闽江福州段河蚬体内的重金属含量

HEAVY METAL LEVELS IN CLAM (CORBICULA FLUMIN-EA) FROM MINJIANG RIVER, FUZHOU AREA

1987年我们系统地调查分析了闽江福州段河蚬(Corbicula fluminea M(?)ller)体内7种重金属的含量,希望为全面评价闽江水体质量,并为开发利用闽江河蚬资源提供参考资料。

The contents of Cu, Pb, Cd, Ni, Cr, Hg and As in soft part of clam (C. fluminea) from Minjiang River, Fuzhou area were determined by using atomic absorption spectrophotometer. The results obtained indicate that the metal levels determined are not very high in the clam except Pb and Cr which usually exceed the permissible limit for human food. The metal contents in the clam are varied with sampling sites. Higher contents always appear near the source of pollution which are coincident with the metal contents in the sediment. This clam is one of the useful indicator organisms for heavy metal monitoring in the Minjiang River.
