Abstract:
To clarify the residue behavior and possible dietary risk of abamectin in fresh corn, bitter melon, and Fritillaria , a method was developed for the simultaneous determination of abamectin residues in fresh corn, bitter melon, and Fritillaria by QuEChERS ( qu ick, e asy, ch eap, e ffective, r ugged, s afe) ultra‐performance liquid chromatography–tandem mass spectrometry. The mean recovery of abamectin in fresh corn, bitter melon, and Fritillaria was 86.48%–107.80%, and the relative standard deviation was 2.07%–10.12%. The detection rates of abamectin residues in fresh corn, bitter melon, and Fritillaria were 62.50%, 87.50%, and 80.00%, respectively. The residues of abamectin in fresh corn, bitter melon, and Fritillaria were not more than 0.020, 0.019, and 0.087 mg/kg, respectively. Based on these results, dietary risk assessment showed that the risk content of abamectin residues in long‐ and short‐term dietary exposure for Chinese consumers was 61.57% and 0.41%–1.11%, respectively, indicating that abamectin in fresh corn, bitter melon, and Fritillaria in the market would not pose a significant risk to consumers.
