| Abstract: | This paper proposed the single factor and integrated method for risk assessment of pesticide application. The assessment factors including: dosage, acute and chronic toxicity, mutagenesis, carcinogenesis and deformation, half-life of degradation in crops and soil. toxicity to fish and bee, irritation to skin and eye. The additional factors including: evaporation, toxicity of metabolite, coefficient of biological concentration and toxicity of herbicide to following crops. The assessment focused on dosage, acute and chronic toxicity of pesticides which widely used in China. |
