수입과일의 잔류농약 실태 및 위해성 평가 연구

Abstract

Pesticide residues in 96 samples of imported fruits selling at wholesale markets and traditional markets in Busan were monitored. Total 165 pesticides were analyzed by multi-residue method using gas chromatography/tandom mass spectrometer (GC/MS/MS). Samples were 30 citrus fruits, 45 tropical fruits, 18 were berry fruits, and 3 were stone fruits. The origin was 32 U.S.A. samples, 22 Philippine samples, 15 Chile samples, 8 Thailand samples, etc. Pesticide residues were detected in 45 samples(46.9 %) among 96 samples and a sample had violative residue. Detected pesticides were 14 chemicals, such as Fludioxonil, Imazalil, Chlorpyrifos, Tebuconazole, Cyprodinil, Iprodione, Myclobutanil, Phosmet, Buprofezin, Captan, Fenvalerate, Metrafenone, Pendimethalin and Procymidone. Most of the residual pesticides which were high in frequency are post harvest pesticides. Detected pesticides ingredient’s sample recoveries ranged from 79.58 to 119.29 %, relative standard diviation was 1.15∼7.54 %, LOD was 0.001∼0.053 mg/kg. LOQ was 0.003∼0.160 mg/kg. A risk assessment of pesticide residues in imported fruits was performed. The range of % ADI values was from 0.00002 to 0.46515 %.
