求助--大家帮忙解答下关于(PFOS)的
欧盟《关于限制全氟辛烷璜酸销售及使用的指令》（即PFOS指令）将于2008年6月27日正式实施。指令规定，以PFOS（全氟辛烷璜酸）为构成物质或要素的，若浓度或质量等于或超过0.005%的将不得销售；而在成品和半成品中使用PFOS浓度或质量等于或超过0.1%的，则成品、半成品及零件也将被列入禁售范围。
有文章说金属镀层的PFOS排放也应逐步做消减，我想问下在PCB印刷线路板行业的电镀制程有可能出现PFOS么？

In some ways this is a trick question, as the current thinking is that consumer products don't contain PFOA. This is because PFOA is used in the manufacturing of some products, but is not supposed to remain.
This said, many of these same products also contain chemicals called telemers which may degrade over time and form PFOA in environment. Some industrial fluoropolymer dispersion products contain PFOA, but are commonly used in heat treated applications that would remove the PFOA from final products prior to their leaving the manufacturing plants.
The only company that manufactures PFOA in the United States is the DuPont company, though 3M also manufactured the acid up until the year 2002. Worldwide, comapanies that manufacture telemers include DuPont, Clariant GmbH, Daikin Industries and Asahi Glass.
以上供参考.
