Abstract:

The paper discussed accumulation of heavy metals in the digestive glands and gills of Ruditapes philippinarum with single or combined exposure of zinc and lead and relationship between MT (metallothioneinm) induction and accumulation of heavy metals. Results indicated that the antagonistic effect of znic and lead was obvious in clam jointly exposed to zinc and lead (Zn2+ 50μg/L and Pb2+ 25μg/L). MT varied with exposure concentrations of zinc and lead and the effect of lead was significant.

Key words: heavy metals, metallothioneinm, joint toxicity, antagonistic effect
