A substance of very high concern (SVHC) is a chemical substance (or part of a group of chemical substances) for which it has been proposed that the use within the European Union be subject to authorisation under the REACH Regulation.〔(Regulation (EC) No 1907/2006 of the European Parliament and of the Council of 18 December 2006 concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), establishing a European Chemicals Agency. ) ''OJEC'' L396, 30.12.2006, pp. 1–849.〕 Indeed, listing of a substance as an SVHC by the European Chemicals Agency (ECHA) is the first step in the procedure for restriction of use of a chemical. The first list of SVHCs was published on 28 October 2008 and the list update many times to include new candidates till the last update on 15 June 2015 to include a total 163 SVHC.〔(Candidate List of Substances of Very High Concern for authorisation )〕 == Criteria == The criteria are given in article 57 of the REACH Regulation.〔Article 57, REACH Regulation, at pp. 141–42.〕 〔http://ec.europa.eu/environment/chemicals/reach/legislation_en.htm〕 A substance ''may'' be proposed as an SVHC if it meets one or more of the following criteria: *it is carcinogenic; *it is mutagenic; *it is toxic for reproduction; *it is persistent, bioaccumulative and toxic according to the criteria set out in Annex XIII to the REACH Regulation〔Annex XIII, REACH Regulation, at pp. 383–85.〕 (PBT substances); *there is "scientific evidence of probable serious effects to human health or the environment which give rise to an equivalent level of concern"; such substances are identified on a case-by-case basis. The "equivalent concern" criterion is significant because it is this classification which allows substances which are, for example, neurotoxic, endocrine-disrupting or otherwise present an unanticipated environmental health risk to be regulated under REACH.〔(【引用サイトリンク】title=Proposals to identify Substances of Very High Concern current consultations )〕 Simply because a substance meets one or more of the criteria does not necessarily mean that it will be proposed as an SVHC. Many such substances are already subject to restrictions on their use within the European Union, such as those in Annex XVII of the REACH Regulation.〔Annex XVII, REACH Regulation, at pp. 395–849.〕 SVHCs are substances for which the current restrictions on use (where these exist) might be insufficient. There are three priority groups for assessment:〔Article 58.3, REACH Regulation, at p. 144–45.〕 *PBT substances and vPvB substances; *substances which are widely dispersed during use; *substances which are used in large quantities. 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「Substance of very high concern」の詳細全文を読む スポンサード リンク
