초록

청주지역 유통 엽채류 중 농약잔류실태를 파악하기 위하여 2010년 6월과 8월 두 차례에 걸쳐 청주농수산물도매시장과 재래시장에서 상추 등 15종 엽채류 총 180점을 채취하여 103종의 농약을 대상으로 GC-ECD/NPD와 HPLC-DAD/FLD를 이용한 다성분 동시분석법으로 잔류농약을 분석하였다. 180점의 농산물 중 12점에서 7종의 농약이 검출되었으며, 검출율은 6.7%이었다. 6월에 채취한 시료에서는 근대를 포함한 6종의 농산물에서 tefluthrin 등 5종의 농약이 검출되었으며, 8월에 채취한 시료에서는 취나물을 포함한 3종의 농산물에서 pendimethalin 등 3종의 농약이 검출되었다. 검출농약 중 잔류허용기준을 초과한 농약은 재래시장의 쑥갓에서 검출된 azoxystrobin 1종으로 잔류허용기준 초과율은 0.6%이었으며, 취나물에서 검출된 azoxystrobin과 부추에서 검출된 tefluthrin을 제외한 모든 검출농약은 해당 작물에 잔류허용기준이 설정되지 않은 농약이었다. 엽채류에서 검출된 농약의 일일섭취허용량은 일일섭취추정량의 7% 미만으로 안전한 것으로 판단되었다.

영어초록

In order to monitor the residual characteristics of the pesticides in leafy vegetables selling at wholesale markets and traditional markets in Cheongju, a total of 180 samples of 15 leafy vegetables, such as broccoli, celery, chard, chicory, Chinese vegetable, Chwinamul, crown daisy, Korean cabbage, leek, lettuce, perilla leaves, Shinsuncho, spinach, welsh onion and young radish, were purchased from the wholesale markets and traditional markets in June and August in 2010 and the pesticide residues in them were analyzed by multiresidue analysis method using GLC, HPLC and GC-MSD. Seven pesticides were detected from 12 samples out of total 180 samples collected, representing detection rate was 6.7%. In case of the samples collected from markets in June, four pesticides including tefluthrin were detected from six samples and in case of the samples collected from markets in August, three pesticides including pendimethalin were detected from three samples. The MRL-exceeding rate of pesticides detected from leafy vegetables was 0.6%. The pesticide exceeded its MRL was azoxystrobin detected from crown daisy and many pesticides were not registered to the crops, excepting that azoxystrobin detected from Chwinamul and tefluthrin from leek. Estimated daily intakes (EDIs) of the pesticides detected from leafy vegetables were less than 7% of their acceptable daily intakes (ADIs), representing that residue levels of the pesticides detected were evaluated as safe.
