The Structure of Environmental Background Value of Cadmium in Jiaozhou Bay Waters

Abstract

Sources of heavy metals in marine environment could be cagetoried as natrual source and artificial source. The portion from natrual source forms the environmental background value of heavy metal. This paper proposed the theory of the structure of environmental background value for heavy metal. Finally, this paper applied this theory in the analysis of the environmental background value of Cadmiun (Cd) in Jiaozhou Bay waters. This theory provides basis for pollution control and remediation of marine environment.
