Research Progress of Source Apportionment for Saturated Hydrocarbons and Polycy clic Aromatic Hydrocarbons in Ambient Particular Matter in China

综述了利用奇偶优势指标、最高峰碳数指标以及色谱峰型特征来判识正构烷烃的来源和利用浓度比值法、化合物的轮廓图特征法、多元统计方法和化学质量平衡法判识多环芳烃的来源,并指出这些方法特点。

There are various methods to study on source apportionment for hydroc arbons in ambient particulate matter. Source apportionment methods such as carbo n preference index (CPI, ∑Codd/∑Ceven), carbon number maxi mum (Cmax, the carbo n number with the largest peak area in the chromatogram) and characteristics of chromatography peaks for saturated hydrocarbons; and ratio method, characteristi c of source profile, multivariate regression statistics and chemical mass balanc e (CMB) receptor model for apportioning polycyclic aromatic hydrocarbons are rev iewed. The research status and typical case studies are discussed.
