The report provides information on the occurrence of per- and polyfluorinated chemicals (PFASs) and alkylphenols (APs) in various product groups. For PFASs, the report analyses construction materials and industrial textiles as well as the content of short-chain APs (4tPP, 4tBP) in paints, coatings and adhesives. At the same time, the occurrence of APs in surface waters was investigated in a screening. The highest concentrations of PFASs were detected in marquee and coating samples. APs were determined in the majority of the investigated preparations. The occurrence and the detection frequency of the different APs in waters shows a very diverse picture.
