Description

Perfluorinated compounds (PFCs) are a class of persistent environmental contaminants widely applied in commercial and industrial applications to render products water and oil repellant. These compounds are characterized by their hydrophobic chain made up of carbon fluorine bonds and a polar end consisting of a carboxylic acid or sulfonic acid functional group. Recently, these synthetic compounds were detected at concentrations ranging from 1.5 to 41 ng L-1 in surface waters collected from Puget Sound in Washington State and in Clayoquot and Barkeley Sounds in British Columbia. However, there has been limited data for these emerging contaminants of concern in biota from the Puget Sound. This study will present preliminary measurements of PFC concentrations from Pacific blue mussel (Mytillus trosollus) samples collected as part of the Mussel Watch Pilot Expansion Project in 2012 led by the Washington State Department of Fish and Wildlife. PFCs will be analyzed in samples from mussels transplanted in various shoreline areas in order to evaluate the extent of contamination in Puget Sound’s nearshore biota for these persistent and potentially toxic contaminants.
