The brominated flame retardants (BFRs) have been used in many household products such as plastics of electronicequipment, furniture, textiles to increase their flame ignition resistance. Among the mixtures of BFRs, polybrominateddiphenyl ethers (PBDEs), tetrabromobisphenol A (TBBPA), hexabromocyclododecane (HBCD) have been widely usedas commercial additive during the last decade. This study has been performed to investigate the concentration of BFRsin waste electrical and electronic equipment which has potential threat on environment and human health. We analyzedPBDEs, TBBPA and HBCD in 18 products from 2 TV manufacturing companies, 19 parts from 3 refrigerators, shreddedplastic from recycling center, 3 other plastics from recovery process, and 43 small electronics using heating source. Theconcentration of PBDEs in TVs ranged from 306mg/kg (manufactured since the year of 2000) to 145,027mg/kg(manufactured in 1983~1997). The concentration range of PBDEs in rear housing is greater than those of front cover.The concentration of TBBPA were detected from 30 to 201mg/kg and HBCD was not detected (ND) in all samples ofTV. The PBDEs concentrations in plastics of refrigerator waste were detected from ND to 445mg/kg, the concentrationof PBDEs in upper housing cover is higher than those of other parts. The concentration of PBDEs in small electronicswas not detected in most products but HBCD and TBBPA were detected several hundred ppm in 1mixer and severaldozen of ppm in 1mixer, 1 coffee port and 2 electronic rice cookers, respectively. Based on the concentrationcharacteristics of BFRs in waste electrical and electronic equipment, we will be established the environmentally soundstrategies for the management policies of the waste containing BFRs.
