AIR QUALITY MONITORING OF PARTICULATE MATTER (PM2.5 & PM 10) AT NIAZI AND DAEWOO BUS STATION, LAHORE
In this study, Niazi and Daewoo bus station, Lahore were selected for the measurement of Particulate matter, PM2.5 and PM10. The concentration of PM2.5 and PM10 was measured using an air sampler for one week in each station in May 2016. The measurement results were strongly associated with bus traffic volume, type of transport and fuel. Overall results revealed that the concentration of PM2.5 and PM10 was higher than the permissible limit given by National environmental quality standard (NEQS). The emissions from buses in Niazi bus platform were higher than Daewoo station. This was because the bus traffic volume was high as compared to Daewoo station and the internal maintenance of buses was also different. It is concluded that vehicles are the major contributor of PM2.5 and PM10 pollution which have hazardous effects on air quality and the health.
