Investigation Of Heavy Metal Contamination In Soil Proximal To Municipal Solid Waste Dumping Station, Hisar, Haryana

Abstract

Heavy metals are non-biodegradable pollutants, they pose a serious hazard to human health. The quantity of heavy metals in dumping site increases as different sources of these metals are disposed of with municipal solid waste. A study of the effect of municipal solid waste on heavy metal contaminations in soil proximal to dumping station located in village Dhandoor, of district Hisar, Haryana, was carried out. The soil samples were collected from dumping site in pre-monsoon and post-monsoon. The concentrations of Iron, Copper, Zinc, Chromium, Lead and Cadmium were analyzed by Atomic Absorption Spectrometer. The concentrations of heavy metals in each sampling area were higher in post-monsoon season and in both the seasons the mean concentrations of heavy metals followed the order: Fe > Cu > Zn > Cr > Pb > Cd. This study shows that the heavy metal contaminations in soil is strongly affected by municipal solid waste.
