摘要
研究了大气中半挥发性有机物(SVOC)在滤膜、聚氨基甲酸酯泡膜(PUF)和XAD-2三层上的分布,青岛市大气中SVOC的组分和主要有机物的浓度。大气中的SVOC部分四环和五环以上的多环芳烃主要吸附在滤膜层,而大部分SVOC吸附在PUF层,XAD-2吸附的有机物主要是三甲苯和单体萘。冬季大气中主要的有机物是四环以下PAHs的烷基取代物和多种烷基酚,酚类化合物在冬夏两季的变化最大,夏季中检不出酚类化合物,酚类化合物主要来源于燃煤,而PAHs及烷基取代物来源于燃煤和交通。冬夏两季大气中均能检出与交通有关的己内酰胺。
Distribution of semi-volatile organic compounds in filter,PUF and XAD-2 and component,concentrations of SVOC in air was studied. Some four cycle and all more than five cycle PAHs were adsorbed in filter. a majority of SVOC were adsorbed in PUF, which include 2,3 and some 4 cycle PAHs and its methyl substitution derivate,phenol and its methyl substitution derivate. Phenol compounds come from coal burned. PAH and substitution derivate come from coal burn and transportation. Caprolactam can be detected in urban air in winter and summar.
