Abstract
© 2015, Pakistan Agricultural Scientists Forum. All rights reserved. Particulate matter exhibits different behavior with altitude. A comparative analysis was carried out to monitor PM<inf>1</inf>, PM<inf>2.5</inf>, PM<inf>4</inf>, PM<inf>10</inf> and PMTotal at elevations above 3000 m in both China and Pakistan. Real time monitoring of PM was carried out at both sites using a DustTrak DRX (model 8533, TSI Inc.) for 24 hours each. In Pakistan, the average value of PM<inf>Total</inf> was 415 ± 16 μg/m<sup>3</sup> while in China the value was considerably lower i.e. 110 ± 57 μg/m<sup>3</sup>. The 24-hour mean values recorded were well above the WHO recommended limit of 25 μg/m<sup>3</sup>. These results indicate that, even at sites some distance from anthropogenic sources, PM concentrations still pose a health risk.
