歐盟於2006年12月公布化學品註冊、評估、授權暨限制規則，建立一個化學品管理的整合體系。該規則以源頭註冊登錄為基礎，要求製造商及進口商自行提供各該化學物質之安全性及風險評估資訊，以逐步建立化學物質資訊系統，並促進危險化學物質之替代，俾達成永續發展的目標。我國在民間環保團體不斷呼籲下，終於在2013年12月修改毒性化學物質管理法，引進REACH制度，並加入毒化物釋放量資訊公開規定，日前更發布新化學物質及既有化學物質資料登錄辦法。本文旨在探討歐盟REACH制度內涵，進而檢討我國新建立的REACH制度之利弊得失。

The EU announced Regulation (EC) No 1907/2006 concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) and thereby established an integrated system for chemicals in December 2006. This regulation requires manufac-turers and importers to assess the risks posed by chemical substances they manufacture or import, and to take the steps necessary to manage known risks. They are obligated to prove the safety of chemical substances. In other words, the EU REACH system is based on registration at the source, requires manufacturers and importers to provide all the safety and risk assessment information on chemical substances, and in this way builds gradually an information system of existing and new chemical substances, promotes substitutions for hazardous chemicals, and serves to achieve the goal of sustainable development. This system has already been adopted by many coun-tries and become a new, international trend in chemicals manage-ment. Under pressure from the ongoing appeals from environmental groups, in December 2013, Taiwan modified finally the “Toxic Chemical Substances Control Act,” introducing not only the REACH system, but also information disclosure concerning the re-lease of toxic chemicals. Recently, the EPA further issued the “Reg-ulation of New and Existing Chemical Substances Registration.” This study aims to explore the contents of the EU REACH system, and then review the advantages and disadvantages of the newly es-tablished REACH System in Taiwan.
