摘　　要：随着全球工业的发展及人类活动的频繁,温室气体的排放量正在逐年增加,直接影响到人类赖以生存的大气质量。因此温室气体对环境的影响已引起了各国政府的高度重视,成为国际上重大环保问题。电解铝过程中会排放温室气体——全氟化碳(PFCs),美国、澳大利亚、加拿大等国家在1990年就开始对铝冶炼过程中排放的PFCs开展研究,我国在这一方面开展的研究工作较少。本文介绍了PFCs的危害和评估方法,铝冶炼过程中PFCs的产生和排放机理,国外铝行业减少全氟化碳排放采取的措施,这些经验对我国铝工业PFCs的减排有借鉴作用。The air in which we human survive is being increasingly atfected by greenhouse gas emissions since global industries are developing last and more human activities occur. High attention thus is being paid to how greenhouse gas influences the environment by national governments, which has become an international environmental issue. It is known that Perfluorocarbon compounds （PFCs） are released from primary aluminium production. And researches on PFCs has been done in the United States, Australia, Canada etc. since 1990s. However, not much work has been done in our country . In this paper, negative impacts and evaluation methods of PFCs, the mechanism of PFCs＇ coming into being during aluminium production and its emitting, and techniques taken by foreign manufacturers for solution of PFCs problem is presented, which could be helpful to domestic aluminiurn industry as a good reference for PFCs emission.
