摘要
为研究新余市环境受体中PM_(2. 5)化学组分特征,于2020年8月、10月、12月及2021年1月在新余市4个城区监测点位采集了PM_(2. 5)样品,分析了PM2. 5中的碳组分(OC和EC)、水溶性无机离子和无机元素等。结果显示,新余市环境受体PM2. 5的主要物质为OM,占比为27%,其次是硝酸盐、硫酸盐和铵盐,占比分别为18%、15%和12%。地壳元素占比为8%,EC约为4%。对化学组分的时空分布特征进行了分析。
In order to study the characteristics of chemical compositions in PM_(2.5) in Xinyu city,PM_(2.5) samples were collected at four urban monitoring sites in August,October,December 2020 and January 2021,in which carbon fraction,water-soluble ions and inorganic elements were determined.The results showed that the major chemical compositions in PM_(2.5) were OM(27%),NO_(3)^(-)(18%),SO_(4)^(2-)(15%),and NH+4(12%).The temporal and spatial distribution characteristics of chemical compositions were also analyzed.
