Spatial distribution and loading amounts of particle sorbed and dissolved perfluorinated compounds in the basin of Tokyo Bay

► Thirty types of PFCs in suspended solid collected from Tokyo Bay basin were analyzed. ► Relatively high levels of PFCs in SS were observed in urbanized areas. ► More than 90% of the total PFCs reached Tokyo Bay in the dissolved phase. ► However, 40-84% of the long chain PFCAs were transported as particle sorbed PFCs.
