摘要：The current study was conducted to appraise the PM2.5 and PM10 concentration in Dalian-China and Faisalabad-Pakistan. Study was conducted for the period of one year at different stations in both cities and the results were compared according to set standards of NEQS(Pakistan), CNAAQS(China), NAAQS(USEPA) and WHO (World Health Organization). The PM2.5 concentrations in Faisalabad is variable from 22 to 49 mu g/m(3) (Average 36.5 mu g/m3), whereas PM10 variation is from 109 to 164.3 mu g/m(3) (148.3 mu g/m(3)). The PM2.5 concentrations in Dalian varied from 5.5 to 93.3 mu g/m3 (29.1 mu g/m3), whereas PM10 values varied from 10.5 to 101.1 mu g/m(3) (Average 45.9 mu g/m(3)). Both the average PM2.5 concentration in Faisalabad, in winter season is higher than the dry summer season. Both PM2.5 and PM10 concentrations were found significantly different in winter and summer seasons. The variations were considerably higher in Dalian comparing to those of Faisalabad. On average basis Faisalabad showed more PM concentrations comparing to Dalian, even higher than permissible limits set by NEQS and USEPA. Whereas the values representing Dalian are within the limits set by CNAAQS and WHO.
