Abstract

Perfluoroalkylated substances (PFASs) are a class of synthetic chemicals used in a wide range of processes and products due to their unique physicalchemical properties. Through intake of PFASs via food or several consumer products, humans can be exposed. Long-chain PFASs have been associated with adverse effects in laboratory animals, and there is also evidence for adverse health effects in humans. Although investigations of human exposure are mainly conducted in blood samples, some studies have shown that especially short-chain PFASs can be detected in human urine. In the present study, a sensitive analytical method was adapted for the measurement of 12 PFASs in human urine samples by HPLC-MS/MS. For verifying this method, concentrations in 11 male and female participants aged 25-46 years were analysed. In the study population, ranges of urinary PFASs concentrations were n.d.- 8.5 ng/l for perfluoropentanoic acid, <LOQ-3.0 ng/l for perfluorohexanoic acid, n.d.-1.8 ng/l for perfluorohexane sulphonate, n.d.-0.99 ng/l for perfluoroheptanoic acid, 0.79-5.1 ng/l for perfluorooctanoic acid, <LOQ-4.9 ng/l for perfluorooctane suphonate, and <LOQ-0.57 ng/l for perfluorononanoic acid. For the other investigated PFASs, no urinary exposure could be identified in any of the samples. The present study shows that several shortchain PFASs are detectable in human urine.
