The ashes under dust catcher of typical power plants in Yangquan was collected and the contents of elements, irons, EC (elemental carbon) and OC (organic carbon) were measured in PM₂. The characteristics of its chemical composition was studied and the degree of similarity of coal dust's source profiles of PM₂.₅ between Yangquan and other cities were compared using the coefficient of divergence method. The result indicated that the main chemical components of PM₂.₅ from the coal dust were SO₄²⁻,Ca, NO₃⁻, OC, EC, Al, Si, Na, Fe, Mg and Cl⁻, accounting for 57.22% of the total mass. The enrichment factor of Pb in PM₂.₅ of coal dust was the largest with a significant enrichment condition, reaching 10.66-15.91. The coefficient of divergence of source profiles of PM₂.₅ between blind coal and fault coal was 0.072, so it was believed that they must be similar. Compared with other cities, the chemical composition of coal dust in Yangquan had specificity, in particular, the content of Ca was obviously higher than those in other domestic cities.
收集了阳泉典型电厂除尘器下的灰样，测定了PM₂中元素、铁、元素碳（EC）和有机碳（OC）的含量。研究了其化学成分特征，并采用离散系数法比较了阳泉与其他城市PM₂.₅煤尘源谱的相似程度。结果表明，煤尘中PM₂.₅的主要化学成分是SO₄²⁻、Ca、NO₃⁻、OC、EC、Al、Si、Na、Fe、Mg和Cl⁻，占总质量的57.22%。煤尘PM₂.₅中Pb的富集因子最大，富集状况显著，达到10.66 - 15.91。无烟煤与断层煤PM₂.₅源谱的离散系数为0.072，因此认为它们必然相似。与其他城市相比，阳泉煤尘的化学成分具有特殊性，尤其是Ca的含量明显高于国内其他城市。
