Outline of Final Research Achievements

Environmentally persistent perfluoroalkyl substances (PFASs) have appeared as a new class of global pollutants. These compounds have recently emerged as a priority environmental pollutant due to its widespread finding in biota including both Arctic and Antarctic. However it is not well known about environmental fate of PFASs, especially in the Polar region.
In this study, the seawater and air samples from the Arctic and the Antarctic Ocean were collected and analyzed with newly developed ultra-trace level analysis. In comparison to PFAS concentrations measured eight years ago in the Arctic Ocean, the concentrations in this study were found to be almost same order and the same compositions. On the other hands, PFASs were mixed vertically and dramatically changed in short-term after strong wind event in the Arctic Ocean. It is first observation that PFAS concentrations were changed in the short-term, because of mixing event of seawater.
