Description
Recently, perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA), which are concerned as a new class of persistent organic pollutants, have been found to be widely distributed in many living organisms including human. We measured concentrations of PFOS and PFOA in 38 tap water samples collected from several areas in Japan, Thailand, Malaysia, Sweden, Vietnam, China and Canada; and conducted systematic surveys of PFOS and PFOA at surrounding surface water sites. A solid phase extraction coupled with liquid chromatography/mass spectrometry (LC-MS) was used for analysis. Main conclusions were as follows:(1) Most of collected tap water samples were contaminated with PFOS and PFOA with the concentrations ranged from the limit of quantification levels to 13 ng/L for PFOS and 109 ng/L for PFOA.(2) The level of tap water concentrations was generally related to the level of surrounding surface water concentrations whether the source of tap water was the surface water or not.(3) In Japan, tap water PFOA concentrations were relatively high in Biwako-Yodo River area (Otsu, Kyoto, Osaka), mostly due to its contamination of Lake Biwa and Yodo River.
