The samples were collected from the tanneries located in Korangi industrial area, have high chromium concentration exceeding
the tolerable limit.The effluents from tanneries are directly disposed off into streams without any treatment or ineffective method
are used for treatment. The concentration of chromium was found to be 18.57-.170.12 ppm in residue and 15.20-185.50 ppm in
filtrate of korangi industrial effluent in 2011. The conductance varies from 6.7 to 175 S/m which shows the high concentration of
ionic species. The pH of samples was found to be mostly alkaline (7.0-8.9) except in T1 of January.
