摘要：

The solvent-extractable compounds (lipids) of aerosol samples, which were collected from a western suburb of Beijing, in the city of Guiyang and on the outskirts of Guangzhou, P.R. China, using a standard high volume air sampler, were investigated to determine the distributions of homologous compounds and biomarkers. These preliminary results show that all samples contain aliphatic hydrocarbons including n-alkanes, steranes and triterpanes, derived from both biogenic sources (vascular plant wax input) and fossil fuel contamination (coal, crude oil, ect.). Polynuclear aromatic hydrocarbons, which are considered to be combustion products from fossil fuels such as petroleum and, especially in this case, coal burning, are also widely distributed in all samples. Oxygenated compounds (e.g. alkanoic acids, alkanones and alkanols) are present as major fractions and are derived from mainly natural sources. Furthermore, some compositional differences are observed for the organic compounds in samples from different heights above ground. This is interpreted to be due to dilution at higher levels of locally generated aerosol with upper air aerosol transported over longer distances.
