ACCUMULATION OF MERCURY IN BLOOD CLAM FROM BOWAI GULF

Accumulation rules of mercury by blood clam (Arca subcrenata Lishke) from Bohai Gulf have been studied. Mercury concentration in soft parts have been related to those in the environment level on the shore and size of animals have also been considered. Uptake ability of mercury in blood clams is high, with the concentration coefficient 1.8×10³ Hg contents In its soft part are related to those in seawater and in sediment, the relationship may be expressed by a dual linear regression equation. The total HE content in blood clam individual is power function of its body weight.
Arca subcrenata appears to have potential as an indicator of mercury contamination In BohaiGulf.
