ENVIRONMENTAL FATE OF PERFLUOROALKYL SUBSTANCES IN OPEN OCEAN ENVIRONMENT

Perfluoroalkyl substances (PFASs) such as perfluorooctanesulfonate (PFOS) and perfluorooctanoic acid (PFOA) are global environmental contaminants. However, it is not well known about environmental fate of PFASs, especially for global transportation. One of the reason is PFASs has unique physicochemical properties. They have high water solubilities despite the low reactivity of C-F bond, which also imparts high stability in the environment. In this study, we investigated concentrations of PFASs in open ocean environment (seawater and atmosphere). Here we report a global scale monitoring survey of PFASs conducted during 2002 – 2013
