Research Advancement of the Joint Toxicity of Heavy Metals Mixture

Some researches on heavy metals treatment and disposal methods have been reported, the studies related to the single heavy metal toxicity are developed, but the relatively on toxicity of multi-compounds heavy metals and their mixture have been poorly discussed. This article describes the levels of single heavy metals, compares the strengths and weaknesses of diferent test methods, emphasizes on the characteristics of joint toxicity with mixture. The analysis results discover that the combined toxicity of heavy metals vary with different mixtures combinations, test target, methods and some predictive models were adopted to determine the dose-effect relationship. which propose the development direction of heavy metals toxicity, provide theoretical support for the establishment of environmental monitoring and evaluation methods system.
