全氟辛烷磺酸(PFOS)是一种全氟分子，最近在非工业接触者的血清中被发现。在这项研究中，对来自佛罗里达、加利福尼亚州和阿拉斯加沿海水域、波罗的海北部、北极(Spitsbergen)和加拿大黑貂的15种海洋哺乳动物的247个组织样本进行了全氟辛烷磺酸分析。在包括北极水域在内的大多数地点的海洋哺乳动物的肝脏和血液中检测到全氟辛烷磺酸。在肝脏和血液中发现的全氟辛烷磺酸的最高浓度分别是来自佛罗里达州萨拉索塔湾的宽吻海豚的1520 ng/g湿重，以及来自波罗的海北部(波提尼亚海)的环状海豹的475 ng/mL。在所分析的样品中，观察到海洋哺乳动物中全氟辛烷磺酸浓度随年龄的增加而增加。全氟辛烷磺酸在来自北极水域的哺乳动物中的出现表明，包括偏远地区在内的全氟辛烷磺酸在全球范围内广泛分布。
Perfluorooctane sulfonate (PFOS) is a perfluorinated molecule that has recently been identified in the sera of nonindustrially exposed humans. In this study, 247 tissue samples from 15 species of marine mammals collected from Florida, California, and Alaskan coastal waters; the northern Baltic Sea; the Arctic (Spitsbergen); and Sable I sl a nd in Canada were analyzed for PFOS. PFOS was detected in liver and blood of marine mammals from most locations including those from Arctic waters. The greatest concentrations of PFOS found in liver and blood were 1520 ng/g wet wt in a bottlenose dolphin from Sarasota Bay, FL, and 475 ng/mL in a ringed seal from the northern Baltic Sea (Bothnian Sea), respectively. Mo age-dependent increase in PFOS concentrations in marine mammals was observed in the samples analyzed. The occurrence of PFOS in ma rin e mamma Is from th e Arctic waters suggests widespread global distribution of PFOS including remote locations.
