Perfluorinated Compounds in Water, Sediment and Soil from Guanting Reservoir, China

摘要

Concentrations of 12 perfluorinated compounds (PFCs) were measured in 21 representive water, sediment and soil samples from Guanting Reservoir and vicinity. Perfluorooctanoic acid (PFOA) was the predominant PFCs with concentrations of 0.55-2.3 ng/L, < LOQ to 0.68 ng/g dw and < LOQ to 2.8 ng/g dw in water, sediment and soil, respectively. Perfluorododecanoic acid (PFDoA) was frequently detected in solid matrices, with concentrations of < LOQ to 0.18 ng/g dw in sediment and 0.13-0.26 ng/g dw in soil. PFCs were detected in all environmental matrices sampled, but concentrations found throughout the watershed were less than those reported from other locations.
