  • Title: Partitioning behaviour of perfluorinated alkyl contaminants between water, sediment and fish in the Orge River (nearby Paris, France).
    Author: Labadie P, Chevreuil M.
    Journal: Environ Pollut; 2011 Feb; 159(2):391-7. PubMed ID: 21112680.
    Abstract:
    This paper reports on the partitioning behaviour of 15 perfluorinated compounds (PFCs), including C(4)-C(10) sulfonates and C(5)-C(14) carboxylic acids, between water, sediment and fish (European chub, Leuciscus cephalus) in the Orge River (nearby Paris). Total PFC levels were 73.0 ± 3.0 ng L(-1) in water and 8.4 ± 0.5 ng g(-1) in sediment. They were in the range 43.1-4997.2 ng g(-1) in fish, in which PFC tissue distribution followed the order plasma > liver > gills > gonads > muscle. Sediment-water distribution coefficients (logK(d)) and bioaccumulation factors (logBAF) were in the range 0.8-4.3 and 0.9-6.7, respectively. Both distribution coefficients positively correlated with perfluoroalkyl chain length. Field-based biota-sediment accumulation factors (BSAFs) are also reported, for the first time for PFCs other than perfluorooctane sulfonate. logBSAF ranged between -1.3 and 1.5 and was negatively correlated with the perfluoroalkyl chain length in the case of carboxylic acids.
