ABSTRACT

By using freshwater fishes, the LC50 96 hr values of zinc, cadmium and lead were determined
through static bioassays. On exposure to the sub lethal concentrations of the metals, tissues like
liver, kidney and muscle were used to estimate the DNA and RNA content. Both DNA and RNA levels
decrease in the tissues of the fishes suggesting the impairment of protein synthesis machinery. The
study was also indicative of manifestation of malfunction and degenerative changes in organ system.
Key words: Tissues, DNA and RNA content, Heavy metals, Cyprinus carpio.
