Risk assessment of pesticide residues in peaches from Hebei province

Objective To determine thepesticide residue and risk level in peach from Hebei. Methods Totally 70 peach samples collected from Hebei province were detected. For the pesticides detected in the samples, acute and chronic dietary intake risks were assessed and the pesticide risks were ranked by the matrix ranking. Results It was showed that 100% of the peach samples had detectable residues and 33 kinds of pesticide residues were detected. Some pesticide residues in samples were over standard, such as polymycorrine and methylamabamectin benzoate. For the pesticides with detectable residues, the chronic dietary intake risks expressed as%ADI (acceptable daily intake, ADI) were 0.00%?1.06%, and the acute dietary intake risks expressed as%ARfD (acute reference dose, ARfD) were 0.00%?11.33%. According to the risk score, there were 5 high risk pesticides, among which chlorpyrifos (45.7%) and methylamabamectin benzoate (18.6%) had higher detection rates. Conclusion The detection rates of pesticide residues in peach samples from Hebei are relatively high, while 94.3% of the samples are under maximum residue limits (MRLs). Both chronic and acute dietary intake risks of pesticide residues in peach samples are very low. Among them, carbendazil, chlorpyrifos and methylamabamectin benzoate are the risk factors that should be paid attention to in peach.
