Residual levels and dietary intake risk assessment of 11 pesticides in apricots from different ecological planting regions in China.

ABSTRACT: The frequent and massive use of pesticides has led to pesticide residues in apricot, threatening food safety and human health. A reliable and simple modified QuEChERS method with ultra-performance liquid chromatography-tandem mass spectrometry was developed for the simultaneous determination of 11 pesticides in apricot. Method validation indicated that satisfied linearity (R² ≥ 0.9959), accuracy (recoveries of 72-119%), sensitivity (limits of detection, 0.03-0.30 μg/kg; limits of quantification, 0.13-1.00 μg/kg), and precision (relative standard deviations ≤ 11.9%), and matrix effects were 0.89-1.13. Apricot samples from different ecological regions in China were collected and tested using the proposed methods. Monitoring results were used to assess the dietary intake risk of Ch
