Excerpt
Excerpt: The bioavailability and toxicity of trace metals such as Cd, Cu, and Zn are related to the activity of the free metal ion rather than the total metal concentration (1- 5). For Cd it is the CdCl, complex that predominates in seawater (3). Therefore, salinity is the overriding factor which can alter free Cd ion activity {Cd2+}, and hence, bioavailability and toxicity in marine systems. Yet the relationships between {Cd2} in seawater and Cd bioaccumulation, metabolism, and toxicity are not well understood. We do know that the major mechanism underlying these relationships involves interactions between Cd and both membrane-bound and soluble ligands (6).
