|Abstract:||Monitoring of PM 10 (Particulate matter, aerodynamic diameter ≤ 10µm) and SPM (Suspended Particulate Matter) levels in ambient air around a cement plant at Jamul, District-Durg, Chhattisgarh state was carried out in post-rainy, winter and summer seasons. A significant contribution of PM 10 and SPM levels in ambient air from stack emissions has been observed. PM 10 and SPM levels were found to be in the ranges of 84-220µg/m3 (PM 10) and 174-473 µg/m3 (SPM) in post-rainy season; 150-480 µg/m3 (PM 10) and 551-1120 µg/m3 (SPM) in winter season; and 110-460 µg/m3 (PM 10) and 365-978 µg/m3 (SPM) in the summer season, respectively, in downwind direction. Smaller values of such emissions were obtained in sites of upwind direction. Ratios of PM 10 to SPM and correlation coefficient values between PM 10 and SPM were also workout. A positive correlation coefficient was obtained between PM 10 and SPM. Order of occurrences of PM 10 and SPM at downwind direction in all three seasons was winter> summer> post-rainy.|
