Brominated flame retardants (BFRs) in waste electrical and electronic equipment (WEEE) plastics and printed circuit boards (PCBs)

摘要

Two kinds of BFRs in three WEEE plastics(cell phone shells,computer housings and TV housings) and PCBs were detected with GC/MS.The results showed the plastics used as mobile phone shells had no BFRs.TBBPA was only found in computer housings.Among PBDEs,congeners of heptabromodiphenyl ether,octabromodiphenyl ether and nonabromodiphenyl ether were frequent ones,and detected in both TV housings and computer housings.But the contents of N9BDE were lower than the other two,only 180 mg/kg and 5.3 mg/kg in computer housings and TV housings respectively,while pentabromodiphenyl ether and hexabromodiphenyl ether were determined in PCBs.
