Spatial distribution and correlation characteristics of heavy metals in sewage and tube well water irrigated peri-urban areas of Haryana

Abstract

A study on “spatial distribution and correlation characteristics of heavy metals in peri−urban areas of Haryana, India” was conducted during 2018−19 in sewage and tube well water irrigated areas of Mohindergarh and Narnaul cities of Haryana. In this study soil samples were collected using Global Positioning System (GPS) by following random sampling method and analyzed for physico−chemical properties and DTPA extractable heavy metals (Zn, Cu, Cd, Cr, Pb, Ni and Co). In soil, chemical properties like electrical conductivity (EC), organic carbon (OC) and cation exchange capacity (CEC) found to be higher in sewage irrigated soils compared to tube well irrigated whereas pH and CaCO higher in tube well irrigated than sewage irrigated 3 soils of the study area and DTPA extractable Zn content was higher followed by Cu > Pb > Ni > Cr > Co > Cd in sewage irrigated soils than tube well irrigated soils and found within the permissible limit.
