exposição solar. Praticamente metade não utiliza protetor solar e a maioria não adota métodos de barreira física para se proteger do sol. O risco decorrente da exposição ao sol foi maior em homens (p=0,007), em pessoas com tonalidade de pele mais escura (p=0,033) e em indivíduos com menor escolaridade (p=0,037). A propensão a melhorar os hábitos de fotoproteção foi menor em pessoas com pele de tonalidade mais escura (p=0,010) e em indivíduos com menor escolaridade (p=0,019). De forma geral, verificou-se que, quanto maior é o risco do indivíduo, pior é a propensão a diminuí-lo com medidas de fotoproteção (p<0,001). Conclusões: Grande parcela dos entrevistados está em alto risco com relação à exposição solar. Cabe aos profissionais de saúde promover a conscientização sobre os riscos da exposiçaÌo inadvertida ao sol e orientar sobre condutas saudaÌveis em fotoproteçaÌo.

Métodos: Se trata de un estudio transversal, con abordaje cuantitativo y fines analítico-descriptivos, con una muestra de 374 pacientes mayores de 18 años, seleccionados de una Unidad Básica de Salud de la región sur de Brasil. Se utilizaron como instrumentos el cuestionario Índice de Protección contra la Exposición Solar y un cuestionario sociodemográfico formulado para este estudio. Resultados: Se encontró que una gran parte de los encuestados se encuentran en alto riesgo con relación a la exposición solar. Casi la mitad no usa protector solar y la mayoría no usa métodos de barrera física para protegerse del sol. El riesgo derivado de la exposición solar fue mayor en hombres (p=0,007), en personas con tono de piel más oscuro (p=0,033) y en personas con menor educación (p=0,037). La propensión a mejorar los hábitos de fotoprotección fue menor en las personas con tono de piel más oscuro (p=0,010) y en las personas con menor educación (p=0,019). En general, se encontró que a mayor riesgo del individuo, peor propensión a reducirlo con medidas de fotoprotección (p<0,001). Conclusiones: Una gran parte de los encuestados se encuentran en alto riesgo con relación a la exposición solar. Corresponde a los profesionales de la salud promover la concienciación sobre los riesgos de la exposición involuntaria al sol y orientar conductas saludables en fotoprotección.

Despite its high prevalence, it is a potentially preventable comorbidity with sun protection measures. Objective: To analyze photoprotection habits in patients in primary care. Methods: This was a cross-sectional study, with a quantitative approach and analytical-descriptive purposes, with a sample of 374 patients over 18 years old, selected from a primary health unit in the South region of Brazil. As instruments, the Sun Exposure Protection Index questionnaire and a sociodemographic questionnaire formulated for this study were used. Results: It was found that a large portion of patients are at high risk in relation to sun exposure. Nearly half do not use sunscreen, and most do not use physical barrier methods to protect themselves from the sun. The risk resulting from sun exposure was higher in men (p=0.007), in people with darker skin tone (p=0.033) and in individuals with less education (p=0.037). The propensity to improve photoprotection habits was lower in people with darker skin (p=0.010) and in individuals with less education (p=0.019). In general, it was found that the greater the risk of the individual, the worse the propensity to reduce it with photoprotection measures (p<0.001). Conclusions: A large portion of patients are at high risk in relation to sun exposure. It is up to health professionals to promote awareness of the risks of inadvertent exposure to the sun and guide healthy behaviors in photoprotection.

Objective: To estimate the prevalence of simultaneity of obesity, hypertension and/or diabetes and the association with sociodemographic and lifestyle-related behavior variables. Methods: This is a cross-sectional study with data from the 2013 National Health Survey. The presence of two/three diseases (obesity, hypertension, and diabetes) was considered multimorbidity of noncommunicable diseases (NCDs). Proportional odds logistic regression model, stratified by sex, was used to assess the sociodemographic and lifestyle factors associated with multimorbidity of NCDs, considering the sample complexity and sample weights. Results: The prevalence of multimorbidity of NCDs was 9.6%. The odds of multimorbidity are higher with increasing age, among blacks, but lower in the north region when compared with other regions of the country for both sexes. The odds of multimorbidity of NDCs increased among women who had lower levels of education and spent more time TV watching, and among men who lived with a partner and did not practice the recommended leisure-time physical activity. Conclusion: Sociodemographic factors and lifestyle-related behaviors were associated with the presence of obesity, hypertension, and/or diabetes.
Objetivo: Estimar la prevalencia de simultaneidad de obesidad, hipertensión y/o diabetes y la asociación con variables sociodemográficas y relacionadas con el estilo de vida. Métodos: Los datos fueron obtenido en la Encuesta Nacional de Salud Brasileña, una encuesta a nivel nacional, realizada en los hogares brasileños y llevada a cabo en 2013. La presencia de dos /tres enfermedades (obesidad, hipertensión y diabetes) se consideró multimorbilidad de las enfermedades no transmisibles (ENT). El modelo de regresión logística de probabilidades proporcionales, estratificado por sexo, se utilizó para evaluar los factores sociodemográficos y de estilo de vida asociados con la multimorbilidad de las ENT, considerando la complejidad de la muestra y los pesos de la muestra. Resultados: La prevalencia de multimorbilidad de las ENT fue del 9,6%. Las probabilidades de multimorbilidad son más altas con el aumento de la edad, entre los negros, pero más bajas en la región norte en comparación con otras regiones del país para los dos sexos. Las probabilidades de multimorbilidad de las ENT aumentaron entre las mujeres que tenían niveles más bajos de educación y pasaban más tiempo viendo la televisión, y entre los hombres que vivían con una pareja y no practicaban la actividad física recomendada para el tiempo libre. Conclusión: Los factores sociodemográficos y los comportamientos relacionados con el estilo de vida se asociaron con la presencia de obesidad, hipertensión y/o diabetes.
ABSTRACT
Objetivo: estimar a prevalência e fatores associados ao uso do preservativo em população ribeirinha. Materiais e método: estudo transversal, analítico, realizado com 209 ribeirinhos do estado da Paraíba, Brasil, de junho a outubro de 2019. Os dados foram coletados por meio de entrevista individual e privativa com a utilização de um questionário estruturado com variáveis sociodemográficas e de comportamento sexual. As análises foram realizadas pela regressão de Poisson e estimadas as razões de prevalência. Análises bivariadas e múltiplas foram utilizadas para identificar associação entre as variáveis sociodemográficas e comportamentais com o uso do preservativo. Resultados: a prevalência estimada de uso do preservativo foi de 18,2% (IC: 95% 13,0-23,4). Ribeirinhos com idade maior que 40 anos apresentaram menor probabilidade de uso do preservativo (RP = 0,53; IC: 95% 0,34-0,83). Por sua vez, ribeirinhos com mais de oito anos de estudo apresentaram maior probabilidade de uso do preservativo (RP = 3,94; IC 95% 2,65-5,88).Conclusões: a prevalência do uso do preservativo entre os ribeirinhos foi baixa. Entretanto, indivíduos com maior escolaridade apresentaram maiores chances de uso. A prevenção combinada é uma alternativa para o controle das infecções transmissíveis, sendo o preservativo a principal medida de prevenção; portanto, compreender as singu-laridades da população ribeirinha e os fatores de risco para a boa adesão é imprescindível

Objective: To estimate the prevalence and factors associated with condom use in a riverside population. Materials and method: Cross-sectional and analytical study with 209 riverside inhabitants in the state of Paraíba, Brazil, from June to October 2019. Data were collected through individual and private interviews using a structured questionnaire with sociodemographic and sexual behavior-related variables. Analysis was conducted using Poisson regression. Prevalence ratios were estimated. Bivariate and multiple analyzes were used to identify the association between sociodemographic and behavioral variables with condom use. Results: The estimated prevalence of condom use was 18.2% (95% CI: 13.0-23.4). Riverside people over 40 years were less likely to use condoms (PR = 0.53; 95% ci: 0.34-0.83). On the other hand, individuals with more than 8 years of schooling were more likely to use condoms (PR = 3.94; 95% CI: 2.65-5.88). Conclusions: The prevalence of condom use among participants was low. However, individuals with higher education attainment were more likely to use it. Combined prevention is an alternative to control communicable infections, with condoms being the main prevention measure. Consequently, understanding the singularities of similar populations and the risk factors for good adherence to condom use is essential.

Objective To investigate the content of thorium (Th) in surface water in Sichuan Province, China, and to evaluate Th-associated health risk via water intake for residents. Methods Twenty-three monitoring sections were set in main surface water bodies in Sichuan Province. From 2016 to 2021, the Th radioactivity level in the water bodies was measured during dry and normal-water seasons. The health risk of residents was evaluated by calculating radioactive Th intake from the surface water bodies combined with the use of a health risk assessment model. Results The Th radioactivity level of the surface water bodies in Sichuan Province was 0.02-0.67 μ./L. There was no significant difference in the Th radioactivity level of different years or different surface water bodies (P > 0.05). A significant difference was observed in the Th radioactivity level of different water seasons (P < 0.05). The total mean annual committed effective doses of Th in all age groups caused by drinking water and water immersion ranged from 3.14 × 10−8 to 8.75 × 10−7 Sv, all lower than the World Health Organization (WHO)-recommended reference level of 0.1 mSv. The overall carcinogenic risks for residents in all age groups ranged from 3.93 × 10−10 to 1.09 × 10−8, all below the most rigorous control limits issued by WHO and International Commission on Radiological Protection. Conclusion The Th-associated health risk via direct water intake and water immersion in main surface water bodies of Sichuan Province is at an acceptable level. Th in main surface water bodies of Sichuan Province is safe for all age groups.
ABSTRACT
Background Exposure to heavy metals has potential adverse impacts on human health, and the concentration of heavy metals in abandoned mining areas may still be higher than that in general areas, so the health risk assessment in such areas cannot be ignored. Objective To explore the health risk of heavy metal exposure and the spatial distribution characteristics of associated main metals in a typical abandoned mining area. Methods Environmental samples of irrigated soil, rice, and drinking water were collected from 13 natural villages under the jurisdiction of a township in Liuzhou, Guangxi from November to December 2019, where a typical abandoned mining was located. Finally, 13 irrigation soil samples, 11 rice samples, and 13 drinking water samples were collected. The concentrations of six metals and metalloid elements in each environmental sample were detected by inductively coupled-plasma mass spectrometry (ICP-MS), including cadmium (Cd), arsenic (As), lead (Pb), chromium (Cr), copper (Cu), and zinc (Zn). At the same time, 251 local residents were recruited for health risk assessment. Model parameters such as body weight, rice intake, and drinking water intake of local residents were obtained through field survey, and the median metal concentration of each environmental sample was taken as the risk assessment parameter of the region. The health risk of heavy metal exposure of local residents was assessed by using oral health risk assessment model of U.S. Environmental Protection Agency. The spatial distribution characteristics of health risks associated with heavy metals were evaluated by empirical Bayes interpolation method using Geographic Information System (GIS) technology. Results The positive rates of Cd, As, Pb, Cr, Cu, and Zn in the irrigated soil samples were 100.00%. The positive rate of Pb was 63.64% in the rice samples, while the rates of other metals were 100.00%. The positive rates of Cd, As, Pb, Cr, Cu, and Zn in the drinking water samples were 53.85%, 76.92%, 92.31%, 15.38%, 84.62%, and 100.00%, respectively. The results of non-carcinogenic risk assessment of oral exposure to heavy metals suggested that the contribution of heavy metals causing non-carcinogenic risk from high to low was As (70.52%) > Cd (18.03%) > Zn (6.63%) > Cu (4.12%) > Pb (0.64%) > Cr (0.06%), and the corresponding estimated non-carcinogenic risk values were 3.54 × 100, 9.05 × 10−1, 3.33 × 10−1, 2.07 × 10−1, 3.23 × 10−2, and 5.42 × 10−4, respectively. The results of carcinogenic risk assessment of oral exposure to heavy metals suggested that the contribution of studied metals from high to low was Cd (87.00%) > As (10.24%) > Cr (2.60%) > Pb (0.16%), and the estimated carcinogenic risks were 4.35× 10−3, 5.12 × 10−4, 1.30 × 10−4, and 3.08 × 10−7, respectively. Rice was the leading media associated with non-carcinogenic risk and carcinogenic risk (99.4% and 99.8% respectively). The spatial distribution characteristics of GIS showed no obvious regularity in the distribution of As in irrigated soil, rice, and drinking water. In rice and irrigated soil, the content of Cd in the villages adjacent to the mining area was obviously higher than that in the other villages, while in drinking water, the content in the villages far away from the mining area was higher. Conclusion As and Cd are the main heavy metals that increase the health risk of local residents in a typical abandoned mining area, and the distribution characteristics of the two heavy metals in different environmental media are not completely consistent.
ABSTRACT
Background The presence of formaldehyde, ammonia, benzene, toluene, and xylene in indoor air of public places has been confirmed to cause health damage. The employees of barber and beauty shops are exposed to relatively enclosed space for a long time, and could surfer more serious health risks from indoor air chemical pollutants. Objective To analyze the concentrations of common indoor air chemical pollutants in barber shops and beauty salons in Liaocheng City, and explore potential health risks of the pollutants for employees. Methods Using a stratified randomized sampling method, 8 to 10 barber shops and 5 to 10 beauty salons were selected in the main urban area of Liaocheng City to conduct monitoring of the sanitary conditions of public places in winter and summer every year from 2016 to 2021; the indoor air concentrations of formaldehyde, ammonia, benzene, toluene, and xylene in the selected sites were measured, and a questionnaire survey was conducted to collect exposure characteristics of indoor pollutants. The concentration distributions of the five chemical pollutants were obtained from the monitoring data for 6 consecutive years, and the health risk assessment model recommended by the U.S. Environmental Protection Agency was used to perform health risk assessment of inhalation exposure. Results In 2016–2021, the median indoor air concentrations of formaldehyde, ammonia, benzene, toluene, and xylene in the two types of sites were lower than the limits of Hygienic Indicators and Limits for Public Places (GB 37488-2019), but the concentrations of some monitoring sites were higher than the limits. The disqualification rates of the five pollutants in the barber shops were 16.8%, 2.7%, 2.4%, 6.4%, and 12.0%, respectively. The disqualification rate of formaldehyde was the highest in all pollutants (22.0%), while the disqualification rates of ammonia, toluene, and xylene were 1.3%, 2.0%, and 2.0% in beauty salons respectively. Both formaldehyde and benzene were found to have carcinogenic risks (CR) in the two types of public places. Both median values of CR were greater than 1.0×10−6, and both maximum values were greater than 1.0×10−4. Formaldehyde had the highest non-carcinogenic risk in the indoor air of barber shops and beauty salons. The median non-carcinogenic hazard quotients (HQ) of formaldehyde were both greater than 1, and the maximum values were 16.72 and 12.19 times of the standard value; ammonia and toluene had the lowest non-carcinogenic risks, and their maximum values of HQ were less than 1; the median HQs of benzene and xylene were far less than 1, but their maximum risk values of barber shop were greater than 1. Conclusion For the sake of worker's health, formaldehyde and benzene should be the indoor air pollutant control priority for barber shops and beauty salons in Liaocheng; formaldehyde poses the most serious health hazard to practitioners and should be given high attention and necessary measures to reduce the hazard; benzene poses certain carcinogenic risks, with some of its highest values exceeding 10−4, which is higher than the recommended safety threshold.
ABSTRACT
Background Air pollution is a major public health concern. Air Quality Health Index (AQHI) is a very important air quality risk communication tool. However, AQHI is usually constructed by single-pollutant model, which has obvious disadvantages. Objective To construct an AQHI based on the joint effects of multiple air pollutants (J-AQHI), and to provide a scientific tool for health risk warning and risk communication of air pollution. Methods Data on non-accidental deaths in Yunnan, Guangdong, Hunan, Zhejiang, and Jilin provinces from January 1, 2013 to December 31, 2018 were obtained from the corresponding provincial disease surveillance points systems (DSPS), including date of death, age, gender, and cause of death. Daily meteorological (temperature and relative humidity) and air pollution data (SO2, NO2, CO, PM2.5, PM10, and maximum 8 h O3 concentrations) at the same period were respectively derived from China Meteorological Data Sharing Service System and National Urban Air Quality Real-time Publishing Platform. Lasso regression was first applied to select air pollutants, then a time-stratified case-crossover design was applied. Each case was matched to 3 or 4 control days which were selected on the same days of the week in the same calendar month. Then a distributed lag nonlinear model (DLNM) was used to estimate the exposure-response relationship between selected air pollutants and mortality, which was used to construct the AQHI. Finally, AQHI was classified into four levels according to the air pollutant guidance limit values from World Health Organization Global Air Quality Guidelines (AQG 2021), and the excess risks (ERs) were calculated to compare the AQHI based on single-pollutant model and the J-AQHI based on multi-pollutant model. Results PM2.5, NO2, SO2, and O3 were selected by Lasso regression to establish DLNM model. The ERs for an interquartile range (IQR) increase and 95% confidence intervals (CI) for PM2.5, NO2, SO2 and O3 were 0.71% (0.34%–1.09%), 2.46% (1.78%–3.15%), 1.25% (0.9%–1.6%), and 0.27% (−0.11%–0.65%) respectively. The distribution of J-AQHI was right-skewed, and it was divided into four levels, with ranges of 0-1 for low risk, 2-3 for moderate risk, 4-5 for high health risk, and ≥6 for severe risk, and the corresponding proportions were 11.25%, 64.61%, 19.33%, and 4.81%, respectively. The ER (95%CI) of mortality risk increased by 3.61% (2.93–4.29) for each IQR increase of the multi-pollutant based J-AQHI , while it was 3.39% (2.68–4.11) for the single-pollutant based AQHI . Conclusion The J-AQHI generated by multi-pollutant model demonstrates the actual exposure health risk of air pollution in the population and provides new ideas for further improvement of AQHI calculation methods.
ABSTRACT
Background A variety of substances in drinking water are hazardous to human health and there are health risks associated with ingestion of these substances via drinking water. Objective To assess the carcinogenic and non-carcinogenic health risks of drinking water in Shijiazhuang from 2014 to 2021. Methods The collection, preservation, and testing of 10529 drinking water samples (including finished water and tap water) in Shijiazhuang were conducted from 2014 to 2021 and followed the Standard examination methods for drinking water (GB/T 5750—2006). The health risks of 15 chemicals in drinking water by oral exposure were assessed using the US Environmental Protection Agency's four-step method combined with Monte Carlo simulation. Results Among the 15 chemicals in drinking water assessed for their health risks at general exposure levels and high exposure levels via oral route in Shijiazhuang from 2014 to 2021, the leading three chemicals and related values of carcinogenic risks for adults were cadmium (1.11×10−4, 2.98×10−4), arsenic (5.88×10−5, 1.56×10−4), and chromium (5.48×10−5, 2.41×10−4), and the leading three chemicals and related values of non-carcinogenic risks were fluoride (3.57×10−1, 6.57×10−1), arsenic (1.31×10−1, 3.47×10−1), and nitrate (1.14×10−1, 5.98×10−1). The health risk values of trichloromethane and aluminum were elevated but still in acceptable ranges. Drinking water-associated health risk values were higher in males than in females, such as the cancer risk for general exposure levels of arsenic in men was 5.76×10−5, compared to 5.72×10−5 in women. The health risk values of cadmium, chromium, fluoride, nitrate, and other chemicals in ground water were higher than those of surface water, and the health risk values of trichloromethane and carbon tetrachloride were lower than those in surface water, such as the non-carcinogenic risk value for general exposure levels of fluoride in groundwater was 3.61×10−1, compared to 2.27×10−1 in surface water. Factors such as water transmission and distribution links, water period, and season affected the health risks of drinking water. The general exposure levels of trichloromethane in tap water had a higher carcinogenic risk of 1.75×10−7 compared with 8.17×10−8 in finished water. The general levels of arsenic exposure was higher in the dry season at 1.36×10−1, compared with 1.26×10−1 in the wet season. Conclusion Except that the carcinogenic risk of cadmium at general exposure levels in Shijiazhuang exceeds the maximum acceptable range recommended by US Environmental Protection Agency, the health risk values of the remaining 14 chemicals are below the maximum acceptable risk. The carcinogenic risk values of arsenic and chromium and the non-carcinogenic risk values of fluoride, arsenic, and nitrate are relatively high, but do not exceed the maximum acceptable ranges. The emphasis should be on the management of drinking water in highly exposed areas and populations.
ABSTRACT
Background Heavy metal emissions from mining and smelting areas are a global problem, and health risks associated with heavy metal contamination of soils are of great concern. The long-term mining of the largest realgar mine in Asia has caused severe arsenic and other metal pollution to the surrounding rivers and soils. Objective To understand the levels of metal contamination and health risks in agricultural soils of villages surrounding the largest realgar mine in Asia, and to lay a good foundation for further necessary pollution control actions and decisions. Methods A field survey was conducted to collect soil samples according to the Technical rules for monitoring of environmental quality of farmland soil (NY/T 395-2012), and then inductively coupled plasma mass spectrometry was used to determine the contents of 28 heavy metals [cadmium (Cd), arsenic (As), lead (Pb), mercury (Hg), chromium (Cr), nickel (Ni), copper (Cu), zinc (Zn), beryllium (Be), selenium (Se), cobalt (Co), antimony (Sb), molybdenum (Mo), vanadium (V), barium (Ba), thallium (Tl), boron (B) , bismuth (Bi), lithium (Li), manganese (Mn), strontium (Sr), calcium (Ca), rubidium (Rb), iron (Fe), magnesium (Mg), aluminum (Al), kalium (K), and titanium (Ti)]. Geoaccumulation index, single factor pollution index, and Nemerow comprehensive index were used to evaluate the degree and characteristics of single metal pollution and combined pollution in soil, respectively. A health risk assessment model was used to evaluate the risks of metals in soil to human health. Results The results of geoaccumulation index calculation revealed that 22 heavy metals were enriched in the soil, and the indexes of target heavy metals from high to low were Cd > Se > Pb >Hg > As > Co> Ni > Cu > Zn > Bi > Sb > Mo > Be> Cr > Ba >V > Li > Sr> Mn> Rb > Ca> Tl . The single factor pollution indexes of 17 heavy metals from high to low were Be > Cd > B > Mo > V > As > Ni > Cu > Pb > Zn > Co > Se > Tl > Ba > Cr > Hg > Sb. The Nemerow comprehensive index indicated all sampling points were graded as severe pollution. The mean of total non-carcinogenic health risk values and the mean of carcinogenic health risk values for the target heavy metals in the area were higher than the threshold (1) and the maximum acceptable risk (1.0×10–4), respectively. The total carcinogenic health risks for adults and children reached 1.1×10–3 and 1.67×10–3, respectively. The mean non-carcinogenic health risk values of As, Co, Cr, and Pb pollution were greater than 1, and the maximum non-cancer risk value of Sb for children was greater than 1. The mean carcinogenic risk values of Ni, As, and Cu exceeded 1.0×10–4 for both adults and children, and the maximum carcinogenic risk values of Be and Cr for children were more than 1.0×10–4. Conclusion The farmland soil around the hugest realgar mine in Asia is contaminated by multiple metals. The study soil is seriously polluted by Cd, Se, Pb, As, Hg, Be, B, Mo, V, Ni, Cu, Pb, Zn, Co, and Ba. The pollution of Ni, As, Cu, Cr, and Be is considered as carcinogenic hazards to health, while the pollution of As, Co, Cr, Pb, and Sb poses non-carcinogenic health risks. Our study findings show that the soil is polluted by Co and Group 1 carcinogen Be, which could cause health risks; although Cr and Sb have not reached severe pollution levels, there are certain health risks and also need attention.
