Concentration-dependent interactive toxicity of cadmium and mercury: Non-negligible effects on phytoremediation by indigenous Artemisia lavandulaefolia.

The indigenous species Artemisia lavandulaefolia, widespread in areas co-contaminated with Cd and Hg, has the potential for phytoremediation. However, the mechanisms that underlie these plants' resistance to combined Hg and Cd stress are unelucidated. The influence of the dosage of one metal on another has also not been adequately quantified.
