Abstract

BACKGROUND: This study was conducted to monitor the current status of pesticide residues and to assess their risk in domestic agricultural products. The samples were rice, barley, lettuce and perilla leaf. These four types of agricultural products were those with GAP(Good Agricultural Practice) certification, organic agricultural products, pesticide-free agricultural products or general agricultural products. METHODS AND RESULTS: They were purchased from traditional markets and supermarkets of 12 regions in Korea from July to August 2010. The total number of samples was 259 for agricultural products and these were analyzed by GC/ECD, GC/NPD and GC/MSD. We used multiresidue methods to analyze for 110 different pesticides except for herbicides. CONCLUSION: In this study, residual pesticides were detected in 18 samples. Among these general agricultural products, organic agricultural products and products with GAP-certification were detected in 12, 4 and 2 samples, respectively. Detection rates of general agricultural products, organic agricultural products and products with GAPcertification were 4.6%, 1.5% and 0.8% respectively. Pesticides were not detected in pesticide-free agricultural products. Their detection levels were less than their maximum residue levels. Their estimated daily intakes ranged from 0.0003% to 0.04302% of their acceptable daily intakes, of which the values have no effect on human health.

유통되고 있는 관행농산물, 유기농산물, 무농약 농산물 그리고 GAP인증농산물 가운데 곡류(쌀, 보리)와 엽채류(상추, 들깻잎)의 농약잔류실태와 안전성을 평가하기 위하여 12개의 지역의 백화점, 대형마트 및 재래시장에서 농산물을 구입하여 총 259점을 분석하였다. 분석결과 잔류농약의 검출율은 일반 농산물에서 4.6%, 유기농산물에서 1.5%, 무농약농산물에서 0% 그리고 GAP인증농산물에서 0.8%이었다. 보리 시료 63점에서는 잔류농약이 검출되지 않았고, 쌀 시료 69점에서는 isoprothiolane이 3점 검출되어 4.3%의 검출율을 보였다. 상추 시료 64점에서는 cypermethrin이 2건 검출되어 3.1%의 검출율을 보였으며 들깻잎 시료 63점에서는 dichlorvos가 13건 검출되어 20.6%의 검출율을 보였다. 검출된 농약들은 모두 잔류허용기준 미만으로 나타났으며 검출농약이 해당 농산물의 섭취로 인체에 유입될 잔류농약의 1일추정섭취량을 산출한 결과 ADI의 0.0003~0.04302% 수준이었다. 검출된 농약이 MRL 이하로 나타났거나 %ADI가 낮다고 하여 안전하다고 사료되지만 유기농산물인 들깻잎에서 농약이 검출된점 그리고 상추에서 검출된 cypermethrin은 해당작물에 대한 안전사용기준이 설정되어 있지 않기 때문에 문제가 있는 것으로 나타났다.
