  • The purpose of this study was to investigate 253 kinds of pesticide residues in 58 commercial dried agricultural products in Seoul. The determinations of the pesticide residues were performed using multiresidue methods and were carried out by a gas chromatography-nitrogen phosphorus detector (GC-NPD), an electron capture detector ($GC-{\mu}ECD$), a mass spectrometry detector (GC-MSD) and high performance liquid chromatography-ultraviolet detector (HPLC-UV), and a fluorescence detector (HPLC-FLD). The pesticide residue detection rate in the commercial dried agricultural products was 24.1% (14 of 58 samples). Twelve pesticide residues without maximum residue limits (MRLs) were detected. In the vegetable groups, the frequency of pesticide residues was found to be in the increasing order of dried fruiting vegetables > dried leafy vegetables > dried stalk and stem vegetables. The pesticides used on dried red pepper in the dried fruiting vegetables were varied (7 kinds) and numerous (4 of 8 samples). The pesticide types detected in the commercial dried agricultural products were in the order of pyrethroid > organochloride > organophosphorus and insecticide > fungicide > herbicide ${\cdot}$ nematicide. The primary pyrethroid pesticide detected was cypermethrin. According to the producing areas of products, large numbers of pesticide residues were found in the order of Korea, China, North Korea, USA, and Vietnam.

  • Pesticide residues were monitored in agricultural products purchased at Gyeongin and Jeolla-do provinces. Total 245 pesticides were analysed by GC-MS and LC-MS/MS, and residual pesticides were detected in 70 samples (19.7%), with spinach and chard showing high detection frequency of 35%. Fifteen samples (4.2%) exceeded Korea Maximum Residue Limits (MRLs), and 30 types of pesticides were detected in samples with azoxystrobin, procymidine, endosulfan showing considerably high frequencies in respectively 14, 13, and 13 samples. The amount of 11 pesticide including chlorpyrifos, indoxacarb among them were detected over Korea MRLs. No residual pesticides were detected in 285 (80.3%) samples, and residual pesticides levels of 55 samples (15.5%) were lower than Korea MRLs, indicating 95.8% samples were relatively safe.

  • In this study, 195 pesticide residues in fruit samples (n=150) at local markets in Chungcheongnam-do Chungnam, Korea were monitored using a multi-residue method combined with GC-MS/MS and LCMS/MS. Among 150 fruit samples, 40 types of pesticides were detected in 63 samples and the detection rate was 42.0%. However, the amounts were below the maximum residue limit (MRL). Detection rates for pesticides in each thpe of fruit were as follows ; citrus fruits (55.2%), pome fruits (41.3%), berries (38.7%) and stone fruits (36.0%). Although the sample size was small (n=2), pesticide residues were not detected in tropical fruits. Occurrences of detection of pesticide residues in apple showed the highest level, and mainly, insecticides were detected most frequently. The most commonly detected pesticides residues were bifenthrin (21), pyraclostrobin (17), novaluron (13), boscalid (10), chlorfenapyr (9), trifloxystrobin (9), furathiocarb (9), acetamiprid (8) and chlorpyrifos (8). Five types of residual pesticides (bifenthrin, chlorfenapyr, deltamethrin, fenpropathrin and fenvalerate) were detected in quince, and out of these five, fenpropathrin exceeded the MRL based on the Positive List System (PLS). These results suggested that pesticide residues in fruit samples should be continuously monitored, although residue levels in 63 other fruit samples were evaluated as being within a safe level.

  • 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%.

  • 제 2차 세계대전이 끝난 후 전 세계의 인구는 경제발전과 함께 폭발적으로 증가하였고, 인류는 "식량증산"이라는 새로운 현실에 부딪히게 되었다. 그리고 1960년대 이후 현대농업에 있어서 화학기술의 발전으로 탄생한 현재의 농약은 획기적인 생산성 향상으로 식량의 자급자족과 소득증대를 가져오는데 일익을 담당한 필요불가결한 농자재가 되었다. 그러나 현재의 농약은 식량 생산증대에 큰 도움을 주었지만, 농작물에 잔류하는 농약의 잔류독성으로 인한 폐해로 인해 부정적인 측면도 함께 가지게 되었다. 잔류농약의 치명적 위협은 지금 전 세계를 혼란케 하는 발암물질인 다이옥신으로 인해 극명하게 밝혀진 바 있다. 내분비계 교란물질인 환경호르몬의 대표격인 다이옥신의 원인물질 67종 중 41종이 농약성분이기 때문이다.
