Soil, sediment, water, and biota collected from the western coast of Korea were analyzed to determine occurrence and sources of perfluorinated compounds (PFCs). PFCs were significantly concentrations of PFCs were measured in some water and biological samples, while concentrations of PFCs in soils and sediments were relatively low. The most widely detected compound was found to be perfluorooctanesulfonate (PFOS), with a maximum concentration in water of 450 ng/L and in fish of 612 ng/g, dw. PFOS concentrations in water and biota were both less than those thought to cause toxicity. However, in both cases concentrations were within a factor of 10 of the toxicity threshold concentration. Concentrations of PFCs were significantly greater downstream than those upstream on the same river, suggesting point sources. Overall, the detection of PFCs at relatively great concentrations in various environmental matrixes from this region of Korea suggests that further studies characterizing PFCs and their potential risk to both humans and wildlife are needed.
从韩国西海岸采集的土壤、沉积物、水和生物群进行了分析，以确定全氟化合物 (PFC) 的存在和来源。结果表明，在一些水和生物样本中检测到了 PFCs 的显著浓度，而土壤和沉积物中的 PFCs 浓度相对较低。最广泛检测到的化合物是全氟辛烷磺酸 (PFOS)，其在水中的最大浓度为 450ng/L，在鱼类中的浓度为 612ng/g，dw。水中和生物群中的 PFOS 浓度均低于被认为会引起毒性的浓度。然而，在这两种情况下，浓度都在毒性阈值浓度的 10 倍以内。在同一条河流的下游，PFCs 的浓度明显高于上游，这表明存在点源。总的来说，在韩国这一地区的各种环境基质中检测到相对较高浓度的 PFCs，表明需要进一步研究 PFCs 及其对人类和野生动物的潜在风险。
