title: Polybrominated diphenyl ethers in chicken tissues and eggs from an electronic waste recycling area in southeast China.
abstract: The levels and distributions of polybrominated diphenyl ethers (PBDEs) in chicken tissues from an electronic waste (e-waste) recycling area in southeast China were investigated. Human dietary intake by local residents via chicken muscle and eggs was estimated. The mean PBDEs concentrations in tissues ranged from 15.2 to 3138.1 ng/g lipid weight (lw) and in egg the concentration was 563.5 ng/g lw. The results showed that the level of total PBDEs (sigmaPBDEs) in the chicken tissue was 2-3 orders of magnitude higher than those reported in the literature. The large difference of sigmaPBDEs concentrations between tissues confirmed that the distribution of PBDEs in tissues depend on tissue-specificity rather than the "lipid-compartment". BDE-209 was the predominant congener (82.5%-94.7% of sigmaPBDEs) in all chicken tissues except in brain (34.7% of sigmaPBDEs), which indicated that deca-BDE (the major commercial PBDE formulation comprising 65%-70% of total production) was major pollution source in this area and could be bioaccumulated in terrestrial animals. The dietary PBDEs intake of the local residents from chicken muscle and egg, assuming only local bred chickens and eggs were consumed, ranged from 2.2 to 22.5 ng/(day x kg body weight (bw)) with a mean value of 13.5 ng/(day x kg bw), which was one order of magnitude higher than the value reported in previous studies for consumption of all foodstuffs.
