Blood serum concentrations of POPs in Swedish adolescents participating in the national representative study riksmaten adolescents 2016–2017. POPs data presented as arithmetic means (5th−95th percentile); chlorinated and brominated POPs presented per volume in blood serum (ng/L wet weight); PFASs data presented in blood serum (µg/kg wet weight).
