The diurnal and seasonal variation of PM10, SO2, NO2, NH3 and water-soluble compounds were studied in Naraina industrial area in Delhi from January to December, 2017. The concentrations of PM10 and sometimes NO2 exceeded the Indian National Ambient Air Quality Standards, while the concentrations of SO2 and NH3 were within the standard. The selected parameters varied from season to season, with higher concentrations observed at night possibly due to the formation of inorganic secondary particulate matters and low wind speed in the ambient air.
The diurnal and seasonal variation of PM10, SO2, NO2, NH3 and water-soluble compounds were studied in Naraina industrial area; Delhi from January to December, 2017. It was observed that annual average concentrations of PM10, SO2, NO2, NH3, SO42-, NO3-, NH4+,Na+, K+, Ca2+, Mg2+, Cl- and F- in the day time were 227 +/- 91, 9 +/- 5, 59 +/- 22, 65 +/- 15, 17.45 +/- 5.14, 17.60 +/- 4.94, 8.66 +/- 2.94, 4.05 +/- 1.08, 3.46 +/- 0.91, 10.38 +/- 4.48, 3.15 +/- 0.99, 43.06 +/- 5.20 and 0.50 +/- 0.12 mu g m(-3), respectively and night time were 320 +/- 127, 14 +/- 7, 82 +/- 25, 83 +/- 20, 22.64 +/- 5.22, 21.66 +/- 5.0, 11.81 +/- 3.47, 3.29 +/- 0.87, 3.02 +/- 1.19, 7.55 +/- 3.16, 2.49 +/- 0.95, 31.86 +/- 4.70 and 0.37 +/- 0.12 mu g m(-3), respectively. PM10 and sometimes NO2 concentrations exceeded the Indian National Ambient Air Quality Standards. SO2, and NH3 concentrations were within the standard. The selected parameters varied from season to season. In the night time, selected parameters concentrations were high in comparison to day time might be due to formation of inorganic secondary particulate matters and low wind speed in the ambient air.
