分析了从日本和韩国采集的鸟类肝脏（n = 83），以确定全氟辛烷磺酸盐（PFOS），全氟辛烷磺酰胺（FOSA），全氟辛酸（PFOA）和全氟己烷磺酸盐（PFHS）的浓度。在所分析的95%的鸟类肝脏中发现了全氟辛烷磺酸，其浓度高于定量限（10纳克/克湿重）。在神奈川县相模河中一只普通鸬鹚的肝脏中发现了最高浓度的全氟辛烷磺酸，其浓度为650纳克/克（湿重）。日本和韩国鸟类肝脏中的全氟辛烷磺酸浓度在美国和某些欧洲国家报告的数值范围内。在5-10%的分析样品中发现了PFOA和PFHS。鸟类肝脏中全氟辛酸和全氟辛烷磺酸的最高浓度分别为21和34纳克/克（湿重）。在日本相模川采集的所有鸬鹚样本（n = 10）中均发现FOSA。鸬鹚肝脏中FOSA的最大浓度为215 ng/g（湿重）。从相模川采集的鸬鹚体内的全氟辛烷磺酸和FOSA浓度之间没有显著相关性。这些结果表明FOSA的分布是局部的。在鸟类中，氟化物浓度没有年龄或性别特异性差异。(C)2002爱思唯尔科技有限公司。保留所有权利。
Livers of birds collected from Japan and Korea (n = 83) were analyzed to determine the concentrations of perfluorooctanesulfonate (PFOS), perfluorooctanesulfonamide (FOSA), perfluorooctanoic acid (PFOA) and perfluorohexanesulfonate (PFHS). PFOS was found in the livers of 95% of the birds analyzed at concentrations greater than the limit of quantitation (LOQ) of 10 ng/g, wet weight. The greatest concentration of PFOS of 650 ng/g, wet weight, was found in the liver of a common cormorant from the Sagami River in Kanagawa Prefecture. Concentrations of PFOS in bird livers from Japan and Korea were within the ranges of values reported for those from the United States and certain European countries. PFOA and PFHS were found in 5-10% of the samples analyzed. The greatest concentrations of PFOA and PFHS in bird livers were 21 and 34 ng/g, wet weight, respectively. FOSA was found in all the samples (n = 10) of cormorants collected from the Sagami River in Japan. The greatest concentration of FOSA in cormorant liver was 215 ng/g, wet weight. There was no significant correlation between the concentrations of PFOS and FOSA in cormorants collected from the Sagami River. These results suggested that the distribution of FOSA is localized. No age-or gender-specific differences in fluorochemical concentrations could be discerned in birds. (C) 2002 Elsevier Science Ltd. All rights reserved.
