　　An investigation of atmospheric fine particle(PM2.5)from Shanghai,Nanjing and Ningbo in the Yangtze River Delta was conducted during Aug 2014 and Apr 2015.Organic species including C8 to C40 n-alkanes were determined by using GC-MS technique to evaluate organic aerosols' spatiotemporal variations and their sources.The results showed that the averaged concentrations of total n-alkanes in Shanghai,Nanjing and Ningbo were 101.1,128.2 and 241.1 ng m-3,respectively.
