Popis:	ABSTRACTChinese onion is a common vegetable in daily diet, especially in Southwest China. We collected 184 samples from farm and market in Chongqing Municipality during 2020–2021 and established a multi-residue method for analysis of 79 pesticide residues on Chinese onion. Sixty-three of 184 samples were found pesticide resdues, accounting for 34.2%. A total of 31 pesticides were detected, and 6 pesticides in 11 samples have exceeded the Chinese MRLs, 5.98% of all samples. The chronic and acute dietary exposure assessment showed the %ADI and the %ARfD value were 0.005%–5.46% and 0.03%–297.95%, respectively. The %ARfD of most pesticides were acceptable except for cyhalothrin (297.95%, children; 140.17%, adults) and carbofuran (107.94%, children). The study indicated that pesticide residues on Chinese onion had different concentration levels which were low commonly. The establishment of MRLs for several pesticides (cyfluthrin, carbendazim, propamocarb) in Chinese onion is required for better estimation of dietary risk.
