摘　　要：为了利用化学质量平衡 (CMB)受体模型解析煤烟尘对环境空气中多环芳烃的贡献率 ,建立煤烟尘多环芳烃成分谱是非常必要的。笔者测定了民用燃煤烟尘和工业燃煤烟尘中 13种多环芳烃的组成。对分析结果进行归一化后 ,确定了民用燃煤和工业燃煤多环芳烃成分谱 ,并进一步讨论了BaP BghiP ,BaP COR ,PYR BaP ,BeP BaP和IND BghiP的特征比值 ,以及多环芳烃的降解对其造成的影响。To evaluate the contribution of coal combustion to PAHs to airborne particulate using CMB receptor model,a study of PAHs source profile for coal combustion is necessary.After sampling,13 PAHs in the samples of coal combustion were determined by GC/MS.The source fingerprints for civil and industrial coal combustion were obtained by averaging the ratios of individual PAHs concentration to the mass of the 13 PAHs measured in this study.The characteristics of the ratios of BaP/BghiP,BaP/COR,PYR/BaP,BeP/BaP,IND/BghiP were discussed.Furthermore,the influence of reactivity of PAHs on the ratios was discussed.
