NILU has, on behalf of the Norwegian Environment Agency, performed chemical analyses of a selection of additives in plastic products. The goal was to identify content and migration of the chemical additives in and from the products to air and surfaces of the products at room temperature. The plastic products covered extension cord, sockets, flooring, wall papers, upholstery, PC-mouse and PCs. Targeted chemicals were organophosphorous flame retardants (OPFRs), brominated flame retardants (BFRs) including TBBPA, and chlorinated substances. TPHP (triphenyl phosphate) was detected in most sample types, but the highest concentrations were found for TBEP (tris(2-butoxyethyl)phosphate. The highest number of compounds were detected in the PC-mouses and high levels were also found in the surface wipes on PC-mouses. None of the targeted compounds were detected in the air samples.
