AB  - Three regulated halogenated flame retardants (HFRs), i.e., polybrominated 
      diphenyl ethers (PBDEs), polybrominated biphenyls (PBBs) and 
      hexabromocyclododecanes (HBCDs), and several alternative HFRs (AHFRs) including 
      Dechlorane Plus (DP), decabromodiphenyl ethane (DBDPE), and 
      1,2-bis(2,4,6-tribromophenoxy) ethane (BTBPE), were investigated in the 
      home-produced eggs from three recycling sites and a reference site in an 
      electronic waste (e-waste) recycling region, South China. Mean levels of HFRs in 
      eggs from the recycling sites ranged 2640-14100, 700-1620, 44-350, and 720-3920 
      ng/g lipid weight for  summation operatorPBDEs,  summation operatorPBBs,  summation operatorHBCDs, and  summation operatorAHFRs, respectively, which were 
      one to two orders of magnitude higher than those examined in the reference site. 
      PBDEs were the predominant HFR in those eggs, with contributions >50% to the 
      total HFRs; followed by PBBs and the AHFRs (contributing 14-22% in average). The 
      alpha-HBCD was the predominant diastereoisomers of HBCDs, with preferential 
      enrichment of the (-)-enantiomer in most of the eggs; but no significant 
      stereoselective enrichment of the DP isomers was observed in these eggs. The 
      average estimated daily intakes (EDIs) of PBDEs, PBBs, HBCDs, and the AHFRs via 
      eggs from the recycling sites ranged 4200-20000, 1120-2440, 80-490, and 970-4530 
      ng/day, respectively, which were one to two orders of magnitude higher than those 
      reported from other parts of the world. The potential adverse effects of these 
      HFRs to human health in the e-waste sites should be further investigated. This is 
      the first report on the isomer compositions of DP and the chiral signatures of 
      HBCDs in hen eggs.
