Pesticide Residues in Passion Fruit and Assessment of Dietary Intake Risks
Objective To evaluate pesticide residues and dietary intake risks in passion fruit.Methods Ultra-performance liquid chromatography-mass spectrometry(UPLC-MS/MS)and gas chromatography-mass spectrometry(GC-MS/MS)were used to determine the pesticide residues in the whole fruit,peel and pulp of passion fruit sampled from six regions.The distribution differences of different pesticides in the whole fruit,peel and pulp of passion fruit were compared.The target hazard quotients(THQ)method was used to evaluate the dietary intake risk of the single pesticide residue,and the hazard index(HI)was used to evaluate the exposure risk of combined pesticide residues.Results Thirty-seven pesticides were detected,including nineteen kinds of insecticides,fifteen kinds of fungicides,two kinds of acaricides,and one kind of plant growth regulator.The detection rates of pesticides in whole fruit,peel,and pulp of passion fruit were 83.78%,94.59%,and 62.16%,with 33,35,and 23 residual pesticides detected.The THQ value of each single pesticide residue was less than 1.The HI value of the exposure risk of combined pesticide residues was 0.884 7.Conclusion Pesticide residues are common in passion fruit from six regions,but the overall risk is relatively low.The chronic dietary intake risk of passion fruit is relatively low,and the exposed population has no significant health risk.
