Abstract: Chromium is an important metal used in vast range of industrial units. The major contributor remains tannery industry. The aim of the present study was to determine wastewater quality of tanneries effluent of Korangi Site with the estimation of chromium pollution levels. Analysis of selected parameters (TSS, TDS, pH, BOD, COD and chromium) have shown results to be within acceptable limits (in April, May and June) except for chromium, having exceeded concentrations of 10.26ppm and 13.05ppm in the month of May and June respectively. The analysis result emphasized the use efficient tanning processes and implementation of best industrial practices, recycling and recovery of chromium. It is recommended to use efficient treatment plants having feasible physico-chemical and/ or biological treatment options, and implementation of polluters pay principle for individual sense of responsibility of industrial units against deuteriation of environment and carcinogenic effect of chromium on human health.
