Outline
To assess the levels of pesticide residues in vegetables in Jiamusi City from 2023 to 2024 and their dietary intake risks.
Quantitative detection of 38 kinds of pesticide residues in 90 vegetable samples collected from farmers’ markets and supermarkets was conducted by gas chromatography-mass spectrometry and high performance liquid chromatography-mass spectrometry. Chronic and acute dietary intake risk assessments were conducted for detected pesticides.
The detection rate of pesticide residues in vegetables was 63.33%.Cyfluthrin, propafenil, carbendazim and triadimefon were the main detected pesticides. Among different categories, leafy vegetables were high-risk types of vegetables. Chronic and acute dietary intake risk assessment indicated that the acceptable daily intake% (ADI%), acute reference dose% (ARfD%) and index of food safety (IFS) of various pesticides were all below the safety threshold and the overall risk was controllable.
The study confirms that there are certain pesticide residues in vegetables in Jiamusi City. Although the overall dietary intake risk is acceptable, it is necessary to strengthen the supervision of high-risk pesticides, optimize the monitoring system and promote differentiated management.
