초록

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