Kurzfassung:
Polybrominated diphenyl ethers (PBDEs), especially pentaBDE and decaBDE have been extensively used as flame retardants in plastics of most electronic equipment. However, PBDE congeners have been found in the environment, in wildlife and in human body worldwide with evidences that they pose risks both to human health and to the entire ecosystem. China has become an important pentaBDE and decaBDE production country because of the increasing domestic demand due to rapid development of electronic industry in recent years. Although pentaBDE was phased out in 2004, decaBDE still remains in production and is used in electrical industry. Additionally, large amounts of plastics containing these pollutants from waste electrical and electronic equipment (WEEE) are generated in China each year and their disposal has been a vital environmental challenge. Machaniclal recycling, fedlock recycling and landfilling are three main means of disposal of WEEE plastics. This article reviews the production of PBDEs, the amounts of WEEE and the disposal of WEEE plastics worldwide, with a special focus on China. The state of the emission of PBDEs and highly toxic polybrominated dibenzo dioxins/furans in the process of disposal is summed up based on previous studies. This article recommends that mechanical recycling should be the main means of disposal of WEEE recycling with regards to the summaries, the current practices and the status in China.
