OCCURRENCES AND TRANSPORT OF PERFLUORINATED COMPOUNDS IN EAST CHINA SEA
Perfluorinated compounds (PFCs) are fully fluorinated organic compounds, which are distributed all over the world and have been found in even in remote regions far from human activities. The purposes of the study were to identify the occurrences of PFCs in East China Sea and to understand the transportation of PFCs in open sea. Surveys were conducted in East China Sea and samples were collected from surface water deep water and sediment. A solid phase extraction (SPE) coupled with HPLC-ESI-MS/MS were used. PFCs were detected in all samples indicating PFCs are the long range transport pollutant. PFCs in the aqueous phase were ranged from 716 – 3,576 pg/L. The geometric mean of PFCs concentration was 1,755 pg/L. The geometric mean of PFCs concentration in the sediment was 904 ng/g. PFOS was only predominant PFCs in the sediment accounting for more than 90％ in the samples.
