본 연구에서는 들깨 시설재배지 토양 및 작물 중 잔류성유기염소계 농약의 잔류량을 조사하였다. 토양 및 작물 중 잔류성유기염소계 농약 분석을 위한 추출 및 정제는 QuEChERS 방법을 다소 개선한 방법으로 수행되었다. 들깨 시설재배지 토양 및 농산물 중 잔류성유기염소계 농약의 회수율은 각각 76.3-113.4 및 79.4-107.3%, 정량한계는 각각 0.03-0.24와 <TEX>$0.33-0.50{\mu}g/kg$</TEX> 수준이었다. 들깨 시설재배지 토양에서 dieldirn 및 endosulfan sulfate 2 성분만이 각각 1.6-9.2 및 <TEX>$22.0-87.8{\mu}g/kg$</TEX> 수준으로 검출되었으나 들깻잎의 모든 시료에서는 검출되지 않았다. 이러한 결과는 들깨 시설재배지 토양이 농산물 안전성을 위협할 정도로 잔류성유기염소계 농약으로 오염되지 않았음을 나타냈다. This study was conducted to investigate residual organochlorine pesticides in green house soil and green perilla leaves. Extraction and clean-up method were developed using the modified QuEChERS method for residual organochlorine pesticides (ROCPs) in soil and green perilla leaves. Recovery and limit of quantitation (LOQ) of ROCPs in greenhouse soil and green perilla leaves were 76.3-113.4 and 79.4-107.3%, 0.03-0.24 and <TEX>$0.33-0.50{\mu}g/kg$</TEX>, respectively. Detected ROCPs in greenhouse soil were dieldrin and endosulfan sulfate, the residue were 1.6-9.2 and <TEX>$22.0-87.8{\mu}g/kg$</TEX>, respectively. But two pesticides in all green perilla leaf samples were not detected. These results showed that ROCPs residue in greenhouse soil was lower than the level of bioaccumulation occurring.
