Screening of persistent halogenated compounds in human adipose tissue and blood from Sweden (engelsk)
Abstract [sv]

To expand our monitoring focus and to make complementary additions to the POPs traditionally measured we undertook a POP screening study of human tissue representative for Swedish adults in 2007. Among the compounds assessed in this study are several classes of organohalogen contaminants, such as polychlorinated dibenzo-p-dioxins and furans (PCDD/Fs) and their brominated homologues (PBDD/Fs), polychlorinated biphenyls (PCBs) and their hydroxylated metabolites (OH-PCBs), polybrominated diphenyl ethers (PBDEs) and other bromine containing compounds, a number of organochlorine Stockholm Convention pesticides including toxaphene, and several recently identified perfluorinated chemicals (PFCs). The analytical techniques used were based on various GC and HPLC massspectrometry applications after clean-up and fractionation of blood and adipose tissue samples. The profile of the PCDD/F in 2007 is considered to be unchanged since the 90’s. The shift in congener profile from BDE #47, earlier being the dominant congener in human tissues, to BDE# 153 being dominant is confirmed in this study. Levels of PCBs are lower in this study group in relation to earlier fish consumers’ levels. Six individual PFCs were detected in the blood samples analysed. PFOS was detected at the highest concentration, with a geometric mean of 16 ng/ml, followed by PFOA, 2,4 ng/ml, PFHxS, PFNA, PFDA and PFUnDA were present at similar levels. There is a need to further investigate individual exposures to PFCs and identify high exposure groups. Brominated PBDFs were found in human adipose at concentrations of 0.27-2.24 pg/g, being the first results on a larger material of the general population in Sweden. The screening of a larger sample seize of human adipose tissue revealed several unknown, bromine containing POPs. Both smaller and larger bromine containing compounds besides the known BDEs were found. Positive identification of these compounds will require authentic standards and high resolution GC/MS analysis.
