TOXIC EFFECTS AND BIOACCUMULATION OF CADMIUM, COPPER, LEAD AND ZINC IN POST LARVAL STAGES OF PENAEUS MONODONInternational Journal of Development Research (2011)
AbstractThe acute toxicity and bioaccumulation of cadmium, copper, lead and zinc to Penaeus monodon (Tiger prawn) was evaluated in static tests. Each test lasted up to 4 d and LC50 values were also calculated. The toxicity of each metal increased with exposure time for cadmium, copper, lead and zinc. The 96 hours LC50 values for cadmium, copper, lead and zinc were 1.72, 0.66, 0.41, 2.36 mg/l. Lead was toxic metal to P.monodon than zinc followed by cadmium and copper tested. The order of toxicity was Pb>Cu>Cd>Zn. The bioaccumulation study showed that the zinc was accumulated in a higher concentration followed by copper, lead and cadmium.
