Abstract

• The chemical composition of soil and sediments from study area were characterized by high sulfur contents (1118-67500ppm) and high concentration of zinc (70-53600 ppm). Almost soil and sediments samples were observed highly significant concentrations of Cu value than the limit of 36mg/kg in part by EPA. SiO2 content is high in nearly almost solid samples including soil and rock. According to XRD result, prominent minerals observed quartz, calcite, pyrite and galena. The mean concentration of heavy metal in soils are ranging from S > Zn > Pb> Cu. Through the use of different indices of heavy metal contamination index (Igeo) and Enrichment rations (ER) results indicated that the study area was the most contaminated in As and Hg and followed by S and Cu.
