Abstract

Abstract: Aquatic biota including fish, shrimp and bivalves were collected from the Yellow River Delta (YRD), China to investigate the levels, composition profile and dietary exposure of polybrominated diphenyl ethers (PBDEs), decabromodiphenyl ethane (DBDPE) and dechlorane plus (DP). The concentrations of PBDEs, DBDPE and DP in the organisms ranged from 5.3 to 149, not detected (nd) - 49, and 0.5–29 ng/g lipid weight, respectively. Higher levels of PBDEs and DP were found in mullet ( Liza haematocheila ).PBDEs were the major pollutants and BDE 209 was the predominant congener of PBDEs suggesting the great production and application of deca-BDE in YRD. The average f anti values for different species were similar to or a little lower than that of the commercial DP, suggesting syn -DP might be selectively accumulated by the organisms. The estimated daily intake values of HFRs suggested consuming fish was the main pathway for the exposure of halogenated flame retardants. Highlights: PBDEs, DBDPE and DP were determined in aquatic species from the Yellow River Delta. PBDEs were the predominant pollutants in organisms. The PBDEs pollution might ascribe to the production and usage of deca-BDE mixtures. Fanti values were in line with the minimum value of the DP commercial products. Local citizens would intake more HFRs by consuming fish.
