| Research Abstract |
Loads and risks of perfluorinated surfactants (PFSs) derived from non-point sources were evaluated. This study revealed that vehicle-derived particles contribute to PFSs in street dust, then in street runoff, and eventually enter into waters. Contributions of perfluorocarboxylates (PFCAs) from non-point sources to groundwater in Tokyo were estimated to be 16-46%. In an urban river, concentrations and loads of PFCAs were significantly higher during wet weather periods than during dry weather periods, and it was concerned that their risks through drinking water were high.
