Abstract

Tributyltin compounds have been increasingly used in the form of plastic stabilizers, catalytic agents, industrial agricultural biocides, antifouling paint, and pesticides. Among these organotin compounds, large amounts of tributyltin(TBT) and triphenyltin(TPT) have been used as antifouling agents because they have a superior ability to prevent marine organism from being encrusted on ship bottoms and in culturing nets. Environmental pollution by these organotin compounds in the aquatic environment were undertaken. The international maritime Organization's established a provisional tolerable daily intake(TDI) of 1.6[micro]g TBTO/kg/ B.W. The Food and Agiculture Organization (of the United Nations)/world Health Organization's (FAO/WHO) proposed a TDI of 0.5ug TPT/kg BW/d. This study is conducted monitoring of TBT on seafoods in Korea and risk assessment for exposure on TBT in seafoods. Total hazard index(using Reference Dose : 0.3 ug TBTO/kg B.W/day) of intake exposure on seafoods is 0.04 as the 50th percentile, 0.08 as the 95th percentile. This value is estimated by Monte-Carlo simulation using Crystal Ball(Decisioneering Co., 2001).

국내 6개 주요도시에서 조사된 어패류 오염도 현황을 토대로 우리나라 사람들의 어패류 섭취를 통한 유기주석화합물 인체노출량을 예측하고, 이에 따른 위해도를 추계하였다. 본 연구결과를 살펴보면 갈치의 경우, 성인이 식품수급표에서 제시하는 일일섭취량 3.02g/day를 평생 섭취한다는 노출시나리오하에 평균일일노출량은 확률분포로 나타냈을 때 그 중간값이 6.48$\times$ $10^{-7}$ mg/kg/day, 상한치 95th percentile값이 8.78$\times$$10^{-7}$ mg/kg/day로 나타났음을 알 수 있다. 본 연구에서는 비발암독성영향을 평가하기 위하여 BMD$_{10}$ 을 활용한 참고치(Reference dose)를 예측하였다. 이 때 BMD$_{10}$은 10% 비교변화를 BMR으로 하였을때 해당하는 용량의 95% 하한치이다. 본 연구에서 활용한 BMD는 digestion에 의한 근육내의 IgE titer, T.spiraris larvae와 조직학에 의한 근육내 T.spiraris larvae에 근거하여 예측된 것으로 0.03 mg/kg/day이다. 참고치는 BMD$_{10}$ 0.03 mg/kg/day에 불확실성 계수 100을 고려한 값으로 0.003 mg/kg/day이며, 이 때 활용한 불확실성계수는 실험동물에서 인체로의 외삽과정에서 고려한 계수 10과 인구집단 내 민감그룹 고려를 위한 계수 10을 적용한 것이다. 각 어패류의 위험지수(50th percentile)를 살펴보면 고등어에서 2.04$\times$ $10^{-2}$으로 가장 높게 나타났으며, 소라에서 2.70$\times$ $10^{-5}$으로 가장 낮은 값을 나타냈다.
