之前包含在限制条目 68 中的 PFOA 物质怎么样了？该条目目前涵盖哪些物质？

What happened to PFOA substances previously included into restriction entry 68 and what substances are currently covered by this entry?

限制条目 68 于 2017 年 6 月 14 日首次由委员会条例 (EU) 2017/1000 纳入 REACH 附件 XVII，最初涵盖全氟辛酸 (PFOA)、其盐类和 PFOA 相关物质。2020 年 6 月，PFOA 物质被进一步纳入持久性有机污染物条例（条例 (EU) 2019/1021）限制物质清单，因此从 REACH 附件 XVII 中删除。随后，2021 年 8 月 4 日委员会条例 (EU) 2021/1297 纳入了 REACH 附件 XVII 的新条目 68（条目编号相同，但包含新物质），该条目限制了碳链中含有 9 至 14 个碳原子的全氟羧酸（C9-C14 PFCA）、其盐类和 C9-C14 PFCA 相关物质的上市和使用。

Restriction entry 68 was first included into Annex XVII to REACH by Commission Regulation (EU) 2017/1000 on 14 June 2017 and it initially covered Perfluorooctanoic acid (PFOA), its salts and PFOA-related substances. PFOA substances have been further included in the list of substances restricted under the POPs Regulation (Regulation (EU) 2019/1021) in June 2020 and consequently removed from Annex XVII of REACH. A new entry 68 of Annex XVII to REACH (same entry number but new substances) was subsequently included by Commission Regulation (EU) 2021/1297 of 4 August 2021, as corrected, which restricts the placing on the market and use of perfluorocarboxylic acids containing 9 to 14 carbon atoms in the chain (C9-C14 PFCAs), their salts and C9-C14 PFCA-related substances.
