초록

현재 국내 사용중이며 내분비계 장애추정농약으로 분류된 benomyl, carbaryl, endosulfan등 17종 농약에 대한 estrogen성 영향을 검색하기 위하여 인체난소암세포(BG1Luc4E2)를 이용한 luciferase assay를 수행하였으며, luciferase assay에서 Eeq를 산출한 후 내분비계 장애추정 농약의 에스트로겐성 영향에 대한 식이섭취 위험도 평가를 실시하였다. Estrogen 수용체 결합시험에서 cypermethrin, dicofol, endosulfan, esfenvalerate 및 fenvalerate가 $10^{-5}$ M에서 최고 영향이 관찰되었고, mancozeb 등 8종 농약은 약한 영향이 관찰되었으며, benomyl 등 나머지 4종 농약은 영향이 없었다. 이들 중 활성이 비교적 강한 dicofol 및 endoeulfan의 1 nmol 17 $\beta$-estradiol에 대한 RLP 와 RLU는 dicofol의 경우 $10^{-5}$ 및 56%이었구, endosulfan은 $10^{-5}$ 및 72%이었다. MRL을 이용한 식이섭취 위험도 평가 결과 농약들의 추청 1일 최대농약섭취량은 cypermethrin 0.667, dicofol 0.1462, endosulfan 0.2066 및 lenvalerate/esfenvalerate 0.2098 mg/person으로 총 추정 1일 최대 농약섭취량이 1.2298 mg/person이었고, 남성 혈중 에스트로겐 증가 농도는 3.075 ng/L로 정상농도에 비해 15%정도 증가하였으나, 국내 모니터링 성적을 기준으로 평가한 결과 남성혈중 에스트로겐 증가 농도는 0.01938 ng/L로 정상농도에 비해 0.09693%정도 증가하였다.

The present study was conducted to test and evaluate estrogenic effect of 17 pesticides including benomy1 and carbaryl, being suspected as endocrine disrupting chemicals. For estrogenic effect examination, luciferase assay were achieved with human ovarian cancer cell, BG1Luc4E2. Estrogenic effects of cypermethrin, dicofol, endosulfan, esfenvalerate, and fenvalerate were observed at the concentration of $10^{-5}$ M by estrogen receptor binding assay. Relative luciferase potency and relative luciferase effects compared with $10^{-10}$ M 17 $\beta$-estradiol were $10^{-5}$, 56% for dicofol, and $10^{-5}$, 72% for endosulfan, respectively. Estimated maximum daily intake for pesticides was calculated from maximum residue limit of agricultural commodity and food consumption was 1.2298 mg/person. Theoretically calculated blood estrogen level from dietary intake for pesticides based on MRL in Korea, 3.075 ng/L was equivalent to 15% of estrogen concentration in normal blood, but practical monitoring data, 0.01938 ng/L was equal to 0.09693% of estrogen concentration in normal blood.
