Outline of Final Research Achievements

We conducted a study to elucidate the transfer kinetics of perfluorooctanesulfonate (PFOS) to a marine sandworm species via the gut. We established an individual-expousre system, chemical analytical method of PFOS in sandworm and food pellet samples, and the method to spike PFOS to food pellets. We then conducted a trnsfer experiment and kinetically anlyzed the results. We estimated the gut absoprtion efficiency at about 100% and the depuration halflife at 91 days. The depuration was statistically insignificant. The depuration halflife was longer than the results of earlier studies using other aquatic organisms and of a previous experiment of the respiratory uptake of this species. Thus, further investigations, also regarding other perfluoro/polyfluoro-alkyl acid compounds, on the underlying mechanisms of this difference is needed.
