摘　　要：本文讨论了城市居住区空气中苯、甲苯、二甲苯的采集、测量和来源的识别方法，分别在受污染居住区和未受污染居住区，用活性炭吸收、气相色谱法测定苯系物。通过日变化规律对比方法和各种苯系物之间浓度相关性的观察，判断居住区苯系物的来源，为环境管理和污染防治提供科学依据。Measurement and Collection of benzene, toluene and xylense in urban residential quarters air as well as the source of pollutants are discussed. The air was absorbed by charcoal from an unpolluted residential quarter and a polluted residential quarter. The samples were analyzed by gas chromatography.By means of analyzing correlations between benzene hydrocarbons, the investigation of the source of benzene hydrocarbons in residential quarters was made to provide scientific bases for environment management, prevention and treatment of pollution.
