A Preliminary AssessmentandControlStrategyof SizeSegregated Pollutants in Urban and Peri-urban Areas ofMetropolitan Faisalabad,Pakistan

In recent years, Pakistan has experienced severe and persistent air pollution associated withurbanization and industrialization and it has substantial affects on ecosystem and air quality.Inurban and peri-urban areas,maximum TSP concentrations wereobserved at SatianaRoad (987μm-3)and Chak 215 RB(1123μgm-3).Similarly,maximumPM10concentrationswererecordedat Gutte Wala (782μgm-3) and Chak 215 RB(893μgm-3), while maximum PM2.5concentrationswereobserved at Madina Food Mill (621μgm-3) and Chak 215 RB (654μgm-3).Thestatisticalresults suggested that there weresignificant difference between urban and peri-urban areas.Majority ofsize segregated pollutants including TSP, PM10and PM2.5were found with highervalues than the United States EnvironmentalProtection Agency(US-EPA),World HealthOrganization(WHO)andNational EnvironmentalQuality Standardsfor Pakistan (NEQS-Pak)limits for both urban and peri-urban areas.However,only 4%, 8% and 4% for TSP, PM10andPM2.5,respectively inurban andin peri-urban samplesforTSP (40%)PM10(60%) andPM2.5(44%) were found under prescribedguidelines.Furthermore, we have also compared metropolitansize segregated pollutant (PM10)with other Pakistan and Asian metropolitan’s citiesandpurposeda controlstrategytoimprove air quality in Faisalabad.
