ABSTRACT
RESUMO A intensificação das atividades industriais e o aumento das emissões veiculares têm contribuído significantemente para o aumento da poluição atmosférica nos centros urbanos. Neste trabalho, avaliou-se a qualidade do ar na área do distrito industrial de Maracanaú, no estado do Ceará, importante área industrial da Região Nordeste do Brasil. As amostragens foram realizadas durante o período de novembro de 2015 a abril de 2016, totalizando 30 coletas com duração de 24 h cada. Realizaram-se coletas para poluentes, como o material particulado total (PTS) e inalável (MP10), NO2, SO2, O3 e metais pesados (Sb, Cd, Pb, Cu, Fe, Mn, Ni e Zn) associados ao PTS e ao MP10. O O3 foi determinado por absorção no ultravioleta (254 nm), e estimaram-se as concentrações dos metais por espectroscopia de absorção atômica. Os valores médios observados para os poluentes foram de: 51,3 µg/m3 de PTS; 46,1 µg/m3 de MP10; 8,9 µg/m3 de SO2; 8,3 µg/m3 de NO2; 38,5 µg/m3 para O3 em 8 horas e 48,4 µg/m3 para O3 em 1 hora. Para os metais, o Fe (14,9 µg/m3) foi o mais abundante em ambos os particulados. Todos os parâmetros encontram-se em conformidade com os valores estabelecidos pela legislação brasileira, e somente o MP10 apresentou em 16,7% das amostras concentrações acima (média de 74,5 µg/m3) do recomendado pela Organização Mundial da Saúde. Em geral, a qualidade do ar na área industrial em estudo pode ser considerada boa, segundo os valores de índice de qualidade do ar (IQAr) recomendado pela agência de proteção ambiental americana.
ABSTRACT The intensification of industrial activities and the increase in vehicular emissions have contributed significantly to the increase in atmospheric pollution in urban centers. In this context, the present study aimed to monitor the air quality in the area of Maracanaú Industrial District, in the state of Ceará, an important industrial area in northeastern region of Brazil. Samples were collected during 24 h from November 2015 to April 2016 for pollutants such as total suspended (TSP) and inhalable particle materials (PM10), NO2, SO2, O3 and heavy metals (Sb, Cd, Pb, Cu, Fe, Mn, Ni, and Zn) associated with TSP and PM10. Ozone (O3) was determined by ultraviolet absorption (254 nm) and the concentration of heavy metals were estimated by atomic absorption spectroscopy. The mean values observed for the pollutant concentrations were: 51.3 μg/m3 for TSP; 46.1 μg/m3 for PM10; 8.9 μg/m3 for SO2; 8.3 μg/m3 for NO2; 38.5 μg/m3 for O3 in 8 hours and 48.4 μg/m3 for O3 in 1 hour. Among metals, Fe (14.9 µg/m3) was the most abundant species in both particulates. All the parameters analyzed are in accordance with the values established by the Brazilian legislation and only PM10 are above the recommended by the World Health Organization in 16.7 % of the samples (mean 74.5 μg/m3). In general, the air quality in the industrial area under study can be considered good, according to the estimates of the air quality index (AQI) recommended by the US Environmental Protection Agency.
ABSTRACT
Spirometry is an important method for evaluating lung functions in children and can identify the type and the pattern of respiratory dysfunction. Air pollution is strongly associated with human health, and the results of air pollution include an increased mortality rate, an increased number of patients with respiratory or cardiovascular diseases. Main objective is to assess the degree of lung function impairment among school children of Industrial Area. Methods: The present study was conducted at a school of industrial area i.e., Advani Arlicon Higher secondary School, Urla Road, Birgaon of Raipur city from April to August 2012. The subjects were evaluated through pulmonary function test by using Spirometry method. Permission from Institutional Ethics Committee was obtained. Initially informed individual consent was taken from all the patients included in the study. Results: In the study group of Cases (Industrial Area school children), amongst total 200 subjects; there were 56 subjects aged between 11 t0 14 years and 144 subjects aged between 15 to 18 years. Mean FEF 25% - 75% (in liters/Sec) for Males was found to be 4.110 ±0.6836, Mean FEF25% -75 %( in Liter/Sec) for Females was found to be 3.768±0.6241. Mean FEF50% (in liters/Sec) for Males was found to be 4.426±0.6879, Mean FEF50% (in Liters/Sec) for Females was found to be 4.085±0.6787. Mean Lung Age (in Years) for Males found to be 17.166±2.368, Mean Lung Age (in Years) for Females was found to be 17.929±2.444. Conclusion: To conclude, there is a definite association between chronic exposures to severe urban air pollution & reduced pulmonary functions. The strategies (use of mask, regular health checkup and awareness on health impacts of pollution) need to be adopted by high risk persons for betterment & for healthy lifestyle.
ABSTRACT
Background: Accidental deaths and injuries are inevitable in this modern way of living. Methods: We retrospectively studied unnatural death cases brought for the post mortem examination at district mortuary of J P Nagar in the two years from 2014-2015. All the cases of death which are caused due to the injuries within the industrial premises were included in the study and the results are analysed. Results: Death from industrial area accounted for 5.01% of total autopsies. Male outnumbered the female in the ratio of 5:1 and they suffered injuries mostly in their third decade of life. Maximum incidences occurred in the morning shift followed by afternoon shift and are brought dead to the hospital. Conclusions: The most common cause of death in industrial area is head injury either due to falling of heavy object or by fall from height. This can be attributed to the poor enforcement of safety measures in these areas.
ABSTRACT
Air pollution tolerance index (APTI) calculated for various plant species growing in vicinity of three different industrial areas (Paper mill, Sugar mill, Thermal Power Plant) and Yamuna River belt of Yamuna Nagar. Studies were carried out to determine the physiological response of ten plant species. The leaf samples collected from these plant species were used to determine their plant APTI by calculating the ascorbic acid, total chlorophyll, pH, and relative water content for all selected sites. Highest pH, relative water content, ascorbic acid and total chlorophyll was observed in Castor (9.86), Parthenium (96.99%), Ficus benghalensis (14.90 mg g-1) and Amaranthus (7.08 mg g-1) at Yamuna river, Thermal power plant, Yamuna river and paper mill respectively. It was concluded that out of ten species studied only one species (Ficus benghalensis) showed moderately tolerant response in all selected sites, while other species showed sensitive response. According to observed APTI values, Ficus benghalensis showed the highest value (21.65) at sugar mill followed by thermal power plant (19.38), Paper mill (17.65) and Yamuna River (17.61). The lowest APTI values were reported in Oxalis corniculata (6.42) at Yamuna River belt followed by Malvestrum at sugar mill (7.71).
ABSTRACT
Se realizó una intervención comunitaria en los trabajadores de 30 entidades laborales ubicadas en la zona industrial del municipio de Santiago de Cuba, durante el bienio 2009-2010, para establecer el empoderamiento sanitario en ellos. Entre los principales resultados figuró el logro de la capacitación de todos los líderes sindicales y políticos, así como de la brigada de vigilancia y lucha antivectorial, por el contrario de los dirigentes administrativos, de los cuales solo 86,6 % participó en el estudio porque no lo consideraban una responsabilidad inherente a su cargo. Respecto a la situación ambiental, se observó un incremento de los criaderos de Aedes aegypti durante la temporada lluviosa, asociado a una mayor acumulación de agua en los depósitos naturales o artificiales, o ambos; no obstante, hubo un impacto social en el ordenamiento del medio en 9 de estas instituciones a través de la integración de los intereses comunitarios, la planificación en conjunto y la evaluación participativa, que conformó la principal estrategia. Finalmente, se recomendó implementar este proceso de empoderamiento sanitario en el resto de los centros de trabajo de la zona industrial con vistas a prevenir las enfermedades transmitidas por mosquitos y roedores.
A community intervention was performed in workers of 30 entities located in the industrial area of Santiago de Cuba municipality during the biennium 2009 -2010 to establish the health empowerment in them. Among the main results was the training for all union and political leaders and antivectorial surveillance and control brigade, unlike administrative leaders, of whom only 86.6% participated in the study because they considered it was not their responsibility. Regarding the environmental conditions, an increment of Aedes aegypti breeding sites was observed during the rainy season, associated with increased accumulation of water in natural or artificial reservoirs or both. However, there was a social impact on environmental management in 9 of these institutions through the integration of community interests, joint planning and participatory evaluation, which was the main strategy. Finally, it was recommended to implement this process of health empowerment in other workplaces in the industrial area to prevent diseases transmitted by mosquitoes and rodents.
ABSTRACT
This study was conducted to investigate food and meal preference of workers (435 male and 212 female) in the Chonnam Yeosu industrial area. The results of the survey were analyzed by principal components analysis. The results were obtained as follows: 19.3% of the subjects were twenties, 28.3% were thirties, 28.8% were forties and 23.7% were fifties. Females liked rice rolled in dried laver, rice cakes, janchi-noodle and breads, on the other hand males liked thick beef soup, loach soup, an eel stew and soju. The young liked instant noodles, fried chicken, sweet and sour pork, pork cutlet, pizza, hamburger, ham, sausage and fruit beverage, on the other hand the old liked a fish pot stew, loach soup, eel stew, fish boiled in soy with spices, panfried fish, sea slug, ascidian, bunder, green laver and boiled burdock-lotus root in soy. Females who are young liked hamburger and sweet and sour pork whereas males who are young liked instant noodles, pork cutlet, ham, sausage and fruit beverage. Aged females liked fish boiled in soy with spices, panfried fish, bunder, green laver, boiled burdock-lotus root in soy whereas aged males liked a fish pot stew, loach soup, eel stew, sea mussel and oysters. Boiled rice was located within the middle irrespective of age and sex, but noodles, wheat flour meal, fast foods and fruits were situated at the young female side. Aged males liked soup and pot stew. Young males liked meats and eggs whereas fish and shellfish and kimch were located at the aged people side. Aged females liked sea weeds and most people disliked vegetables but females liked some vegetables irrespective of age. Processed foods, salted foods, and alcohol were generally disliked foods by subjects but males liked those foods. Soybean curd was liked more males than females, and teas, except coffee, was liked by males.

This study was carried out to examine information regarding usage of health improving agents and health status of male workers in the Chonnam Yeosu industrial area. We obtained data by means of a questionnaire from 329 men. Of the subjects 44.7% were in their forties, high school education was 43.0%, married was 83.0% and 1,500~3,000 thousand won in monthly income was 35.8%. Average height and weight of the subjects was 171.8 +/-5.4 cm and 70.5 +/-8.1 kg. Average BMI was 23.8 +/-2.2. Drinking rate of respondents was 85.5%, the drinking rate of daily workers was significantly higher than rotation workers (p < 0.05). Rotation workers exercised more regularly than daily workers (p < 0.001). Subjective symptoms of the subjects always had eye problems (11.7%), shoulder aches (5.8%), ache in one's empty stomach (4.7%) in decreasing order. 21.4% of the subjects had a disease, and liver disease was the highest in the subjects; the second was cardio-vascular disease. Interval of health food intake was highly irregular (62.7% of respondents), and keeping healthy was the main motivation for the usage of health foods. Health improving agents included oriental medicine, animal protein based restorative foods, nutrition supplements, health supplements, and natural foods. 33.3% of the subjects took health supplements, nutrition supplements (29.1%), oriental medicine (20.6%), natural foods (16.7%) and animal protein based restorative foods (3.9%), in respective order. Health improving agents were consumed higher in liver disease than other diseases. This study suggests that nutritional education and monitoring should be implemented for industrial workers to prevent life-habit diseases and to keep proper self-management of health status under special environments.
