The study dealt with the concentration of air pollutants emitted from Kushtia sugar mills in Jagati region of Bangladesh in order to evaluate their impact on human health. The dispersion of air pollutants from sugar mill’s chimney was obtained through point source Gaussian dispersion model. The air pollutants were monitored during winter season in 2011-2012. A questionnaire survey was randomly carried out in a small scale at the study area. The result showed that the maximum concentration of SO2, NOx and PM10 were 28.837 μg/m3, 76.177 μg/m3 and 380.339 μg/m3 respectively. The particulate matter (PM10) concentration was found to be very high whereas sulfur dioxide (SO2) and nitrogen oxide (NOx) concentrations were low at the study area. The calculated value of air pollution index (API) was 88.18 which indicate that heavy air pollution can predispose individuals to heart and lung disease in the study area people. This study revealed that the concentration of particulate matter found in Kushtia sugar mill had exceeded the minimum level according to the WHO standards. The high concentration of PM10 is suggested to affect human health and environmental conditions in the study area.

The present study was conducted on cement industry at Hattar Industrial Estate, Haripur for assessment of particulate matter (PM10 & PM2.5) and its health impact on factory workers and nearby local community. Ten samples were collected from different units of cement industry and analyzed for PM10 & PM2.5.The concentrations of PM10 & 3 2.5 varied in different units of cement industry. The highest mean concentrations of PM10 &PM 2.5were found 1552 and 7867.5 (μg/m³) in main crusher and cement mill respectively. Eighty percent of samples (both PM10 &d PM 2.5) were above the National Environmental Quality Standards (NEQS), set by Pakistan. The air pollution index (API) revealed, that majority units released high amount of particulate matter to environment, which pose significant health risk to local community. The particulate matter released by cement industry have significant impacts on human health especially the respiratory system. Therefore, it was recommended to install air pollution control devices for particulate matter, so as to minimize dust pollution inside the industry and nearby localities.
