Abstract：The contamination status and spatial distributions of perfluorinated compounds (PFCs) were investigated in waters of the Grand Canal in eastern China during 2014. A total of 41samples of surface waters were collected. High performance liquid chromatography/negative electrospray ionization-tandem mass spectrometry (HPLC/ESI-MS/MS) was used to identify and quantify PFCs. The total concentrations of PFCs (∑PFCs) ranged from 7.4~153.5ng/L, generally showing a trend of deceasing from south to north. ∑PFCs were greater in Hangzhou-Jiaxing section than those in other sections. For the northern Canal, the highest ∑PFCs occurred in Dezhou section. PFOA was the prevalent PFC in the southern part of the Canal and its prevalence decreased in general in the northern part. Comparisons are made between the population density and the gross domestic product (GDP) of cities or prefectures located in the Grand Canal sampling areas in 2014 and the corresponding average ∑PFCs in waters.
