摘 要: 大气中的多环芳烃(polycyclic aromatic hydrocarbons,PAHs)严重危害人体健康,民用燃煤是其最重要的来源。本研究系统地总结了民用燃煤排放PAHs对人体健康的危害、排放特征(包括成分谱和排放因子)及监测方法等研究现状,并指出了目前常用的稀释通道采样方法在应用于燃烧源采样时,稀释倍数对半挥发性组分的影响。同时提出了未来对民用燃煤排放PAHs研究的关注焦点。本研究可为民用燃煤排放PAHs的颗粒物监测、风险评估、来源解析、清单构建等提供参考和借鉴。
关 键 词: 大气化学;民用燃煤;综述;多环芳烃;源排放;健康风险

Abstract: Atmospheric polycyclic aromatic hydrocarbons (PAHs) exhibits negative impacts on human health with domestic coal combustion as the most important source. This paper systematically summarizes the current studies including health impacts of PAHs emitted from domestic coal combustion, their emission characteristics (emission source profiles and factors) and widely used monitoring methods. The paper also analyzes the influence of dilution ratio on the semi-volatile compounds when using the dilution tunnel sampling system. The research focuses in the future is also proposed. This paper is useful for emitting PAHs from domestic coal combustion by monitoring the particulate matters, risk assessment, source apportionment and emission inventory establishment.
Key words: atmospheric chemistry; domestic coal combustion; review; polycyclic aromatic hydrocarbons; source emission; health risk
