long term effects of cadmium, copper, lead and zinc exposure on the growth of juvenile green mussel (perna viridis)

In this study Perna viridis was exposed to cadmium, copper, lead and zinc under long term toxicity test to investigate the changes in growth in terms of gain in length, weight and condition factor of the test organism. From the data obtained it is clear that the lower concentrations of cadmium, copper, lead and zinc under long term exposure significantly reduced the growth of Juvenile P.viridis. P.viridis is more sensitive to lead and cadmium compared to copper and zinc, making them suitable for environmental monitoring.
