Arc GIS based Interpretation of Heavy Metals in Soil Samples near Coastal Areas of Badin, Sindh, Pakistan

Abstract

This study was aimed to assess the severity of heavy metal contamination in eastern coastal area of Pakistan. Agriculture lands near district Badin coastal area found contaminated due to mega surface canal drain network, carrying untreated industrial and municipal effluents along with pumped saline water. Thirty-two random soil samples were collected from different coastal areas. Arc Geographic Information System was used for spatial mapping. Soil samples from coastal areas of Badin contain average concentrations of heavy metals (mg/kg) as Hg 0.247±0.207, Ni2.622±1.107,Zn 3.121±0.929,Cu 0.059±0.066, Fe 70.447±1.163, Mn7.062±1.251,Co 0.0167±0.033,Cr0.799±0.718.
