Toxic metal distribution in soils of Kaveh industrial city, Iran.

2 Abstract: The concentrations of Cd, Pb, Cu, Mn, Zn and Ni were determined from 72 soil samples collected in surface soils of Kaveh industrial city. Multivariate statistics analysis and GIS were used to identify heavy metal sources and their spatial pattern. Principal component analysis coupled with correlation between heavy metals showed that primary inputs of Ni were due to anthropogenic sources and Cu and Mn were associated with pedogenic and anthropogenic factors, while, Cd, Zn and Pb were associated with pedogenic factors. Ordinary kriging was carried out to map the spatial patters of heavy metals. The high pollution sources evaluated was related with usage of urban and industrial wastewater. The results of this study helpful for risk assessment of environmental pollution for decision making for industrial adjustment and remedy soil pollution.
