A study on the perfluorinated compounds pollution in Meiliang Bay,Taihu Lake

The pollution level and spatial distribution of perfluorinated compounds (PFCs) in surface water samples collected from Meiliang Bay of Taihu Lake were studied by using Ultra performance liquid chromatography coupled with triple quadrupole Tandem Mass Spectrometry (UPLC-MS /MS).The total PFCs concentrations in surface water from Meiliang Bay ranged from 50.06 ng·L-1 to 87.53 ng·L-1 with an average of 66.57 ng·L-1.Perfluorohexanoic acid (PFHxA),perfluorooctanoic acid (PFOA),and perfluorooctane sulfonate (PFOS) were the major PFCs in the Meiliang Bay,Taihu Lake,with ranges of 17.34 ～ 32.52 ng·L-1,7.26 ～15.57 ng·L-1,and 3.47 ～8.06 ng·L-1,respectively.These three PFCs accounted for 59.33% of the total amount of PFCs.Higher total PFC concentration was found in the east part than the west part of Meiliang Bay.This might be due to the different PFC sources and hydrodynamics of Meilaing Bay.
