Research Progresses of Determination of Perfluorinated Compounds in Environmental Water and Solid Samples

Perfluorinated compounds (PFCs), a group of persistent organic pollutants, have been widely detected in environmental media and posed great threats to human health. The researches on environmental pollution and health risk of PFCs have become the hot subject in recent years. The advanced and reliable analytical methods for determination of PFCs are urgently needed since various homologs and isomers of PFCs are detected at trace levels (ng g(-1) or mu g L-1) in environment. At present, studies on analytical methods of trace PFCs in environmental samples have been extensively carried out in China and abroad. However, reviews which systematically discuss the sample pretreatment, analytical method, and matrix effect of determination of PFCs in complex environmental matrixes are hardly available. Therefore, the present review highlights the pretreatment methods, matrix effects, and detection techniques (especially isomers) of PFCs in environmental samples (water, sediment, sludge, soil and plant). It hopes that this review will provide valuable references for the environmental researches on PFCs.
