Abstract: To investigate pesticide residues in commercially available vegetables in Hainan Province and evaluate the potential hazards of pesticide residues, 214 vegetable samples were collected from 18 cities and counties in Hainan Province from 2020 to 2022,33 pesticides were analyzed using liquid chromatography-mass spectrometry, and the risk index（R） and index of food safety（IFS） were calculated to evaluate the risks of pesticides to human health.The results showed that from 2020 to 2022, the pesticide residues detection items for commercially available vegetables in Hainan Province included 4 categories and a total of 33 items. A total of 23 pesticides were detected, with an average content of 0.001 2~0.049 6 mg/kg,the detection rate of pesticides was shown as follows： fungicides>insecticides>carbamates>organic phosphorus;among 214 vegetable samples, at least one pesticide （73.8%） was detected in 158 samples, and 6~9 pesticides were detected in fresh legumes and leafy vegetables. Celery and ordinary Chinese cabbage had the most coexisting pesticide residues, with 9 pesticides detected in both samples; the residual risk of 23 pesticides was evaluated using the risk coefficient method. Drosophilamine was evaluated as a high-risk pesticide, while carbofuran and 3-hydroxycarbofuran were evaluated as medium risk pesticides;according to the Food Safety Index Law, the index of food safety （IFS） of 22 other pesticides, except for Methomicide, ranged from 0.000 02 to 0.012 97, all of which were far less than 1.000 00. The risk of pesticide residues in vegetables in Hainan Province could be accepted by consumers;the risk assessment results indicated that the majority of residents in Hainan Province would not face health risks from consuming commercially available vegetables in Hainan Province, but further research was needed on the hazards of the combined use of multiple pesticides.
