The exposure to four PFRs was assessed through hair, finger and toe nails analyses. Extraction performance of SPE Oasis Wax versus STRATA X-AW was tested. DBP reduction in the blanks was successfully achieved by a new wash step in SPE. DPhP was the major metabolite measured in finger and toe nails. Over 2 months, the female showed constant exposure to the parent PFR in finger nails.
