Abstract:
This paper reports on the partitioning behaviour of 15 perfluorinated compounds (PFCs), including C₄–C₁₀ sulfonates and C₅–C₁₄ carboxylic acids, between water, sediment and fish (European chub, Leuciscus cephalus) in the Orge River (nearby Paris). Total PFC levels were 73.0±3.0ngL⁻¹ in water and 8.4±0.5ngg⁻¹ in sediment. They were in the range 43.1–4997.2ngg⁻¹ in fish, in which PFC tissue distribution followed the order plasma>liver>gills>gonads>muscle. Sediment–water distribution coefficients (logKd) 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.
