水貂和水獭是其水环境的良好集成者，也是确定环境污染物暴露程度的有用哨兵物种。在这项研究中，对美国不同地点采集的水貂和水獭的肝脏中的全氟辛烷磺酸(PFOS；C8F17SO3-)、全氟辛烷磺酸(FOSA；C8F17SO2NH2)、全氟己烷磺酸(PFHxS；C6F13SO3-)和全氟辛酸(PFOA；C7F15CO2-)进行了测定。在所有被分析的水貂肝脏中都发现了全氟辛烷磺酸。FOSA、PFHxS和PFOA的出现频率较低。在水貂肝脏中测得的全氟辛烷磺酸最大浓度为5140 ng/g(湿重)。水貂肝脏中FOSA、PFHxS和PFOA的最高浓度分别为590、39和27 ng/g湿重。水貂肝脏中全氟辛烷磺酸的浓度与全氟辛烷磺酸或全氟辛烷磺酸之间没有显著的正相关关系。伊利诺伊州水貂肝脏中全氟辛烷磺酸浓度与FOSA浓度呈正相关。全氟辛烷磺酸的浓度与水貂肝脏中的脂肪含量之间没有显著相关性。水貂肝脏中的氟化学物质浓度没有年龄或性别上的差异。在城市化和/或工业化地区附近采集的个体密度更高。从华盛顿州和俄勒冈州采集的所有河獭的肝脏中都检测到全氟辛烷磺酸，浓度从25到994 ng/g，湿重。
Mink and otters are good integrators of their aquatic environments and useful sentinel species for determining exposure to environmental contaminants. In this study, perfluorooctanesulfonate (PFOS; C8F17SO3-), perfluorooctanesulfonamide (FOSA; C8F17SO2NH2), perfluorohexanesulfonate (PFHxS; C6F13SO3-), and perfluorooctanoate (PFOA; C7F15CO2-) were measured in livers of mink and river otters collected from various locations in the United States. PFOS was found in all mink livers analyzed. Frequencies of occurrence of FOSA, PFHxS, and PFOA were less. The greatest concentration of PFOS measured in liver of mink was 5140 ng/g, wet weight. Maximum concentrations of FOSA, PFHxS, and PFOA in mink livers were 590, 39, and 27 ng/g, wet weight, respectively. There were no significant positive relationships between concentrations of PFOS and PFHxS or PFOA in mink livers. Concentrations of PFOS were positively correlated with those of FOSA in mink livers from Illinois. There was no significant correlation between concentrations of PFOS and lipid content in mink livers. There were no age- or sex-related differences in the concentrations of fluorochemicals in mink livers. Greater concentrations are associated with those individuals collected near urbanized and/or industrialized areas. PFOS was detected in livers of all river otters collected from Washington and Oregon at concentrations ranging from 25 to 994 ng/g, wet wt.
