這一新的限制要求企業(yè)不再將文本所涵蓋的PFCA作為一種物質(zhì)、混合物和物品在市場(chǎng)上銷(xiāo)售，如果其質(zhì)量濃度超過(guò):

?C9-C14 PFCAs及其鹽類(lèi)的總和：25 ppb (0.025 mg/kg);

?C9-C14 PFCAs相關(guān)物的總和：260 ppb (0.260 mg/kg)。

此限制所涵蓋的物質(zhì)列在ECHA網(wǎng)站的問(wèn)答(Q&A)頁(yè)面上:

-PFNA (C9-PFCA, CAS No. 375-95-1)及其鹽

-PFDA (C10-PFCA, CAS No. 335-76-2)及其鹽

-PFUnDA (C11-PFCA, CAS No. 2058-94-8)及其鹽

-PFDoDA (C12-PFCA, CAS No. 307-55-1)及其鹽

-PFTrDA (C13-PFCA, CAS No 72629-94-8)及其鹽

-PFTDA (C14-PFCA, CAS No. 376-06-7)及其鹽;

以及根據其結構公式有可能降解或轉化為C9-C14全氟羧酸的任何其他與PFCA有關(guān)的物質(zhì)。

草案規定，從2023年7月4日起，對個(gè)人防護服(PPE)的“防水或防油紡織品”進(jìn)行臨時(shí)豁免。

PFCAs是PFAS(全氟烷基物質(zhì)和多氟烷基物質(zhì))的一個(gè)子集，根據ECHA上個(gè)月公布的另一項限制草案，成員國也希望在歐洲完全限制其制造和使用。

This new restriction requires companies to no longer place on the market PFCAs covered by the text as a substance, in mixtures as well as in articles if their mass concentration exceeds:

·25 ppb (0.025 mg/kg) total of C9-C14 PFCAs and their salts;

·260 ppb (0.260 mg/kg) in sum of C9-C14 PFCA-related substances.

The substances covered by this restriction are listed on the Questions & Answers (Q&A) page of the ECHA website:

-PFNA (C9-PFCA, CAS No. 375-95-1) and its salts,

-PFDA (C10-PFCA, CAS No. 335-76-2) and its salts,

-PFUnDA (C11-PFCA, CAS No. 2058-94-8) and its salts,

-PFDoDA (C12-PFCA, CAS No. 307-55-1) and its salts,

-PFTrDA (C13-PFCA, CAS No 72629-94-8) and its salts,

-PFTDA (C14-PFCA, CAS No. 376-06-7) and its salts;

As well as any other PFCA-related substances which, according to their structural formulas, have the potential to degrade or transform into C9-C14 perfluorocarboxylic acids.

The text provides for some temporary exemptions for "water-repellent or oil-repellent textiles" for personal protective clothing (PPE), which will only be affected by this restriction from July 4, 2023.

PFCAs are a subset of PFAS (per- and polyfluoroalkyl substances) which Member States also want to completely restrict the manufacture and uses of in Europe under another draft restriction published by ECHA last month.
