据我们所知，这是关于韩国工业化地区海洋生物体内全氟辛烷磺酸和其他全氟烷基酸浓度的首次报告。测定了韩国始花湖三种鱼类（鲻鱼、鲱鱼和石斑鱼）和三种海洋无脊椎动物（蓝蟹、牡蛎和贻贝）中八种全氟辛酸的浓度。据报告，这一地区的水和邻近的工业废水中全氟辛烷磺酸的浓度相对较高。全氟辛烷磺酸是海洋生物体内占主导地位的全氟辛烷磺酸，大多数全氟辛烷磺酸的浓度高于所有其他全氟辛烷磺酸的总和。鱼类肝脏和血液中全氟辛烷磺酸的平均浓度分别为8.1 × 10 - 6和3.6 × 10 - 6纳克/克（湿重）。鱼类体内也发现了全氟羧酸，但其浓度比全氟辛烷磺酸低10倍。在鱼类中测得的全氟乙酸中，长链全氟十一烷酸（PFUnA）的浓度最高。蓝蟹软组织中的全氟辛烷磺酸浓度随着与海岸距离的增加而降低，因为工业化地区的投入物会排入石花湖。全氟辛烷磺酸是贻贝和牡蛎中唯一可检测到的全氟辛烷磺酸，平均值分别为0.5 ± 0.2纳克/克（湿重）和1.1 ± 0.3纳克/克（湿重）。鱼类肝脏和血液中PFUnA的浓度与全氟癸酸（PFDA）呈正相关，这表明该地区这两种PFCA的共同来源。以石花湖鱼类为例，所开发的鱼类危害因子均小于1.0。
To our knowledge, this is the first report of concentrations of perfluorooctanesulfonate (PFOS) and other perfluoroalkyl acids (PFAs) in marine organisms from the industrialized region of Korea. Concentrations of eight PFAs were determined in three species of fish (mullet, shad, and rockfish) and three species of marine invertebrates (blue crab, oyster, and mussel) from Lake Shihwa, Korea. This is an area in which relatively great concentrations of PFAs in water and in adjacent industrial effluents have been reported. PFOS was the dominant PFA in marine organisms and most PFOS concentrations were greater than the sum of all other PFAs. The mean concentrations of PFOS were 8.1 × 10 and 3.6 × 10 ng/g, wet weight in liver and blood of fish, respectively. Perfluorocarboxylic acids (PFCAs) were also found in fish, but their concentrations were 10-fold less than those for PFOS. Of the PFCAs measured in fish, concentrations of the longer-chain perfluoroundecanoic acid (PFUnA) were the greatest. Concentrations of PFOS in soft tissues of blue crabs decreased as a function of distance from the shore where inputs from the industrialized areas are discharged into Lake Shihwa. PFOS was the only PFA detectable in mussels and oysters with a mean of 0.5 ± 0.2 and 1.1 ± 0.3 ng/g, wet weight, respectively. Concentrations of PFUnA were positively correlated with perfluorodecanoic acid (PFDA) in both the liver and blood of fish, which suggests a common source of these two PFCAs in this area. Hazard quotients developed for fish species were all less than 1.0 for fish collected in Lake Shihwa.
