계절별(繫節別)로 안동지방(安東地方)에서 생산(生産)되는 김치재료(材料) 채소의 농약오염도(農藥汚染度)를 보기 위하여 배추, 무우. 마늘, 고추, 오이등(等)을 수집하여 유기염소계(有機鹽素系)와 유기린계(有機燐系) 농약(農藥)을 분석(分析)해 본 결과(結果)는 다음과 같았다. 1) 초여름김치 재료(材料)채소에는 유기염소계(有機鹽素系) 농약오염(農藥汚染)이 많은 편이었고 때로는 잔류허용량(殘留許容陽)을 넘는 경우가 있었으며 토양살충제(土壤殺蟲劑)인 Heptachlor의 오염빈도(汚染頻度)는 가장 높았다. 2) 유기린계농약(有機燐系農藥)은 유기염소계농약(有機鹽素系農藥)에 비(比)하여 검출(檢出)되는 빈도(頻度)도 낮고 잔류허용량(殘留許容陽)에도 미치는 일이 없었다. 3) 늦여름 채소에 오염(汚染)된 유기염소농약(有機鹽素農藥)은 초여름 보다 높은 농도(濃度)로 검출(檢出)되는 경우가 많았고 반면에 유기린계농약(有機燐系農藥)의 검출(檢出)은 훨씬 그 빈도(頻度)가 낮았다. 4) 늦가을 김장용 채소의 오염농약농도(汚染農藥濃度)는 매우 낮았으며 검출빈도(檢出頻度)도 낮았다. 5) 늦가을 김장채소에는 잔류성(殘留性)이 약한 유기린계농약(有機燐系農藥)의 오염(汚染)은 거의 볼 수 없었다. 6) 이상(以上)의 결과(結果)로 농약사용량(農藥使用量)이 많은 여름철 채소를 많이 섭취하는 것은 그 잔류성(殘留性)으로 보아 위생적(衛生的)으로 불안(不安)한 일이라 하겠다.

The objective of this study was to evaluate the effectiveness of using HR-GC/MS for the rapid screening of dieldrin residues in soils. Persistent organic pollutants (POPs) of organochlorine pesticides such as dieldrin, were analyzed in sedimentary rock and granite rock collected from greenhouses, Niigata, Japan. Dieldrin remains in Japanese farming soils, more than 40 years after their use as insecticides was prohibited. The averages in soil moisture ranged from 2.79% to 7.20% in soils derived from sedimentary rock and from 25.59% to 31.40% in soils derived from granite rock. Mean concentrations of dieldrin residues in sedimentary rock and granite rock were $39.7ng\;g^{-1}$ and $40.51ng\;g^{-1}$, respectively. Dieldrin residue was detected at a slightly higher concentration in granite rock than sedimentary rock samples. There was no consistency between the two soils or between surface and subsurface soils. The coefficients of variation of the two soils were 10.6% and 8.7%, respectively. These results suggest that our high-resolution mass spectrometry detector (HR-GC/MS) is effective at analyzing residual organochlorine pesticides in soil. In order to increase the precision and sensitivity for chemical analysis of POPs, high-resolution gas chromatography coupled with a HR-GC/MS is highly recommended.

Gaseous organochlorine pesticides (OCPs : heptachlor epoxide, p, p'-DDE, ${\gamma}-HCH,\;{\alpha}-chlordane,\;{\gamma}-chlordane$ and trans-nonachlor) concentration was measured using PUF high volume sampler from June, 2000 to June, 2002 in the semi-rural atmosphere. The OCPs concentration in atmosphere, which is estimated by the slope (m) of Clausius-Clapeyron equation and phase-transition energy $({\Delta}H)$, was influenced by revolatilization from environmental matrix (soil, water and tree leaves) and a long range transportation of air mass. But the former affected OCPs concentration more than the latter. The degradation rate constants (k) of OCPs calculated using multiple regression analysis and revised standard temperature method were in good agreement each other. The value of k of ${\gamma}-HCH$ was very low as -0.0007, but the range of k of other components were $-0.00l8{\sim}-0.0038$. The half-life $({\tau})$ which was calculated by k of ${\gamma}-HCH$ was 2.6 years-the longest one, but that of heptachlor epoxide was in 0.5 year-the shortest one. $({\tau})\;of\;{\alpha}-chlordane,\;{\gamma}-chlordane$ and trans-nonachlor in technical chlordane was 1.0, 1.1 and 0.7 year respectively.

A multiresidue method(MRM) for pesticides must be rapid and must test a wide variety of pesticides at relevant toxicological concentrations. In this study, three kinds of major analytical methods such as Korean Food Code Method, CDFA MRM, and Holstege's method are tested to compare the average recoveries, solvent consumption, and required time for the analysis of 18 organochlorines, 18 organophosphates, and 6 carbamates in spinach samples. Samples for pesticides analysis were extracted and cleaned up according to the respective methods and detected by gas chromatography with selective detectors, ECD and NPD, HPLC with postcolumn reaction system(PCRS). Average recovery of 42 pesticides by Korean Food Code method, CDFA method, and Holstege's method were 91.3%, 88.1%, 89.0%, respectively. Amount of solvent consumption and required time for the analysis of Korean Food Code method were from two and a half times to three times as much as those of another two methods. For the development and legal application of more rapid and effective MRMs, prolonged study is necessary.

Objectives: This study was performed to investigate if organochlorine pesticides (OCPs) were associated with metabolic syndrome and insulin resistance among non-diabetes. Methods: Among subjects who participated in a community-based health survey, 50 non-diabetic subjects with metabolic syndrome and 50 normal controls were selected. Insulin resistance was measured by the homeostasis model assessment (HOMA-IR). Eight OCPs were selected. Results: After adjusting for confounders except for body mass index (BMI), beta-hexachlorocyclohexane ($\beta$-HCH) and heptachlor epoxide were positively associated with metabolic syndrome. Odds ratios across tertiles of $\beta$-HCH and heptachlor epoxide were 1.0, 3.2 and 4.4, and 1.0, 4.0 and 6.0, respectively (p for trend = 0.01 and <0.01). After additional adjustment for body mass index (BMI), heptachlor epoxide still showed an increasing trend with adjusted odds ratios of 1.0, 4.1, and 4.6 (p for trend = 0.10). When the five components of metabolic syndrome (with the definition of high fasting glucose ($\geq$ 100 mg/dL) were separately analyzed, all components were positively, but not significantly, associated with heptachlor epoxide. As the serum concentration of heptachlor epoxide increased, HOMA-IR increased significantly in subjects with metabolic syndrome even after adjusting for BMI (p value <0.05 and <0.01). Conclusions: Despite the small sample size, this study suggests that the background exposure to some OCPs may be associated with metabolic syndrome.

Bivalve samples from 30 locations Korean coastal waters were analyzed to characterize the contamination with and distribution of polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs). The congeners of PBDE in 30 bivalve samples were analyzed by high resolution gas chromatography with a high resolution mass detector. The levels of PBDEs in bivalve samples ranged from 0.092 to 13.5 ng/g wet weight. These values for PBDEs concentrations in bivalves from Korea were higher than or comparable to available values for bivalves from other countries. In the congener profiles, BDE-47 (mean contribution=42.2%) was predominant, followed by BDE-99 (23.1%), BDE-100 (11.9%) and BDE-154 (3.5%). Among the OCs analyzed, $\Sigma$PCBs and $\Sigma$DDTs levels were highest, followed by $\Sigma$HCHs, $\Sigma$CHLs and HCB. The wet weight based $\Sigma$PCBs and $\Sigma$DDTs ranged from 0.28 ng/g to 19.4 ng/g, and from 0.19 ng/g to 4.86 ng/g, respectively. The $\Sigma$PCBs and $\Sigma$DDT slevels in bivalves along the entire Korean coast were lower than those of the USA, and below the Food and Drug Administration (USA. FDA) limits for fish and shell fish. However, the human health criteria and wild life criteria of the USA. Environmental Protection Agency (USA. EPA) were exceeded for DDE and $\Sigma$HCHs at most of the sampling points.

경기도 안성시 한경대학교에서 1999년 7월부터 11월까지 2주간격으로 대기중 OCPs를 측정하였다. 현재도 사용중인 것으로 보고된 endosulfan I과 II의 농도가 오래 전에 사용 금지된 다른 OCPs와 대사물질의 농도보다 훨씬 높았다. 그리고 모화합물인 heptachlor보다는 대사물질인 heptachlor epoxide가 더 높은 농도를 보였다. 이것은 이 성분이 사용된 지 상당히 되었지만, 환경중에서 독성이 강한 대사물질로 전환되어 잔류함을 알 수 있었다. 그리고 모든 OCPs는 가을보다 여름에 높은 농도를 보였다. 온도가 높은 여름에 air-surface exchange과 관련된 휘발작용으로 농도가 높아지고 온도가 낮은 가을에 농도가 감소함을 알 수 있었다. 그렇지만 endosulfan I과 II는 온도의 영향뿐만 아니라 사용량과 관련성이 있는 것으로 사료되었다.
