본 연구에서는 2018년 충남에서 유통되는 과일류에 대한 잔류농약 실태를 조사하여 보고하고자 한다. 유통 과일류 150건을 실험대상으로 식품공전 다종농약다성분 분석법(제2법)으로 분석이 가능한 195종의 잔류농약을 실험 하였다. 150건의 과일 시료 중 63건에서 40종의 잔류농약이 검출되었으며, 검출률은 42.0%였다. 각 과일의 잔류농약 검출률은 감귤류(55.2%), 인과류(41.3%), 장과류(38.7%), 핵과류(36.0%) 순이였으며 표본이 작지만 열대과일에서는 잔류농약이 검출되지 않았다. 검출빈도가 높은 과일은 사과 21회, 감귤이 16회로 다른 과일에 비해 높은 검출빈도를 보였으며, 검출빈도가 가장 높은 농약은 bifenthrin(21회), pyraclostrobin(17회), novaluron(13회)로 나타났다. 잔류농약이 검출된 시료 중 74.6%의 시료에서 2종 이상의 동시에 검출되었다. 잔류농약이 검출된 63건의 과일 모두 잔류허용기준 이하로 안전한 수준으로 평가되었으나, 잔류농약 검출률이 높고, 농약의 종류가 다양해지고 있어 지속적으로 모니터링이 필요할 것으로 판단된다.

In this study, 195 pesticide residues in fruit samples (n=150) at local markets in Chungcheongnam- do Chungnam, Korea were monitored using a multi-residue method combined with GC-MS/MS and LCMS/ MS. Among 150 fruit samples, 40 types of pesticides were detected in 63 samples and the detection rate was 42.0%. However, the amounts were below the maximum residue limit (MRL). Detection rates for pesticides in each thpe of fruit were as follows ; citrus fruits (55.2%), pome fruits (41.3%), berries (38.7%) and stone fruits (36.0%). Although the sample size was small (n=2), pesticide residues were not detected in tropical fruits. Occurrences of detection of pesticide residues in apple showed the highest level, and mainly, insecticides were detected most frequently. The most commonly detected pesticides residues were bifenthrin (21), pyraclostrobin (17), novaluron (13), boscalid (10), chlorfenapyr (9), trifloxystrobin (9), furathiocarb (9), acetamiprid (8) and chlorpyrifos (8). Five types of residual pesticides (bifenthrin, chlorfenapyr, deltamethrin, fenpropathrin and fenvalerate) were detected in quince, and out of these five, fenpropathrin exceeded the MRL based on the Positive List System (PLS). These results suggested that pesticide residues in fruit samples should be continuously monitored, although residue levels in 63 other fruit samples were evaluated as being within a safe level.
