Study on environmental risk assessment of carbendazim on wheat and rice in China
According to the requirements of"Guidance on Environmental Risk Assessment for Pesticide Registration",the risks of carbendazim to terrestrial ecosystems,groundwater and aquatic ecosystems in the control of scab of wheat and sheath blight of rice were assessed,respectively.The results showed that the long-term risk of carbendazim to birds,the risk of peripheral mulberry leaves to silkworm and predatory non-target arthropods in farmland were unacceptable in terrestrial ecosystem,and there was no risk to groundwater.Therefore,some appropriate risk reduction measures could be taken to ensure the safety of carbendazim in wheat.After carbendazim was applied on rice,the risk components to vertebrates and invertebrates accounted for 100％of the simulation group,and the risk component of carbendazim to primary producers accounted for 6.90％of the simulation group,respectively.Carbendazim had high risk to aquatic ecosystem.Therefore,the registration of carbendazim on rice should be reexamined in the process of reevaluation.
