  • 최근, 무분별한 농약사용으로 인해 조리 후에도 잔류하는 농약성분의 독성이 문제시 되고 있어 인체 내로의 섭취 전에 독성 유무와 그 정도를 확인할 수 있는 방법 개발을 위한 연구가 활발히 진행되고 있다. 본 연구에서는 채소류, 곡류, 과일류 등에 빈번히 사용되는 농약성분의 독성 확인과 함께 이들 식품 내에 잔류하는 농약성분의 검출을 위한 방법을 연구하였으며, 이들의 독성 유무를 유전자 재조합된 5종의 발광성 미생물을 이용하여 확인하였다. 또한 이들 농약류가 식품 내에 잔류하여 발생하는 독성을 분석하기 위해 식품내 잔류하는 농약 성분의 추출에 필요한 효율적인 추출 용매를 제작하였으며, 농약성분의 화학적 성질에 따라 추출 방법을 두 단계로 분리하여 추출률을 향상시켰다. 뿐만 아니라, 식품류의 특성에 적합하게 식품별로 특정한 추출방법을 연구하였으며, 추출된 농약 성분의 독성 및 안정성 역시 발광성 박테리아를 이용하여 확인하여, 전체적인 추출방법의 효율을 진단하였다.

  • This survey was carried out in 2014 to estimate the pesticide residue levels in commercial environment-friendly agricultural products in Seoul metropolitan area. Pesticide residues in 27 commodities were examined and analyzed using LC-MS/MS, which can simultaneously detect up to 85 pesticides. A total of 441 samples were collected and analyzed. Among the detected samples, the residue levels in 1.2% of organic agricultural products and 2.2% of pesticide-free agricultural products exceeded the maximum residue limits (MRLs); hence, 1.8% of the total samples exceeded the MRLs. The safety of the detected pesticides was assessed by monitoring the acceptable daily intake level (ADI) and acceptable dietary exposure (ADE) to the pesticides via consumption of the commodities. ADI and ADE are found to be 0.07728-9.46530% and 0.00141-0.17210%, respectively, which means that the residual pesticides in the environmental-friendly agricultural products in Korea are below the safe limit and therefore, pose no potential public health risks.

  • The purpose of this study is to the distributive property of organic pollutants in effluents of domestic sewage treatment plants around Youngsan River using simultaneous analysis method of 310 chemicals. The numerous organic pollutants were detected in five sampling sites, and the major chemicals were pesticides, CH type chemicals such as benzenes and polycyclic compounds, ande CHO type chemicals such as phenols and phthalates. About 14 pesticides were detected in the effluent and most of them were found in summer. 1-Chlorobenzen and p-octylphenol were frequently detected in the concentration range of $0.52{\sim}0.61\;{\mu}g/L$ and $0.04{\sim}0.89\;{\mu}g/L$, respectively. Moreover, 18 kinds of endocrine disrupters include diethylphthalate were detected in effluents. From the results of this study, therefore, we confirmed that the pesticides, CH and CHO type chemicals in domestic effluents throughout Youngsan River are required specific regulation.

  • 최근에 과수농가의 농민과 원예 및 능금조합의 지도기사들을 대상으로 과수해충 방제실태에 대한 설문조사를 한 결과, 사과원에서는 응애류가 심식충류나 진딧물보다 방제가 어려운 해충으로 지적되고 있다. 또한 필자가 전국 6개 지역의 15개 일반 농가의 사과원을 2년간 년 3회 이상 관찰한 결과에서도 심식충류의 피해를 받고 있는 농가는 거의 없었으며, 응애류는 그 발생정도에 차이는 있으나 대부분의 사과원에서 상존하고 있는 현상이었다. 이와 같이 응애류가 사과원에서 주요해충으로 등장하게 된 이유는 첫째, 시비$\cdot$농약살포 등 관리상태의 향상으로 사과나무 잎의 생리적 조건이 변화되어 응애류의 생식력을 자극시켰기 때문이라는 ''생식자극설''(生殖刺戟設)과 둘째, 1940년대 후반 이후 농약 사용의 급증으로 인하여 응애류의 발생을 억제하던 포식성 응애를 비롯한 천적류가 감소 또는 멸종되었기 때문에 응애류가 격발(激發)하게 되었다는 ''포식자억제설''(捕食者抑制設) 등이 있다.

  • This paper specifically discusses the risk assessment on the pesticide residues in vegetables collected from traditional markets, big marts and departments in the southern part of Seoul. Vegetable samples were 6,583 cases from January to December in 2009. Monte-Carlo simulation was used to calculate the uncertainty for the risk index using pesticide residues, average dietary intake for vegetables and acceptable daily intake. Deterministic risk indexes were 7.33% of diethofencarb, 5.13% of indoxacarb, 3.96% of EPN, 3.92% of diniconazole and 3.09% of chlorothalonil, respectively. And other pesticides were below 3%. Distributions of risk indexes obtained by the Monte-Carlo simulations were similar to the deterministic values, even though the confidence intervals for 95% were very wide. We confirmed that health risks caused by eating vegetables exceeded maximum residue limits of pesticide are very low and the population is generally safe, judging from the risk indexes located between 0.07 to 9.49%.

  • Comparison of pesticide residue dissipation in/on cucurbitaceous fruit vegetables applied by foliar spraying under greenhouse was carried out to give information on crop grouping for assessment of pesticide risk. Even though the initial deposit of spayed pesticide on the target vegetables were somewhat different from the varieties, the dissipation patterns of the residues gave a similar tendency. In case sub-groupings of cucurbitaceous fruit vegetables are carefully arranged, the residue data among the vegetables are able to be taken for pre-harvest interval (PHI) settings or food safety assessment.

  • In order to monitor the residual pesticides in environment friendly agricultural commodities, fruits and fruiting vegetables. Twenty-five agricultural commodities were collected twice in May and August 2011 from nine environment friendly agricultural commodities-selling supermarkets and retail stores located in eight major cities in Korea. The number of each agricultural commodity collected, 555 samples in total, was 152 organic agricultural products, 202 pesticide-free agricultural products and 201 low-pesticide agricultural products. Pesticide residues in samples were analyzed by multiresidue method for 245 pesticides using a GC-ECD/NPD and an HPLC-DAD/FLD and the peaks suspected as pesticides were identified with a GC/MSD. As a result of pesticide residue analysis, three pesticides, bifenthrin, EPN and chlorpyrifos, were detected from four samples including apple, representing a detection rate of 0.72%. The residue levels of the four pesticide-detected samples were less than their maximum residue limits (MRLs) but one pesticide EPN detected from pear exceeded its legible criterion of one twentieth MRL. Estimated daily intakes of the pesticides detected from fruits and fruiting vegetables were less than 0.76% of their maximum permissible intake.
