摘要：It is crucial to evaluate the levels of pesticide amounts to identify adverse health effects and po-tential risks of pesticides on at-risk practitioners prospectively. This study aims to determine the level of pesticide exposure among pesticide opera-tors in citrus orchards. In this respect, five patches were attached to the skin(ACE) and clothing (OCE)of each operator (right arm, left arm, right leg, left leg, and chest). The amounts of pesticides in the patches were analyzed by LC-MS/MS method, and risk assessment was made regarding the concentra-tions in these patches. Ten different pesticides were detected on the applicators, which were Cymoxanil, Boscalid, Difenoconazole, Abamectin, Chlorpyri-fos-ethyl, Chlorpyrifos-methyl, Propiconazole, Pyraclostrobin, Pyriproxyfen and Buprofezin. Analysis of patches placed over-the-clothing and under-the-clothing showed that the average amount of pesticide residue over-the-clothing was higher than the residue detected under-the-clothing. High levels of Chlorpyrifos-methyl exposure were ob-served in over-the-clothing. The study results show that special clothing, called personal protective equipment, must be worn over daily clothing while spraying.
