A survey analysis of heavy metals bio-accumulation in internal organs of sea shell animals affected by the sustainable pollution of antifouling paints used for ships anchored at some domestic maritime spaces

Some samples of sea shell animals stuck and multiplied on the bottom （beneath the seawater） coated with antifouling paints were collected at some domestic maritime spaces, and the content of heavy metals was detected through Inductively Coupled Plasma-Mass Spectroscopy. Meanwhile, comparison with sea shell animals was made on market for edible use. It shows that the content of heavy metals in internal organs of these marine animals is very high due to the large amount of copper and zinc contained in the antifouling paints, and this also does severely harm to sea environment and ecology. To study and develop the novel antifouling paints without copper（I） oxide is an imperative task which brooks no delay.
