Abstract:

In recent years, Pakistan has experienced severe and persistent air pollution associated with urbanization and industrialization and it has substantial affects on ecosystem and air quality. In urban and peri-urban areas, maximum TSP concentrations were observed at Satiana Road (987 µm-3) and Chak 215 RB (1123 µg m-3). Similarly, maximum PM10 concentrations were recorded at Gutte Wala (782 µg m-3) and Chak 215 RB (893 µg m-3), while maximum PM2.5 concentrations were observed at Madina Food Mill (621 µg m-3) and Chak 215 RB (654 µg m-3). The statistical results suggested that there were significant difference between urban and peri-urban areas. Majority of size segregated pollutants including TSP, PM10 and PM2.5 were found with higher values than the United States Environmental Protection Agency (US-EPA), World Health Organization (WHO) and National Environmental Quality Standards for Pakistan (NEQS-Pak) limits for both urban and peri-urban areas. However, only 4%, 8% and 4% for TSP, PM10 and PM2.5, respectively in urban and in peri-urban samples for TSP (40%) PM10 (60%) and PM2.5 (44%) were found under prescribed guidelines. Furthermore, we have also compared metropolitan size segregated pollutant (PM10) with other Pakistan and Asian metropolitan’s cities and purposed a control strategy to improve air quality in Faisalabad.
