Abstract Objective To explore the regularity and characteristics of pesticide poisoning in Zhejiang Province and to provide scientific basis for pesticide poisoning prevention. Methods The cases of pesticide poisoning in Zhejiang Province from 2007 to 2016 were collected through the occupational diseases and occupational health information monitoring system. The district,types of pesticides,time,gender and age of poisoning were analyzed. Results There were 46 671 cases of pesticide poisoning in Zhejiang Province from 2007 to 2016,14.91% of which were productive exposure poisoning,while 85.09% were non-productive exposure poisoning. There were 2 735 death cases,so the fatality rate was 5.86%. There was no obvious change trend in the mortality rate of productive poisoning（P>0.05）,which was 0.88%. The mortality rate of non-productive poisoning was much higher,which was 6.73%（P<0.05）,with a decreasing trend in this decade（P<0.05）. The pesticide poisoning occurred more from July to September than other months,with a total number of 16 806 cases,which was 36.01% of the 46 671 cases. Hangzhou,Taizhou and Huzhou reported the largest number of cases. The number of organophosphorus pesticide poisoning cases was the highest,accounting for 56.89% of the total poisoning cases. The highest incidence of poisoning was among 35-64 years old ones 51.44% of the cases）. The number of death cases in groups older than 75 years was the largest,accounting for 11.44% of the total number of deaths. The cases of suicide poisoning accounted for 77.07% of non-productive pesticides poisoning,and the fatality rate was 8.11%. The mortality rate increased with age（P<0.05）. The mortality rate of suicide poisoning in male patients was 9.82%,which was higher than that of female（6.59%）（P<0.05）. Conclusion The pesticide poisoning in Zhejiang Province is mainly caused by non-productive self-service poisoning. The mortality rate of pesticide poisoning in the elderly population is high.
