According to REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) legislation, i.e. REGULATION (EC) No 1907/2006 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 18 December 2006, Annex 1 manufacturers and importers of chemical substances are required to calculate DNELs as part of their Chemical Safety Assessment (CSA) for any chemicals used in quantities of 10 tonnes or more per year. The DNEL is to be published in the manufacturer’s Chemical Safety Report (CSR) and, for hazard communication, in an extended Safety Data Sheet. == Links == *(What are DNELs? ) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Derived no-effect level」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
