因為化學合成技術的進步及工業與生活上的需求，人類製造了大量且種類繁多的有機化學物質，最後都會進入自然環境中。這些有機化學物質對人體及生態環境是否具有危害性，取決於其物理化學特性、其在空氣、水、土壤、底泥、生物體中之濃度及其流佈之行為。本課程之目標即在介紹環境中具有危害性之有機化學物質之特性、影響化學物質行為之機制，訓練學生能建立量化模式以預測有機化學物質之行為及在環境中之宿命。Large amount and various artificial organic chemicals have been released into the natural environment. The hazards which these chemicals will bring to humans depend on their physical and chemical properties, and concentration and hehavior in environmental media. The purposes of this course include the introduction of the basic thermodynamic rules that explain the special properties of organic chemicals, the methods to predict the physical and chemical properties of organic chemicals, and thier effects on the fate of these chemicals in the envrionment.
