欧洲化学署ECHA于2020年1月16日宣布将四种化学品纳入第22批高度关注物质候选名单（The candidate list of substances of very high concern，SVHC）。
截至目前，SVHC共计有205项。本次新增的物质如下表所示：
可以看到前三项物质因具有生殖毒性而被列入高度关注物质候选名单，而全氟丁基磺酸及其盐类入选的原因是：可能对人类健康和环境造成严重影响，因此给予与有致癌性、诱变性和再氧化性(CMR)、持久性、生物累积性和毒性(PBT)以及非常持久性和非常生物累积性(vPvB)物质同等水平的关注。
公告称，将全氟丁烷磺酸(PFBS)及其盐列入高度关注物质候选名单的决定是在成员国委员会(MSC)的参特气网与下作出的。
候选名单是可能对人类健康或环境产生严重影响的物质名单，候选名单上的物质也被认为是引起高度关注的物质。一旦它们被列入授权名单，企业将需要申请许可才能继续使用该物质。
任何含有候选物质浓度超过0.1%(按重量计)的物品（的供应商都有对供应链下游的客户和消费者的沟通义务。此外，含有候选物质物品的进口商和生产商从其被列入候选名单之日(2020年1月16日)起有6个月的时间向欧洲化学品管理局通报。
英文原文：
ECHA has added three new substances to the Candidate List due to their toxicity to reproduction and a fourth due to a combination of other properties of concern. This latter causes probable serious effects to human health and the environment, giving rise to an equivalent level of concern to carcinogenic, mutagenic and reprotoxic (CMR), persistent, bioaccumulative and toxic (PBT) and very persistent and very bioaccumulative (vPvB) substances.
The decision to include perfluorobutane sulfonic acid (PFBS) and its salts, was taken with the involvement of the Member State Committee (MSC).
Substances included in the Candidate List for authorisation on 16 January 2020 and their SVHC properties:
Background
The Candidate List is a list of substances that may have serious effects on human health or the environment. Substances on the Candidate List are also known as substances of very high concern and are candidates for eventual inclusion in the Authorisation List. once they are on the Authorisation List, industry will need to apply for permission to continue using the substance after the sunset date.
Companies may have legal obligations resulting from the inclusion of the substance in the Candidate List. These obligations may apply to the listed substance on its own, in mixtures or in articles. In particular, any supplier of articles containing a Candidate List substance above a concentration of 0.1 % (weight by weight) has communication obligations towards customers down the supply chain and to consumers. In addition, importers and producers of articles containing the substance have six months from the date of its inclusion in the Candidate List (16 January 2020) to notify ECHA. Information on these obligations and related tools are available on ECHA’s website.
