내분비계 장애를 일으킬 수 있다고 추정되는 물질로는 각종 산업용 화학물질, 살충제와 제초제 등의 농약류, 유기 중금속류, 소각장의 다이옥신류, 식물에 존재하는 식물성 에스트로겐 (phytoestrogen) 등의 호르몬 유사물질, DES (diethylstilbestrol) 등의 합성 에스트로겐류 및 기타 식품, 식품첨가물 등이 포함된다. 이와 같은 물질들은 생물들에게 독성을 나타내므로 많은 나라들은 그 사용을 금지하거나 제한하고 있는 실정이다. (중략)

We investigated five neonicotinoid pesticide residues (acetamiprid, clothianidin, imidacloprid, thiacloprid, thiamethoxam) in fruit vegetables and estimated the exposure of neonicotinoid pesticide residue through fruit vegetable consumption using a deterministic approach. Two hundred forty samples of eight fruit vegetables cultivated in Korea were analyzed for their pesticide residue contents. Acetamiprid had the highest detection frequency and the highest residue level in pepper. However, all pesticide levels detected didn't exceed national MRLs. The results using a deterministic approach showed that for chronic and acute study of all neonicotinoid pesticide residues, the exposure was about 50 times lower than toxicological endpoint values. It is necessary to understand that the exposure assessment in this study using a probabilistic approach should be regarded as a important knowledge in the decision-making process.

The 88 kinds of pesticide residues were analyzed in 12 kinds(289 samples) of fruits and vegetables brought at department store & mart in Kwangju from Feburary to September in 1999. The detection rate of pesticide residue in 12 kinds(289 samples) of fruits and vegetables was 21.1%, and the rate exceeds standard was 5.2%. The order of highly exceed rate in fruits and vegetables were perilla leaf, lettuce, spinach and chickery. The order of pesticide which founded frequently in fruits and vegetables were procymidone, endosulfan, vinclozoline, chlorpyrifos, cyprermethrin, pirimiphos-M, fenvalerate, fenarimol, and monocrotophos. And that of pesticide which exceed highly standard were procymidone, vinclozolin, endosulfan, pirimiphos-M, fenarimol, monocrotophos, etc. Eight different washing methods were compared for removal efficiencies of residual pesticides(procymidone, vinclozoline) on the perilla leap, the lettuce, the spinach, the strawberry, and the minitomato. Residual pesticides such as procymidone and vinclozoline were removed most efficiently by ultrasonic washing.

We inspected contaminations of pesticides in the 3,313 crop samples grown under the standard of Korean Good Agricultural Practices (GAP) between 2014 to 2016 May. According to our inspection, violations by unregistered pesticide contaminations far outweighed those by exceeding maximum residue limits. Most of the crops contaminated with unregistered pesticides were minor vegetable crops, for which far less pesticide products are registered compared to cereal grains and fruits. And in our second study, the pesticide in the sprayer was removed 90% or more, but not totally by serial rinses. From this result, it is assumed that pesticide remained in the rinsed sprayer can be carried over to crops unintentionally. Our study shows that supplying pesticide products evenly to all kinds of crops and allowing unintentional carry-over of unregistered pesticides to a certain extent are solutions to revitalize depressed Korean Good Agricultural Practices.

The purpose of this study is to monitor the pesticide residues in frozen fruits and vegetables distributed and sold in online and offline markets in Korea. For the study, 107 samples of 34 types of frozen fruits and vegetables were examined, and a total of 341 pesticide residues were analyzed by using multiclass pesticide multi-residue methods of the Korean Food Code. As a result, pesticide residues were detected from 16 of 64 frozen fruits samples and 15 of 43 frozen vegetables samples. Conclusively, residues were detected from 31 samples in total, showing a detection rate of 29.0%. Specifically, pyridaben exceeded the Maximum Residue Limits (MRLs) based on the Positive list system (PLS) in one of the frozen radish leaves, and the violation rate was 0.9%. Detection on frozen fruits and vegetables was made 23 times for 11 types and 36 times for 21 types. In total, 28 types of pesticide residues were detected 59 times. Fungicides were detected the most in frozen fruits, while insecticides were detected the most in frozen vegetables. The most detected pesticides were the insecticide, acaricide chlorfenapyr (5) and the fungicide boscalid (5). Chlorfenapyr was detected only in frozen vegetables, and boscalid was detected in frozen fruits except one.

To perform an effective screening for toxic materials of forensic interest detected in high profile criminal case in biological and environmental samples, we tried to construct a searchable computerized database using HPTLC(High Performance Thin Layer Chromatography) and GC/MS. Retardation factor($R_f$) values and UV spectral data of HPTLC were investigated for 160 pesticides, 34 chemicals and 39 explosives of standard grade. The data were compiled in a library. We also analyzed 112 pesticides, 31 chemicals and 17 explosives and 57 volatile organic compounds(VOCs) by GC/MS. The data for RT and characteristic mass ions were also compiled in a library.
