The nonlocal red bayberry sold in Cixi City were quantitatively analyzed for consecutive four years from 2010 to 2013,in order to understand their pesticide pollution. 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 isocarbophos were at high-risk state,and the remaining 19 kinds of pesticides were at low-risk state.
