Cadmium, iron, and zinc uptake individually and as a mixture by Limnodrillus hoffmeisteri and impact on adenosine triphosphate content.

abstract：:Metal mixture toxicity has been studied for decades. However, the results are not consistent, and thus ecological risk assessment and regulation of mixtures has been difficult. The objective of the present study was to use a systematic experimental design to characterize the toxicity of binary-metal mixture of Cu, Zn,...
