計畫中文摘要	地表下土壤及地下水若受揮發性污染物的影響，需要考慮其逸散的風險，環保署「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」中，於第一與二層次的風險評估所推薦的簡易公式必需輸入適當的參數值，以有效的評估地表空氣相受此逸散物的影響，於第二與三層次的風險評估則推薦一些解析模式。本研究主要為評析這些計算逸散風險的簡易模式與評估Jury-finite source、BIOSCREEN解析模式及MOFAT數值模式的使用、建議相關參數的設定方式及測試其敏感性，本研究並收集現場相關資料，實際應用於這些公式與模式，以分析各別方法的使用性。
計畫英文摘要	Contaminant vapors emanating from NAPL, sorbed and dissolved phases pose a human health and environmental risk; it should be assessed by a rigorous way. Environmental Protection Agency in Taiwan provided a guideline on risk assessment and methodology for contaminated subsurface and groundwater. Exposure amount of these vapors from a variety of pathways, as suggested in the guideline for the first and second tiers of risk assessment, are estimated by empirical or theoretical methods with incorporated with some relevant parameters. Some analytical and numerical models were also suggested for the second and third tiers of risk assessment. This study aims at assessing these methods and models, specifically, Jury-finite source, BIOSCREEN and MOFAT models, for their theoretical background and usage. The relevant parameters were also analyzed for sensitivity. Some sets of field data were collected for the use of relevant methods and/or models to assess and compare their results.
