| 摘 要： | 按照季节变化，采集峰峰矿区三个采样点的降尘样品，并对其进行实验分析，得出峰峰矿区降尘中正构烷烃分布主要为后峰型及双峰型,均以C29为主峰碳,CPI值为1.54 - 10.54；通过分析认为该区春夏秋季降尘中正构烷烃主要来源于高等植物、花粉等生物有机质，冬季主要来源于煤等化石燃料燃烧,从春季到冬季生物质来源逐渐减少,化石燃料来源逐渐增多。

| Abstract: | Experiment analysis were carried out on dustfall samples which were collected from three sampling points in Fengfeng District according to the changes of seasons. The results showed that the distributions of n-alkanes in dustfall can be mainly divided into two types with the CPI values ranging from 1.54 to 10.54, including behind peak type and dual distribution type. Both of them take C29 as main carbon. N-alkanes in dustfall mainly come from fossil combustion such as coal when in winter but come from bio-organic matter like higher plant and pollen in the other seasons. Source of bio-organic matter are gradually reduced from spring to winter, while fossil combustion sources are increased. |
