CONTAMINATION OF PERFLUORINATED COMPOUNDS IN THE RIVER WATER OF HYOGO PREF., JAPAN
One Liter of surface water was sampled at monitoring points. In 2007, 54 river water, 14 sea water, and 15 sewage works effluent samples were collected. In 2008, 40 river water samples were collected. The analysis was carried out using LC/MS/MS. The investigation was carried out to grasp the perfluorooctanoate (PFOA) and Perfluorooctane sulfonate (PFOS) contamination of environmental waters in Hyogo Prefecture, Japan. PFOA concentrations and detected ratios (number of detected samples / all samples) were higher than PFOS. In 2008, the congener analysis was carried out using LC/MS/MS. PFOA was detected as the predominant congener in a lot of sampling points. In the Tatsumi Bridge, congener distribution was characteristic. The concentration of PFHxA was about 20 times higher than PFOA. Meanwhile, the PFOA concentration was decreasing. It is thought that the convert to product with a short carbon chain is reflected in these rivers. In coastal area, PFOA were detected and the concentrations were higher at closed-off section of the Osaka bay observed than other area. Therefore, it was thought that the influence from the PFOA source appeared through the river. In the sewage works effluent, PFOA and PFOS were detected of all samples, and the concentration level is higher than environmental water samples.
