Perfluorooctanoate (PFOA) are environmental contaminants posing special public health concerns because of their long-term persistence and bioaccumulation in the environment. Fluorotelomer alcohols are volatile and may undergo long-range transport. Air samples were collected at five sites in the Keihan area, Japan: Sakyo, Morinomiya and three sites in Higashiyodogawa. Except for Higashiyodogawa, the highest concentrations of fluorotelomer alcohols (FTOHs) were for 8:2 FTOH (median 447 pg m(-3)) followed by 10:2 FTOH (56 pg m(-3)) and 6:2 FTOH (22 pg m(-3)). In contrast, 8:2 FTOAcryl (median 865 pg m(-3)) and 8:2 FTOH (1,864 pg m(-3)) were both major components in Higashiyodogawa. Compared to data published for North America and Europe, 8:2 FTOH levels are significantly higher in Keihan, suggesting a possible point source.
全氟辛酸（PFOA）是环境污染物，因其在环境中的长期持久性和生物累积性而引发特殊的公共卫生问题。氟调聚物醇具有挥发性，可能会进行远距离传输。在日本京阪地区的五个地点采集了空气样本：左京区、森宫以及东淀川区的三个地点。除东淀川区外，氟调聚物醇（FTOHs）的最高浓度是8:2 FTOH（中位数为447 pg m(-3)），其次是10:2 FTOH（56 pg m(-3)）和6:2 FTOH（22 pg m(-3)）。相比之下，8:2 FTOAcryl（中位数为865 pg m(-3)）和8:2 FTOH（1,864 pg m(-3)）都是东淀川区的主要成分。与北美和欧洲公布的数据相比，京阪地区的8:2 FTOH水平显著更高，这表明可能存在点源污染。
