[Spatial Distribution and Source of Perfluorinated Compounds in Urban Soil from Part of Cities in Anhui Province, China].

In order to explore the spatial distribution and source of perfluorinated compounds (PFCs),eleven mixed urban soil samples were collected from 7 cities in Anhui Province in 2013.Fifteen individual PFCs were detected by ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS),and principal components analysis was used to trace the different sources of PFCs in urban soil.The results showed that the total concentration of PFCs (Σ) ranged from 1.
