Abstract

Different sampling methods for mutagenic polynuclear aromatic hydrocarbons (PAH) are described. These methods involve either direct sampling of raw exhausts which prior to filtering are cooled in a condenser, or filter sampling of exhausts diluted in a tunnel. The relevance of gas-phase PAHs of samples from diluted exhausts is discussed; methods used are either adsorbents (XAD-2) or cryogenic condensation. The emission of benzo(a)pyrene and certain other PAHs is reported from vehicles using different fuels (gasoline, diesel, LPG, alcohols) or different emission control systems. The emission of some volatiles, such as benzene, ethylene and alkylnitrites, is also presented from different types of fuels used.

摘要

描述了用于诱变多环芳烃(PAH)的不同采样方法。这些方法包括对未经过滤先在冷凝器中冷却的原始废气进行直接采样,或对在风洞中稀释的废气进行过滤采样。讨论了稀释废气样品中气相多环芳烃的相关性;使用的方法有吸附剂(XAD - 2)或低温冷凝。报告了使用不同燃料(汽油、柴油、液化石油气、酒精)或不同排放控制系统的车辆中苯并(a)芘和某些其他多环芳烃的排放情况。还介绍了使用不同类型燃料时一些挥发性物质(如苯、乙烯和亚硝酸烷基酯)的排放情况。
