多环芳烃是具有多个苯环的芳香族有机化合物，具有致癌、致畸、致突变作用。由于PAHs种类繁多，分布范围广，与人类的日常生活关系密切，且难降解，因此在环境中能存在很长时间，所以人们对环境中的PAHs更加关注。本文系统地综述了大气、水体、土壤和污泥中多环芳烃的前处理技术。%PAHs are a number of aromatic ring aromatic organic compounds, with cancer, teratogenic and the mutation role. In recent years ,because of PAHs variety, its wide distribution, the daily life of the close relationship between human and difficult degradable, and its long-term existence in the environment, people pay more attention to the environment of PAHs. This paper systematically reviewed the air, water, soil and sludge PAHs in the preparation technology.
