Human pharmaceuticals in the marine environment: Focus on exposure and biological effects in animal species.

abstract：:To develop a multimetal toxicity model requires insight into the relationships between the composition of metal mixtures and their toxicological effects on organisms. As a first step in developing such a model, quantitative data from binary and higher mixture studies of Cu, Cd, and Zn were compiled and used to assess ...
