Despite the increase in production, usage, and discharge of organophosphate flame retardants (OPFRs), little information is available about their bioaccumulation trophic transfer marine food web. In this study, seawater, sediment, species (10 fish 9 invertebrate species) collected from Laizhou Bay, North China, were analyzed to investigate levels, bioaccumulation, biomagnification OPFRs a Of 20 screened for, 17 quantifiable organisms. The ∑OPFRs concentrations ranged 0.2 28.4 ng/L 0.1-96.9 ng/g dry weight 21.1-3510 lipid Benthic accumulated more than pelagic invertebrates. A linear significant factors with increasing lipophilicity was observed (R2 = 0.63, p < 0.05), biota-sediment accumulation increased hydrophobicity up log KOW 4.59 then decreased KOW. Trophic magnification 1.06 2.52, indicating potential This study provides important insight into suggests further investigation on group chemicals.
