碩士 === 淡江大學 === 水資源及環境工程學系 === 86 === The objective of this research is to develop an integrated system for pollutant fate and risk assessment. The pollutant fate model is a modified version of the Fugacity and MMTD models. Environmental variables used in this system include the geometrical data, pollutant attributes, and risk analysis data. These variables are stored in a database to facilitate retrieval and update. In the integrated system, we use Fugacity model to simulate the pollutant concentration distribution in each compartment. With thThe effect of Dioxins/Furans on the Taipei area is used as a case study to demonstrate the developed integrated modeling system. This study conclude the following result:1. The half-life of Dioxins/Furans in the environment is very long. It requires approximate 100 years to reach steady state. In the end most of the Dioxins/Furans（97%）will reside in soil compartment.2. The food chain is the main human intake pathway for Dioxins/Furans（94%）. Where 6% is from inhalation of contaminated air.3. Meat and Fish are the primary routes of the Dioxins/Furans for the ingestion pathways.4. Currently, we predict a human intake level is 0.05 pg/kg/day in his lifetime, Dioxins/Furans causes cancer at the rate of six per million.5. At the year 2001, with the addition of three municipal waste incinerator being to operate, Dioxins/Furans are projected to causes cancer at the rate of seven per million for male and the rate of six per million for female.
