A Review on the Toxicity of Heavy Metal Pollution to Anura

Based on lots of relative research data in the last 20 years,the effects of heavy metal pollution on Anura were summarized in this paper. Test animals and test methods were introduced,major phenomena of heavy metal injury on shape,organs,tissues,cells and at the molecule level to Anura were summed up. The impact factors and major mechanism of heavy metal toxicity to Anura were analyzed preliminarily from perspectives of the process of the induced poison,environmental factors,species,development,heavy metal accumulation,joint toxicity and so on,and some responses of anti-toxicity or detoxification or evading toxicity in Anura to heavy metals were concluded. Several proposals for further research were put forward.
