Abstract
Coastal areas of Karachi, Sindh, Pakistan were selected with the intention of study the accessibility of heavy metals and their concentrations in the surficial sediments (<60μm). These top soil samples were analyzed for Fe, Mn, Cr, Pb, Zn, Cu, Co, and As to scrutinize metals concentrations in sediments. Evaluation of anthropogenic pollution in sediments contamination indicator by Single-factor index analysis. Basic concentration of Mn is maximum in coastal sediments followed by Fe, Zn, Pb and As that is Mn > Fe > Zn > Pb > Co > Cu > As. This study exposed that confined geology has not revealed a few noteworthy influence on coastal sediments of the study area. The consequences of this study showed that Fe, Cr and As are the mainly severe pollutants in creek / beach sediments especially at Port Qasim industrial area i.e. (average 1104, 31 & 1.9 ppm) and Ketti Bunder i.e. (average 45, 0.67 & 5.03 ppm).
