Heavy metal contamination in soil in an industrial zone and its relation with some soil properties

摘要

A study on quality of soil with reference to Zn, Pb, Fe, Mn and organic carbon in the soils of Eastern Guwahati Industrial zone, Assam has been presented in this paper. Industrial emissions which go to the atmosphere and is finally deposited on soil and or dumping of industrial wastes on disposal land may cause the environmental pollution to a great extent. Nineteen different soil samples were collected from different sites for study at East Guwahati industrial zone. The study revealed that the top soils in the area are heavily polluted with heavy metals. Statistical analysis of the data is presented to find out the correlation among measured variables. Resulting coefficient of correlation between heavy metals and other soil properties such as organic matter, pH etc. established a nonlinear relationship between the parameters
