Transfer of persistent organic pollutants in food of animal origin – Meta-analysis of published data

The transfer of POPs in food animal origin has been studied by a meta-analysis 28 peer-reviewed articles using rate (TR) for milk and eggs bioconcentration factors (BCF) eligible tissues after establishing an adapted methodology. TRs the most toxic PCDD/Fs into were generally elevated even higher eggs. BCFs excreting adult animals varied widely between studies complicating to hierarchize or congeners, if liver fat seemed bioconcentrate more than lean tissues. Short time have clearly shown low contrarily field showing highest BCFs. growing muscle. In contrast easily bioconcentrating hexachlorinated octa- heptachlorinated congeners barely bioconcentrate. PCB was systematically high very lipophilic congeners. Highly ortho-chlorinated PCBs transferred >50% >70% 123 167 126 169 significantly less seem PBDEs except 47, 153 154. DDT its metabolites showed bioconcentration. Differences appeared but masked study effect. addition some methodologic recommendations, this analysis eggs, when exposed justifying strong monitoring areas with POP exposure.
