| 520 | __ | |aGeospatial as well as geostatistical approaches using GIS tool to assess and characterize heavy metals namely Cd, Cr, Cu, Ni, Zn, Pb, Fe, As and Mn in soil, crop, and groundwater, their degree of pollution level, and phytoextraction behaviours of key metals were carried-out in Nagaon district of Assam during 2018 to 2021. To appraise the potential heavy metal sites, a random systematic method was used for sampling strategy by dividing the study area into a grid of 5 km× 5 km and collecting 160 composite soil samples from 0-15 cm depth for the total content of heavy metals using Atomic Absorption Spectrophotometer (Model: iCE 3500, Thermofisher). Geospatial analyses from different thematic maps of heavy metals revealed significant vulnerable points of elevated concentrations of Cd (gt 0.31 mg/kg ), Pb (gt 24.45 mg/kg ) and Ni (gt 0.05 mg/kg ) in soils and Cd (gt0.01 mg/L), Cr (gt0.05 mg/L), Cu (gt1.3 mg/L ), Fe (gt 0.3 mg/L ), As (gt 20 mg/L ) and Mn (gt 0.1 mg/L ) in groundwater which is presumed to be due |
