Distributions and bioconcentration characteristics of perfluorinated compounds in environmental samples collected from the west coast of Korea

► Waterborne concentrations of PFCs reflected land use and local activities. ► Concentrations of PFCs in soils and sediments were less than those in biota. ► Composition of PFCs cross target aquatic organisms reflected species-specific accumulation. ► Field-based BCFs for PFCs significantly varied among species and compounds. ► Compound- and organ-specific bioconcentration of PFCs in fishes was observed.
