국내 유통 농산물 16품목을 대상으로 LC/MS/MS로 분석 가능한 다종다성분 농약 60종을 검사하여 식품의 잔류농약 안전성을 조사하였다. 조사대상 농산물 510건 중 대부분의 농산물인 490건(96.1%)의 농산물은 농약이 검출되지 않았으며, 18건(3.5%)의 농산물에서 농약이 검출되었으나, 대부분 잔류허용기준 미만으로 검출되었다. 들깻잎, 부추 등 엽채류의 검출빈도가 높은 편이었으나 대부분 잔류허용기준 미만으로 검출되었고, 시금치, 부추에서 각각 ethaboxam, fluquinconazole이 잔류허용기준 이상으로 검출되었다. 검출 농약은 9종이었으며, azoxystrbin과 dimethomorph가 가장 많이 검출되었다. 쌀 등 16품목의 다소비 농산물을 대상으로한 모니터링 결과 농약의 잔류량은 대부분 잔류허용기준 미만으로 비교적 안전한 수준으로 농산물에 대한 농약 관리가 이루어지고 있는 것으로 판단되었다. This survey was carried out to estimate pesticide residue levels in commercial agricultural products in the year 2009. Residues were examined in 16 commodities (rice, foxtail millet, buckwheat, kidney beans, peanuts, sesame, oranges, grapefruit, kiwifruit, spinach, perilla leaves, leeks, garlic stem, garlic, ginger, and oak mushroom) collected from 22 provinces in Korea. Analyses were performed by multi-methods capable of detecting up to 60 pesticides by LC/MS/MS. A total of 510 samples were collected and analyzed. Of the samples, 96.1% contained no detectable pesticide residues. Detectable residues at or below the MRLs were found in 3.5% of the samples. However, in 0.4% of the samples (spinach and leeks), residue (ethaboxam and fluquinconazole) levels exceeded the MRLs. Furthermore, intake assessments of 7 kinds of pesticide residues were carried out, excluding those exceeding the MRLs. The results showed that the ratios of EDI (estimated daily intake) to ADI (acceptable daily intake) were 0.0001-0.0006%, which indicates that the detected pesticide residues were in a safe range. It is concluded that residual pesticides in agricultural products are properly controlled in Korea.

소고기와 우유에서의 잔류농약 다성분분석을 위한 GC-MS/MS 분석 및 QuEChERS 전처리 방법의 검토

Bovine meat and milk are predominant food resources that are consumed by a large portion of the population in the world. Pesticides are commonly used on animal feed and they could be accumulated in animal tissues and other animal-derived foods like milk. To prevent the unnecessary exposure of consumers to pesticides, the determination of pesticide residues in bovine meat and milk is important. However, analyzing pesticide multi-residues in livestock is challenging due to a large amount of lipid and fats as well as the matrix-complexity of animal tissue. Here, we present the initial results of method development for the determination of 127 pesticides using GC-MS/MS. The multiple reaction monitoring transitions were optimized to allow simultaneous quantitation and identification. Sample preparation and clean-up were based on the modified QuEChERS methods. Initial results indicate that extraction with acetonitrile without other acid gave desirable performances in view of the simplicity of the method. Several combinations of the clean-up absorbents and cartridges including C18, PSA, Prime HLB, Captiva EMR-Lipid were compared in terms of recovery rate and repeatability. Further optimization of the sample preparation method and validation of the optimized method is needed for obtaining accurate and reliable data.
