摘要
辨识室内颗粒物来源与分析室内颗粒物元素特征称为源辨识与源解析,是进行室内空气污染控制与净化的理论依据与前提条件。本文通过对室内空气品质(IAQ)模型进行理论分析,阐明了室内外污染源与室内颗粒物浓度之间的关系。指出室内颗粒污染物研究应根据污染源已知与未知两种情况进行讨论,并针对不同的情况分别采用源辨识与源解析技术。
Particulate matter （PM） effecting on human health has been extensively examined in an amount of epidemiological studies. Yet people spend a great fraction of their time indoors, and indoor pollutants can be different from those outdoors. Indoor PM concentrations are associated with both indoor and outdoor pollution sources. The source characterization and source contribution are of significance to predict the indoor PM concentration and also to implement source control. This study mainly focuses on how to identify the pollutant sources when the sources are specific or not. Indoor air quality （IAQ） model is used to analyze the concentration relationship between indoor and outdoor PM. And different technologies on source identification and source apportionment are introduced and compared.
