摘要
Abstract
In order to explore the sources and characteristic of the elements in PM25 during winter of Anshan,PM25 samples were collected in January 2016 and the pollution characteristics and enrichment factors of elements were analyzed Then the Factor Analysis (FA) was conducted to determine the main sources of PM25 The results showed that K,Fe,Al,Ca,Na,Mg,Zn and Pb were the main elements and accounted for 9713% of the 14 elements detected The pollution levels of Cd、Zn、Pb、As、Cu were extremely high enrichment and Ni was very high enrichment Cr、Ca、V were significant enrichment and Mg、K、Na、Fe were moderate enrichment The results indicated that the main sources of the pollution elements in PM25 during winter in Anshan were the compound pollution sources of the steel smelting,vehicle exhaust,coal combustion and construction dust by factor analysis关键词
