Abstract
Per- and polyfluorinated chemicals (PFC) have inimitable properties. They are very stable, e.g. are resistant to biotic and abiotic breakdown, and are water and grease repellent. Therefore, they are used in numerous industrial applications, such as in paper- and packaging as well as textile industry. The manufacture, use, and disposal of consumer products is an important source for exposure into the environment. The persistence of PFCs, however, is problematic for the environment. A number of PFCs can be fund ubiquitously in the environment. Findings in remote regions, in human blood and breast milk are of very high concern.
The most frequently detected PFCs are perfluorooctansulfonic acid (PFOS) and perfluorooctanoic acid (PFOA). Both of these compounds are persistent, toxic and bioaccumulative.
While the marketing and use of PFOS is prohibited with few exceptions in the EU since June 27, 2008 there is no substance specific regulation for PFOA.
Available data on PFCs in consumer products are scarce to date. Hence, more data are needed in order to get an overview on recent PFC loads and to evaluate if these data implicate further measures against PFOA with respect to a regulation according to REACH. Therefore, the Federal Environment Agency of Germany initiated an analytical screening project in 2009.
Perfluorinated sulfonic (C4, C6-C8, C10-PFSA) and carboxylic acids (C4-C14-PFCA) and fluorotelomer alcohols (4:2, 6:2; 8:2 and 10:2 FTOH) were analyzed in 118 consumer products including textiles (outdoor materials), carpets, cleaning and impregnating agents, leather samples, baking and sandwich papers, paper baking forms and ski waxes. PFCA and PFCA were analysed by LC-ESI-MS/MS, whereas FTOH were detected by GC-CI-MS.
The results show that there are consumer products with low or negligible PFSA- and PFCA-contents, such as the cleaning agents or baking and sandwich papers tested. On the other hand, high PFC levels were identified in ski waxes, leather samples, outdoor textiles and some baking papers. Moreover, the PFOS concentrations in most of the leather and carpet samples as well as some textile samples tested exceeded the regulatory threshold value of 1 ?g/m2 PFOS according to the European PFOS regulation.
