| dc.description.abstract | A field survey and laboratory study on “Spatial distribution and background levels of heavy metals in different soil series of district Hisar” was conducted during 2017-18 in five well established soil series which are comes under Aeolian and upper alluvial plain of Hisar district. The surface and profile samples using GPS were collected and analyzed for physicochemical properties, total and soluble concentrations of heavy metals (Pb, Cr, Cd, Co and Ni). The soils of different soil series of Hisar district were moderately alkaline to strongly alkaline (mean pH 8.0-8.5), mean EC (dS m-1) 0.10-0.17 (non saline), low to medium (0.39-0.51%) organic carbon , sandy to sandy clay loam texture with low to moderate (8.64-12.85 cmol kg-1) CEC and calcium carbonate content was < 5 %. The mean ranges of soluble heavy metals concentration were 0.56-1.30, 0.03-0.17, 0.01-0.04, 0.00-0.02 and 0.03- 0.16 mg kg-1 for Pb, Cr, Cd, Co and Ni respectively, which below the permissible limit. The relationship between different physico-chemical properties and heavy metal concentrations in soils were analyzed by Pearson’s correlation coefficient which found significant correlations between different quantitative variables such as clay and CEC with pH, EC, OC and silt content; lead with pH, OC, CEC, silt and clay content; chromium with pH, CEC, silt and clay content; cobalt with OC, silt and clay content; nickel with OC, CEC and clay content. The non uniform distribution of total heavy metals contents were found in all series. Background levels of heavy metals in all the series were less than one (<1) showed soils are non-contaminated. | en_US |
