Abstract

Monitoring of pesticide residues were conducted at three sites in the Southern Area of Seoul, Korea (Gang-nam, Gang-dong and Song-pa). We measured pesticide residues within soil samples using multi-pesticide residues analysis. Samples were collected at the three sites with 60 sampling spots. The amount of pesticide residues in the soil samples were as follows [(minimum-maximum), mg/kg] endosulfan 0.002-0.999, procymidone 0.002-1.200, diazinon 0.003-0.024, metalaxyl 0.012-0.075. In soil treated with 0.445 mg/kg of endosulfan, the pesticide absorbed by chamnamul, was 0.157 mg/kg (Absorption rate : 35.3%). However, in soil treated with 0.358 mg/kg of endosulfan, the pesticide absorbed by lettuce, was 0.004 mg/kg (Absorption rate : 1.1%).

본 연구는 강남일부(강남구, 강동구, 송파구)지역 시설재배지에서 시기별 잔류농약의 오염 실태를 파악하고자 하였다. 각 지역에서 2010년 4월부터 2011년 6월까지 토양시료 60 점을 채취하여 시료 중 농약 잔류량을 다성분 동시 스크리닝 분석법으로 분석하였다 시설재배지 잔류농약 조사결과, endosulfan 0.002-0.999 mg/kg, procymidone 0.002-1.200 mg/kg, diazinon 0.003-0.024 mg/kg, metalaxyl 0.012-0.075 mg/kg로 검출되었다. 시설재배지 토양의 잔류농약 모니터링 결과 검출빈도가 높게 나타난 endosulfan을 대상으로 참나물, 상추에 대하여 흡수 이행 정도를 조사하였다. 강남구 지역의 토양에서 잔류농약을 검사한 결과 endosultan이 0.445 mg/kg로 잔류하였고, 이 토양에서 참나물을 60일 재배 후 잔류농약 검사를 실시한 결과 endosulfan 0.157 mg/kg로 잔류하여 토양 대비 참나물 중 endosulfan 이행률은 35.3%를 보였다. 또한 강동구 지역의 토양에서 잔류농약을 검사한 결과 endosulfan이 0.358 mg/kg로 잔류하였고, 이 토양에서 상추를 60일 재배 후 상추 중 잔류농약 검사를 실시한 결과 endosultan 0.004 mg/kg로 잔류하여 토양 대비 endosulfan 이행률은 1.1%를 보였다.
