IMMENSE INDUSTRIALIZATION AND THEIR AIR PROMINENT POLLUTANTS EFFECT ON URBAN AIR QUALITY INDEX

Abstract

On the basis of the reported air quality index API and air pollutant monitoring data obtained at thePeshawar city over the last seven years, the characteristics of air quality prominent pollutants andvariation of the average annual concentrations of SO2, NO2 total suspended particulate TSP fineparticulates PM10 CO and dust fall in Peshawar were analyzed. Results showed that SO2 and NO2were the prominent pollutants in the ambient air environment of Peshawar. Of the prominentpollutants TSP accounted for nearly 63 % SO2, 32.8 ppb NO2, 147 ppb of CH4, 13.8 ppb of CO, 94.5µg/m3 of MC and 0.60 ppb of O3 respectively in 2013. NO2 to SO2 comparison ratio initially declinedto 39.3 in 2009 and then starts to increase to 42.5 in 2010 while in 2013 reached upto 44.8 and O3 toSO2 ratio in the last year of observation, the ratio drop to 0.01830 µg/m3. Concentrations of airpollutants have shown a upward trend in recent years but they are generally worse than ambient airquality standards for EPA-USA, Pakistan and EU. SO2 and NOx pollution were still serious implingthat waste gas pollution from all kinds of vehicles had become a significant problem forenvironmental protection in Peshawar. The possible causes of worsening air quality were alsodiscussed in this paper
