Environmental quality assessment in a marine coastal area impacted by mining tailing using a geochemical multi-index and physical approach.

Mining has been described as an important source of contaminants to the coastal zone worldwide, which is greatly intensified in the case of tailing dam ruptures. This study assessed the environmental quality of the marine coastal area impacted by a mining disaster (Fundão Mine dam collapse on 05 November 2015, Southeast Brazil) by applying a geochemical multi-index and physical approach over 18 months (from October 2018 to March 2020). Nutrients, metal(oid)s and Polycyclic Aromatic Hydrocarbons (PAHs) were integrated by quality indexes: Canadian Council of Ministers of the Environment Water Quality Index (CWQI) and the Pollution Load Index (PLI) for water quality; Sediment Quality Guideline Quotients (SQG-q metal(oid)s and SQG-q PAHs) for sediment quality. Three scenarios regarding river discharge and wave-heights (Hs) were considered: 2018/2019-wet, 2019-dry, 2019/2020-wet. An Environmental Risk Assessment framework was built to describe the overall environmental quality in regards to water and sediment quality indexes as well as physical conditions. Here we show that the worsening of environmental quality is highly associated with the decrease of water quality by metal(oid)s (total forms of As and Ni; dissolved forms of Co and Fe) during the 2019-dry scenario when river discharge was at the lowest and the highest Hs occurred. Resuspension of fine sediment and suspended Fe(III) oxy-hydroxide nanoparticles by waves seem to be the main processes for releasing metal(oid)s into the water column. CWQI and PLI showed marginal and polluted conditions for water quality, respectively, and SQG-q for metals and PAHs indicated moderate impact in the sediment during the 2019-dry period. Toxicity to pelagic and benthic fauna is expected to occur in those conditions. Recovery of environmental quality occurred during the 2019/2020-wet scenario, which could be explained by alongshore and offshore transport of sediment and the dilution of aqueous metal(oid)s by intense river discharge on the continental shelf.

Prevalence of speech and language disorders in children in the western region of São Paulo. / Prevalência de alterações fonoaudiológicas na infância na região oeste de São Paulo.

PURPOSE: To establish the speech-language disorders in children living in the western region of São Paulo; to assess associations between diagnosis hypotheses (DH) and the age, gender and origin of referral; and to investigate the degree of agreement between the complaint and the DH at the moment of speech-language screening. METHODS: Observational epidemiological study conducted at a laboratory of Primary Health Care. A survey of 525 medical records of children between 2002 and 2011 was conducted. The following variables were analyzed: gender and age of the child; origin of referral, complaint reported by parents, diagnosis hypothesis and referrals. RESULTS: There was a predominance of male children (68.3%) and of the age group between 3 and 5 years and 11 months (48.7%), referred by a health professional (51.9%) and with more than one complaint reported by parents (26.1%). The most frequent DH were Phonological Disorder (22.9%) and more than one Diagnosis Hypothesis (19.4%). Most children were referred to a clinic-school where screening was performed (77.9%). There was an association between DH and the variables age (p <0.001*), gender (p = 0.008*) and origin of referrals (p <0.001). The degree of agreement between complaints and DHs was moderate. CONCLUSION: It has been proven that there are different DHs according to age, gender and origin of referrals. The use of speech-language screening with the information provided by parents for tracking of speech pathology is recommended.

OBJETIVO: Identificar as alterações fonoaudiológicas em crianças residentes na região oeste de São Paulo; verificar as associações entre a hipótese diagnóstica (HD) e a faixa etária, o gênero e a origem do encaminhamento; e investigar o grau de concordância entre a queixa e a HD no momento da triagem fonoaudiológica. MÉTODO: Estudo epidemiológico observacional, desenvolvido em um laboratório de Atenção Primária à Saúde. Realizou-se o levantamento de 525 prontuários de crianças atendidas entre 2002 e 2011. As variáveis analisadas foram: gênero e idade da criança; origem do encaminhamento, queixa relatada pelos pais, HD fonoaudiológica e conduta estabelecida. RESULTADOS: Houve predomínio de crianças do gênero masculino (68,3%), da faixa etária entre 3 anos e 5 anos e 11 meses (48,7%), encaminhadas por um profissional da Área da saúde (51,9%) e com mais de uma queixa referida pelos pais (26,1%). As HDs fonoaudiológicas mais frequentes foram Transtorno Fonológico (22,9%) e Mais de uma Hipótese (19,4%). A maioria das crianças foi encaminhada à própria clínica-escola em que foi realizada a triagem (77,9%). Houve associação entre HD fonoaudiológica e as variáveis faixa etária (p<0,001*), gênero (p=0,008*) e origem dos encaminhamentos (p<0,001). O grau de concordância entre as queixas e as HDs foi moderado. CONCLUSÃO: Comprovou-se que há diferentes HDs fonoaudiológicas de acordo com a faixa etária, o gênero e a origem dos encaminhamentos. Recomenda-se a utilização de screening fonoaudiológico em conjunto com as informações fornecidas pelos pais para rastreamento das alterações fonoaudiológicas.
