Accumulation of lead in the tissues and effects on growth rate of freshwater Cyprinus carpio

Abstract

The present study was undertaken to determine the accumulation of heavy metal Lead (Pb) in different tissues of Cyprinus carpio as well as description the growth rate of C. carpio. The experimental fish were exposed to lead at sub lethal concentration (0.4 mg/l) and (0.2mg/l) for 60 days by added Pb in water aquarium. The element of lead was assayed by using flame atomic absorption spectrophotometer (FAAS) and the results were given as µg/gm. dry wt. The high level lead accumulation was found to be in liver in T1 (98.77±41.46) µg/gm and T3 (94.9568.20) µg/gm. The order of lead accumulation in organs was liver > gill > kidney > spleen. As well as showed a decrease in the growth rate of the fish because of the addition of lead element in a water aquarium.
