摘    要:将马尾松、赤桉、甜叶桉树和锦熟黄杨四种木柴,使用普通家用木柴燃烧加热炉在两种条件下进行燃烧,采集燃烧所排放的颗粒物样品并分析,获得了颗粒物中多环芳烃(Polycyclic Aromatic Hydrocarbons简写为PAHs)的排放因子及单个多环芳烃化合物的分布规律。结果显示:在颗粒物中检测出的多环芳烃化合物主要是分子量较大并被称为基因致毒性类的多环芳烃化合物,实验还发现:在四种木柴中,马尾松具有最高的多环芳烃化合物的排放因子,其次是赤桉和锦熟黄杨,最低的是甜叶桉树。两种不同的燃烧条件相比,慢燃烧比快燃烧所产生的总多环芳烃化合物和基因致毒性多环芳烃化合物的量都要高。

关 键 词:多环芳烃  基国致毒性多环芳烃  颗粒物  排放因子

Abstract:Four kinds of wood including pine, red gum, sugar gum and yellow box were burned under two conditions in a domestic wood heater. By sampling and analyzing particulate matter emitted from wood burning, PAHs emission factors and individual PAHs profiles have been obtained. The results shown PAHs detected in particulate matter were mostly with heavier molecular weights and were so called genotoxic PAHs. It was found that pine had the highest PAHs emissions among the four wood species, followed by red gum and yellow box, sugar gum had the lowest PAHs emissions. Total PAHs and total genotoxic PAHs from slow burning condition clearly showed higher than that from fast burning conditions. Except for red gum, it was found that all the PAH species were very well correlated to each other for yellow box . sugar gum and pine under slow burning.
Keywords:polycyclic aromatic hydrocarbons (PAHs)  genotoxic PAHs  particulate matter  emission factor
