欧洲化学品管理局（ECHA）近日发布了提案，以确认20个化学物质为高关注物质（SVHC），并将其作为可能的候选授权物质。从半年最后一次的发表来看，卷宗的数量已增加了一倍多。ECHA网站提供了详细的提案建议，有兴趣者可在2011年10月31日前对提案发表评论。           一些成员国和ECHA（应欧盟委员会的要求）已推进了提案以确认这20个化学物质为高关注物质（SVHC）。未来的45日内任何人都可就这些建议发表评论。附表中提供了物质的名称，它们作为SVHC物质的理由及其用途。           评论应主要集中在限定这些物质为SVHC的危险特性及其物质身份鉴别。此外，有兴趣者可就物质的用途，暴露和更安全的替代物质或技术的可取性提供评论和更多信息。需注意的是，这些方面将主要在下一阶段过程中予以考虑（即授权物质的选择），届时将进行新一轮的公共咨询。           当寻求确认这些提议物质为SVHC的一致意见时，及在ECHA将已同意物质列入候选清单前，成员国委员会将回顾这些评论。候选清单中的物质或被选为授权物质。           19个物质被提议，原因是它们对人体健康存在潜在的严重影响。它们被分类为致癌和/或具生殖毒性物质。此外，一个物质由于其具有内分泌干扰特性及对环境存在潜在严重影响，根据REACH法规第57条（f）规定，被提议作为同等关注物质。 对于这其中的两个物质，硅酸铝耐火陶瓷纤维和氧化锆硅酸铝耐火陶瓷纤维，其作为SVHC的提案已于之前提交，并且在2010年1月已被列入候选清单中。然而，有一个情况是，支持将这些纤维物质确定为SVHC的附件XV卷宗的物质定义，其范围太过狭窄，从而不能覆盖欧洲市场上所有组合类型的耐火陶瓷纤维。因此，这些纤维物质新的SVHC提案提供了一个更广泛的物质定义，旨在涵盖所有在欧盟使用的耐火陶瓷纤维类型。           目前候选清单上的物质已有53个。列入该清单后，这对配制品和物品中含有这些物质的供应商提出了新的信息需求。   根据提交的物质附件XV卷宗提供的信息，被提议为SVHC的物质，其提案的理由和潜在用途   物质名称 EC号 CAS号 SVHC特性 潜在用途 Dichromium tris(chromate) 246-356-2 24613-89-6 Art. 57 (a), carcinogenic Mainly used in mixtures for metal surface treatment in the aeronautic/aerospace, steel and aluminium coating sectors.

Zirconia Aluminosilicate Refractory Ceramic Fibres (Zr-RCF) - - Art. 57 (a), carcinogenic Refractory ceramic fibres are used for high-temperature insulation, almost exclusively in industrial applications (insulation of industrial furnaces and equipment, equipment for the automotive and aircraft/aerospace industry) and in fire protection (buildings and industrial process equipment). Formaldehyde, oligomeric reaction products with aniline (technical MDA) 500-036-1 25214-70-4 Art. 57 (a), carcinogenic Mainly used for manufacture of other substances. Minor uses are as hardener for epoxy resins, e.g. for the production of rolls, pipes and moulds, and as well for adhesives. Bis(2-methoxyethyl) phthalate 204-212-6 117-82-8 Art. 57 (c), toxic for reproduction No registration for this phthalate compound has been submitted to ECHA. Hence, the substance seems not to be manufactured in or imported to the EU in quantities above 1 t/y. Main uses in the past were as plasticiser in polymeric materials and paints, lacquers and varnishes, including printing inks. 2-Methoxyaniline; o-Anisidine 201-963-1 90-04-0 Art. 57 (a), carcinogenic Mainly used in the manufacture of dyes for tattooing and coloration of paper, polymers and aluminium foil. 4-(1,1,3,3-tetramethylbutyl)phenol, (4-tert-Octylphenol) 205-426-2 140-66-9 Art. 57 (f), equivalent level of concern Mainly used in the manufacture of polymer preparations and of ethoxylates. Further used as a component in adhesives, coatings, inks and rubber articles. 1,2-Dichloroethane 203-458-1 107-06-2 Art. 57 (a), carcinogenic Mainly used for manufacture of other substances.
