Abstract: | Cadmium bioaccumulation in Nodipecten nodosus reared on a marine farm in a tropical bay was measured in muscle tissue and the digestive glands in animals ranging from
6 to 16 months. No bioaccumulation tendencies regarding Cd concentration were observed in muscle tissue (below 1 μg g−1), while in the digestive gland concentrations remained below 5 μg g−1 until the organisms reached 10 months, and reached levels above 10 μg g−1 from 12 months onwards (reaching 27 μg g−1). This is the same bioaccumulation pattern noted in animals transplanted to a different Cd exposure. Allometry and environmental
factors cannot explain this sudden increase. |
