Characteristics and Source Apportionment of n-Alkanes in PM2.5 in Zhengzhou
摘要
Abstract
In order to investigate the pollution characteristics and potential sources of n-alkanes in PM2.5 in Zhengzhou,a set of PM2.5 samples were collected during October 2014 to July 2015 in Zhengzhou University campus.n-Alkanes (C8~C40) were analyzed by GC-MS.Cmax,CPI,wax content and PMF were used to identify potential sources of n-alkanes,and apportion the contributions of each possible source.The results showed that the average concentrations of n-alkanes in PM2.5 were 272±78,392±203,177±59 and 89±24 ng/m3 in autumn,winter,spring and summer respectively,with a distinct seasonal variation of winter>autumn>spring>summer.n-Alkanes in PM2.5 in Zhengzhou were mainly from fossil fuel burning including coal combustion and vehicle emissions.关键词
