In the summer of 2019, eleven of the best-selling fluorinated ski wax products were purchased from one of Norway's largest sports stores and soon after analysed for a suite of 26 per- and polyfluoroalkyl substances (PFAS). The waxes were shown to contain a wide range of perfluoroalkyl acids, including perfluoroalkyl carboxylic acids with up to 25 carbons. Of particular concern was the finding that perfluorooctanoic acid (PFOA) levels in nine of the eleven ski lubrication products analysed were above the EU limit values of 25 ng g⁻¹, which came into force on 4^th July 2020. The ski wax with the highest PFOA levels had a concentration that was 1215 times higher than the EU restrictions. Although some of the ski wax manufacturers have indicated that they have switched to formulations that contain chemistries based on shorter perfluoroalkyl chains, the analytical results show that this is not the case.

2019年市场上滑雪蜡产品中的全氟和多氟烷基物质（PFAS）含量表明配方没有变化

在2019年夏季，从挪威最大的体育用品商店之一购买了11种最畅销的氟化滑雪蜡产品，并在不久后分析了一整套26种全氟和多氟烷基物质（PFAS）。已显示蜡包含各种全氟烷基酸，包括具有最多25个碳的全氟烷基羧酸。特别令人关注的是，发现分析的11种滑雪润滑产品中有9种的全氟辛酸（PFOA）水平高于25 ng g ^-1的欧盟限值，该限值已于4^日生效。2020年7月。全氟辛烷磺酸含量最高的滑雪蜡的浓度比欧盟的限制高1215倍。尽管一些滑雪蜡生产商已经表明他们已改用含有基于较短全氟烷基链的化学物质的配方，但分析结果表明并非如此。
