In this study, the authors assessed the relationship between daily changes in respiratory health and particulate levels with diameters of (a) less than 10 μm (PM₁₀) and (b) less than 2.5 μm (PM_2.5) in Kanpur, India.

The authors have reviewed studies of human health effects that resulted from exposure
to methyl isocyanate gas that leaked from the Union Carbide plant in Bhopal, India,
in 1984. The studies were conducted during both the early and late recovery periods. Major

The authors conducted a cross-sectional study among residents of Delhi to determine the role of ambient air pollution in chronic respiratory morbidity in Delhi. The authors selected a random, stratified sample (N = 4,171) of permanent residents who were 18+ y of age and who lived near 1 of the 9 permanent air quality monitoring stations in the city.

Duplicate samples of the diet of vegetarian adults were analyzed to estimate the residues of dichloro-diphenyl-trichloroethane (DDT) and benzene hexachloride (BHC). The total food consumed by an adult per day was collected and categorized as fatty food, non-fatty food, water, and beverages. Fatty food was the main source of these chlorinated insecticides, and it contributed almost 50% of the total dietary intake. The average total DDT and BHC consumed by an adult were 19.24 micrograms/d and 77.15 micrograms/d, respectively.
