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.
在官厅水库及其周边的 21 个有代表性的水、沉积物和土壤样本中，测量了 12 种全氟化合物（PFCs）的浓度。全氟辛酸（PFOA）是主要的 PFCs，其浓度分别为 0.55-2.3ng/L、<LOQ 至 0.68ng/g dw 和 <LOQ 至 2.8ng/g dw 在水中、沉积物和土壤中。全氟十二烷酸（PFDoA）在固体基质中经常被检测到，其浓度分别为<LOQ 至 0.18ng/g dw 在沉积物中，0.13-0.26ng/g dw 在土壤中。在所采集的所有环境基质中都检测到了 PFCs，但整个流域的浓度低于其他地区的报道。
