The results showed that the detectable rate of pesticide was 55.56%, and the pesticide detectable rate of samples was 59.09% in red bayberry. The exceeding standard rate of pesticides was 15.87%. In terms of safety index, the risk and safety state of all pesticides were within an acceptable range except cyhalothrin. In terms of risk coefficient, omethoate, triazophos and isocarbophes were at high-risk state, and the remaining 19 kinds of pesticides were at low-risk state.展开更多
