摘要
台灣光電產業近年來蓬勃發展,製程中大量使用三氯乙烯使用於洗淨製程,而國內土壤與地下水遭受三氯乙烯污染問題也會陸續發生,其間接導致人類暴露三氯乙烯的致癌風險以其利用風險評估推估疑似污染場址之整治目標。
風險評估是風險管理應用的工具其中一種,預估人類暴露在不同程度的污染物,其健康所造成的風險嚴重程度,本研究是參考「美國超級基金場址風險評估制度」與「行政院環境保護署土壤及地下水污染場址健康風險評估評析方法及撰寫指引」,藉由危害鑑定、劑量反應評估、暴露量評估與風險判定推估和整治目標推估,疑似污染場址作業員工暴露三氯乙烯的總致癌風險與依據實測資料進行實地風險評估作為污染整治目標訂定。
根據計算結果,總致癌暴露量風險為 1.48 總致癌風險大於 10-6,疑似污染場址需立即整治與以風險評估推估疑似污染場址土壤與地下水污染三氯乙烯之整治目標分別為 0 mg/kg 與 1.44 * 10-2 mg/L。
關鍵詞:風險評估、危害鑑定、劑量反應評估、暴露量評估、風險判定推估。

Abstract
This research focuses on the assessment of a potential contaminated site, which is suspected to be polluted by trichloroethylene (TCE). Discussing the physical and chemical characteristics of the soil and groundwater is necessary to realize the exposing pathways of TCE in the polluted places. Besides, according to the TCE distribution, it can be used to predict the characteristics of health risks .The development of optoelectronics is very rapidly. Therefore; TCE is used for cleaning process of photoelectron component .The problems of TCE, in Taiwan, of the soil and groundwater are also gradually noticed and observed nowadays; therefore, the healthy issue of exposing to surroundings which is polluted by TCE is highly concerned and debated. It causes people having the risks of cancer by exposing TCE indirectly.
Risk assessment is one of tools for risk administration of photoelectron component. Assess people who assess TCE ratio will expose in different levels of pollutions which lead to various health diseases. The research approaches of response assessment, exposure assessment and risk characterization are based on the benchmark of “Pollution Site Risk Assessment System from Superfund in US EPA” and “Soil and groundwater pollution site health risk assessment and evaluation of Taiwan EPA”, and hazard identification. According to Mays's results, the risk ratio of causing cancer disease under TCE-contaminated site will be 1.48.
As Mays has pointed out that the ratio could be 1.87. Therefore; it can be seen that the ratio is more than 10-6. Environment which is assumed polluted by TCE has to be examined immediately and the surroundings polluted by trichloroethylene should be reached dealing target improved to the statistic of 0 mg/kg and 1.44 * 10-2 mg/L.
