유기염소제(有機鹽素劑)-PCBs 혼합(混合) 환경시료(環境試料)의 잔류분(殘留分) 분석(分析)을 목적(目的)으로 PCBs의 오염(汚染) 가능성(可能性)이 짙은 공단주위(工團周圍) 수원(水原), 이리(裡里) 및 칠곡(漆谷) 지역(地域)의 하천(河川)과 전답(田沓) 토양(土壤)을 분석(分析)하여 다음과 같은 결과(結果)를 얻었다. 공시(供試) 토양시료(土壤試料)는 모두 유기염소제(有機鹽素劑)에 의(依)하여 오염(汚染)되어 있었으나, PCBs는 1개(個) 시료(試料)에서도 검출(檢出)되지 않았다. 8가지 유기염소제(有機鹽素劑) 농약잔류분(農藥殘留分)에 대한 오염율(汚染率)은 수원토양(水原土壤), 이리토양(裡里土壤), 칠곡토양(漆谷土壤) 순(順)으로 감소(減少)하였다. BHC 이성질체(異性質體)와 DDT는 모든 시료(試料)에서 발견(發見)되았다. DDT의 잔류수준(殘留水準)은 $0.006{\sim}0.840\;ppm$으로 가장 높았는데, 미지(未知)의 화합물(化合物)이 기여(寄與)했을 가능성(可能性)을 전적(全的)으로 배제(配除)할 수는 없다.

Solid phase micro-extraction (SPME), a solvent-free, rapid and inexpensive method for the extraction of organic compounds from aqueous sample matrices, was evaluated for determination of the 120 pesticides in vegetables such as crown daisy, perilla leaf, leafy lettuce and to mato. The analysis conditions were chosen for the SPME method: 15 min of immersion of the PDMS fiber in 10 ml of the solution with stirring at 1,000 rpm. The recovery tests were carried out in triplicate. The range of recoveries was 0-142% for organochlorine pesticides and $4.9\sim200\%$ for organophosphorus pesticides. The recoveries were very low in the pesticide groups with low solubility in water. The recoveries became lower in proportion to the interference materials in vegetables. The recovery in tomato was relatively higher than that in perilla Ie af and crown daisy. The recovery values obtained by SPE and SPME were compared. In leaf y lettuce, recovery obtained by SPE method ranged from $58.1\%\;to\;136.1\%$ and recovery by SPME ranged from $9.6\%\;to\;176.3\%$ In organophosphorus pesticides. The recovery in SPME method was satisfactory with $136\%$ for ethoprophos, $119\%$ for methidathion and $113\%$ for diazinon. Meanwhile, recovery of EPN, phenthoate and 2,4-DDT revealed relatively low value of $38\%,\;41\%\;and\;3.4\%,$ respectively. However, most of pesticides applied to SPME method sho wed constant recovery and precision. From these results, it can be concluded that solid phase micro-extraction might be an appropriate method for the screening test of pesticides in vegetables.

최근 많은 종류의 농약들이 개발되었으며, 경작지역(agricultural area) 뿐만 아니라 골프장, 공원 및 정원에 널리 사용해 왔다. 이들 농약들은 인체 및 동물들에 유해한 영향을 미치는 것으로 알려져 있으며, 더욱이 농약이 살포된 지역주변의 수질 및 대기의 오염은 사회적 문제로 부각되고 있다. 따라서 환경중 농약들의 농도를 측정하여 그들의 거동을 연구하는 것은 매우 중요하다(Haraguchi et al.,1994). (중략)

Attention-deficit hyperactivity disorder (ADHD) is a common, childhood-onset, neuropsychiatric disorder with an estimated prevalence of 2-7.6% in Korean children. Although the etiology of ADHD is not well understood, evidence from genetic factor and environmental factor studies suggests that ADHD results from a gene environmental interaction. In the current study, we reviewed the evidence for and clinical implications of the hypothetical roles of organophosphate pesticides, organochlorine pesticides, polychlorinated biphenyls, phthalate, bisphenol, polyfluoroalkyl chemicals, polycyclic aromatic hydrocarbons, mercury, lead, arsenic, cadmium, manganese, tobacco, alcohol as harmful risk factors in the development of ADHD.

Chlorobenzenes (CBs) are ubiquitous hydrophobic chlorinated organic compounds in the environment. These compounds are used as de-ordants, solvents and pesticides, as well as byproducts of agro- or petro-chemical related manufacturing processes, such as PCBs and pentachlorophenol, or of biodegradation of lindane (Newhook and Meek, 1994). Unlike some organochlorine (OC) compounds, including polychlorinated biphenyls (PCBs) and various pesticides, CBs are not banned from production or use in any country. (omitted)

유기인제, 유기염소제, 카바메이트제 및 피레쓰로이드제 농약을 한 번의 전처리와 주입으로 동시에 정량 및 정성분석할수 있는 실험법을 연구하였다. 자동 soxhlet 추출 장치로 쌀시료로 부터 농약을 추출해내고, 이 추출물의 용매를 증발시킨후 hexane에 재용해하고 Sep-Pak florisil catridge를 이용한 고체상 추출법으로 정제하였다. Soxhlet 추출의 용매는 acetone을 사용하였고, 정제시의 용출용매로는 ethyl acetate-n-hexane (1:1) 혼합 용매를 사용하였다. 이와 같은 전처리 과정을 거친 시료액을 GC에 주입하고, 중간극성의 칼럼에 질량검출기를 통해 검출하였다. 이 분석법으로 쌀시료에 대해 3회의 회수율 실험을 하였을 때 captafol과 captan 등을 제외한 42종 농약이 70% 이상의 회수율을 나타내었고, 3회 반복된 실험치 간의 표준편차는 $0.29{\sim}9.07$의 범위로 나타나 비교적 양호한 재현성을 보였다.

To understand environmental paths of the transport and accumulation of endocrine disrupting chemicals (EDCs), a single cell multimedia fate model has been constructed and evaluated. The EDCs of concern were PAHs, Organochlorine Pesticides (OCPs), PCBs, Alkyl phenols, and phthalates. An evaluation model was designed for the multimedia distribution, including air, water, soil, sediment and vegetation. This model was verified using reported values and via monitoring data. Based on collected data, the distribution trends of EDCs with respect to environmental media were analyzed. Those results have applied to the model for the prediction of the spatial and temporal distribution of EDCs in Seoul. Especially, phenol compound, phthalates, PAHs, PCBs and organochlorine pesticides were estimated and the model was verified. This model was successfully conducted to environmental media, such as air (vapor and suspended particles), soils (forest soil, bare soil, and cement-concrete covered soil), water (dissolved and suspended solids), sediment, trees (deciduous and coniferous). The discrepancies between the model prediction and the measured data are approximately within or near a factor of 10 for the PAHs of three rings through that of six rings, implying that multimedia distribution of the PAHs could be predicted with a factor of 10. Concerning about the air equilibrium may be assumed, a fugacity at steady state is similar in all environmental media. Considering the uncertainties of this model, the use of equilibrium models may be sufficient for assessing chemical fates. In this study, a suggestion was made that modeling and estimation of chemicals in environmental multimedia be rigorously evaluated using the measured flux data. In addition, these data should be obtained, for example, from the precise and standardized inventory of the target chemicals. The model (EDC Seoul) will be refined in an on-going research effort and will be used to support decision-making concerning the management of EDCs.
