收集了与巴塞罗那大气中明确界定的冷/暖季节相对应的气溶胶样本，并在稳定的大气条件下对其进行了分级。汽油和柴油车辆排放的主要碳氢化合物在大多数颗粒物组分中都被识别出来。在定量方面，这些碳氢化合物主要存在于亚微米级分中，特别是0.56-0.96-和
Aerosol samples corresponding to well-defined cold/warm seasons in the atmosphere of Barcelona have been collected and size-fractionated during stable atmospheric conditions. A predominant hydrocarbon pattern derived from gasoline and diesel vehicular traffic emissions has been identified in most particle fractions. In quantitative terms, these hydrocarbons exhibit a predominant occurrence in the submicron fractions, particularly the 202 for the 0.56-0.96- and
