Distribution of heavy metals in water, sediments and fish tissue (Heteropneustis fossilis) in Kali River of western U.P. India

Abstract

The present study the selected heavy metals such as cadmium (Cd), chromium (Cr), lead (Pb), Manganese (Mn) and cooper (Cu) were determined in water, sediment and gill, liver, muscle of fish H. fossilis, the concentration of Cd, Cr, Pb, Cu Mn and Zn was observed 0.009, 0.056, 0.056, 0.058, 0.049, 0.883, 0.36 mg/l in river water and 3.38, 20.11, 81.53, 258.48, 258.48, 3.40 µg/g in sediment respectively. The heavy metals concentrations in the tissue of fish H. fossilis (µg/g dry weight), Cd 30.89, Cr 20.59, Pb 15.28, Cu 30.66 and Zn 26.67 µg/g in muscle, and the Cd 30.89, Pb 15.28, Cr 20.59, Cu 30.66 and Zn 32.42 in gills and Cd 34.44, Cr 18.00, Pb 17.34, Cu31.18 and Zn 58.44 µg/g in liver. The results showed that the liver appeared to the main heavy metals storage tissues, while the muscle of fish was lover accumulator compare than gill and liver. All the metals concentration exceeded the detection limits except than Mn. The results indicated that the selected fish does not feed directly without proper treatment of riverin ecosystem.
