Air Quality Assessment at Industrial cum Residential Areas of Karachi City in Context of PM2.5
This study is illuminating the distinctiveness of Particulate matter having 2.5μm size (PM2.5) with water soluble ions like SO4-2, NO3- and Cl- along with carbonaceous aerosols (i.e. BCIR and BCUV) as well as elemental profile for the period December 2012 to January 2013 at residential cum industria...

| description | This study is illuminating the distinctiveness of Particulate matter having 2.5μm size (PM2.5) with water soluble ions like SO4-2, NO3- and Cl- along with carbonaceous aerosols (i.e. BCIR and BCUV) as well as elemental profile for the period December 2012 to January 2013 at residential cum industrial site to investigate the quality of air of the mega city Karachi. Twenty-six samples have been collected for 24-hours during the study period on PTFE samples. Mean concentration of PM2.5 is found to be 112μg/m3 which is much higher than the WHO guideline (i.e.25 μg/m3). Both, BCUV and BCIR, have high contents during the study period i.e. 3.85μg/m3 and 5.09μg/m3 mean values respectively. Na, Mg, Cl, K, Ti, Cr, Mn, Ni, Cu, Zn, Br, Rb, Sr, Zr, Er, Lu, Pb, W, Sn, Sb and Ce were also examined in elemental analysis from which Al, Si, S, Ca and Fe shows relatively higher concentrations among the targeted elements. Pearson‘s correlation shows that PM2.5 is significantly correlated with BC whereas SO4-2 and NO3- originate from similar sources. HYSPLIT backward air mass trajectories show that regional sources are contributing in high concentrations of fine particulates. |
