摘要将差分光学吸收光谱法（DOAS）与传统的吸附进样法和气相色谱法测定空气中的芳烃进行了比较。在瑞士和瑞典的苯和甲苯浓度分别高达20和40 μg m−3的地点进行了测量。所测定的碳氢化合物主要来源于交通尾气。结果表明，所研究的DOAS版本是连续监测空气中浓度高于10 μg m−3的苯和甲苯的通用工具。
Abstract A recently introduced technique based on differential optical absorption spectroscopy (DOAS) was compared with conventional adsorption sampling and gas chromatography for the determination of aromatic hydrocarbons in air. Measurements were made in Switzerland and Sweden, at sites with benzene and toluene concentrations up to 20 and 40 μg m−3, respectively. The hydrocarbons determined originated mainly from traffic exhaust. The results demonstrate that the version of DOAS studied is a versatile tool for continuous monitoring of benzene and toluene in air at concentrations higher than 10 μg m−3.
