Study of Heavy and Transition Elements in Tannery Effluents and its Impact on Soil around Kanpur, India [ READ ]
Dr.Nivedita Agrawal and Raviraj Singh
Kanpur City has become a large tannery complex with nearly 450 tannery .The tannery industries are causing severe environmental pollution. Water and Soil pollution through the discharge of industrial effluents is causing severe problems. The pollutants include As, Cr, Cd, Cu, Fe, Hg, Pb and Zn, which are considered as toxicants. The presence of heavy and transition metal significantly changes the water and soil characteristics. The present studies were conducted in summer season of 2014 in 08 locations of tannery affected area Jajmau, Kanpur and it deals with the assessment of pollution due to toxic heavy metals in the industrial waste water effluents collected from Jajmau, Kanpur. The concentration level of BOD, COD, TS, TSS, magnesium, phosphate, nitrate, fluoride, phenol, oil and grease were above the permissible limit. The metals like Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn were found in significant quantities. We found the soils are highly contaminated due to tannery activity at Jajmau, Kanpur.
