本計畫彙整研析歐盟、美國、加拿大、日本、韓國及中國等六國之化學物質整體管理架構，包含優先關切物質篩選原則、風險評估方法、模式工具、系統資料庫及風險知識平台之發展與建置現況，並依據我國環境風險評估執行經驗、歷年化學物質環境流布濃度調查資料及相關模式本土化參數建置概況等，參酌各國管理策略及化學物質風險評估方式，綜合研提規劃我國化學物質環境風險評估架構、化學物質環境風險資訊整合規劃、風險知識建立應用方式、及化學物質環境流布調查綱要計畫，並透過兩場次專家諮詢會議蒐集專家建議，以做為我國後續發展化學物質環境風險評估作業流程及建置環境風險資訊整合資料庫之基礎。

This project has summarized the comprehensive management structures from 6 different nations including European Union, U.S.A., Canada, Japan, Korea, and China, which include contents like the principles for selecting prior concerned substances, methods for risk assessment, assessment model, systematic data base, and the development of the knowledge platform about environmental risk. Meanwhile, this project has also referenced the local information like executive experience of environmental risk assessment in Taiwan, the data from the historical concentration investigation for the environmental chemical distribution, and the development of building local parameters. From the management strategy and methods for environmental risk assessment of chemical substances from other nations, this project has planned and proposed the assessment and information integration structure for environmental risk from chemical substance, and the general investigation plan for the environmental chemical distribution. Besides the process mentioned above, this project has also collected suggestions from experts by holding expert consultations as a foundation to develop an operation process for the environmental risk assessment of chemical substances and an integrated data base of environmental risk information.
