Recent developments in source apportionment modeling of volatile organic compounds (VOCs) include receptor modeling (RM) applications to "total" (indoor and outdoor) exposure assessment for source of VOC. Source fingerprints are available for major VOC sources such as gasoline vapor, automobile exhaust, refinery emissions, cleaning solvent vapors, printing inks, and waste-water treatment facilities. The relative proportion of each VOC species in the source fingerprint enables the RM method, through a least squares analysis, to identify each source's presence and quantify its contribution to ambient air concentrations. Sampling periods and locations may be selected to represent microenvironmental exposures. Receptor modeling has direct applicability to determining the relative contribution of gasoline vapors to VOC exposures in the general population.
挥发性有机化合物(VOCs)源解析模型的最新进展包括受体模型(RM)在VOC源“总体”(室内和室外)暴露评估中的应用。主要VOC源(如汽油蒸气、汽车尾气、炼油厂排放物、清洁溶剂蒸气、印刷油墨和废水处理设施)的源指纹图谱是可得的。源指纹图谱中每种VOC物质的相对比例使得RM方法能够通过最小二乘法分析来识别每种源的存在,并量化其对环境空气浓度的贡献。可以选择采样周期和地点来代表微环境暴露情况。受体模型在确定汽油蒸气对一般人群VOC暴露的相对贡献方面具有直接适用性。
