Occurrence of Polybrominated Diphenyl Ethers, Polychlorinated Biphenyls, and Phthalates in Freshwater Fish From the Orge River (Ile-de France)

Abstract

Polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs), and phthalates were investigated from July 2009 to April 2010 in three fish species from the Orge river, which flows in a densely populated area of Ile-de-France. In two Cyprinidae (roach and chub) and one Percidae (perch), muscle contents in increasing order ranged as follows: 12-18 ng g(-1) dw for PBDEs (Σtri-hepta), 120-170 ng g(-1) dw for PCBs (Σ7), and 2,250-5,125 ng g(-1) dw for phthalates (Σ7). No variation was observed between contaminant contents and lipid levels. No biomagnification was found according to the trophic level for PBDEs and PCBs, whereas for phthalates the highest contents were found in perch. Seasonal variations were observed with the lowest PBDE and PCB contents occurring in July after spawning in roach and perch (p < 0.001). PBDE content followed a decreasing trend-gonad > liver > muscle-whatever the period. For PCBs, gonad and liver contents remained greater than that of muscle (p < 0.05). Our results indicate a preferential accumulation of halogenated compounds in gonad and liver outside the reproduction period. Bioaccumulation factors for PCBs in muscle were significantly correlated to their chlorination degree in perch (p < 0.01) and roach (p < 0.01). In roach, that correlation slope was by decreasing importance order as follows: gonad > liver > muscle. The biota-sediment accumulation factors varied from 0.1 to 29.2, from 1.6 to 4.8, and from 1 to 123.5 for PBDEs, PCBs, and phthalates, respectively. These results contribute to document the use of freshwater fish as bioindicators of river quality.

Persistent Organic Pollutants in sediment and fish in the River Thames Catchment (UK)

“…It is assumed that POPs in water, fish and sediment are at equilibrium and the BSAFs do not substantially change with varying environmental factors. For the 6 BDEs and the ICES 7 PCBs, the BSAF factors were a bit lower than those reported for the same fish species from the Orge River (France) (Teil et al, 2012). The BSAF factors for BDE 28 and BDE 47 were much higher than those for other congeners, which is consistent with the findings of Teil et al (2012) and Sellström et al (1998).…”

Bioavailability and bioaccumulation of sediment‐bound polychlorinated biphenyls to carp

“…The concentrations were much higher than those reported for sites located in the same region but unexposed to direct industrial contamination such as dam ponds (0.8 ± 0.2 ng/g dry wt, 1.3 ± 1.2 ng/g dry wt, and 0.4 ± 0.1 ng/g dry wt for PCBs 138, 153, and 180, respectively ). The concentrations were higher than values observed in rivers located in densely populated areas such as in the Orge River (France), a tributary of the Seine River (16.6 ng/g dry wt, 19.2 ng/g dry wt, and 14.1 ng/g dry wt for PCBs 138, 153, and 180, respectively ). The main congener measured in the collected sediment was PCB 153, which is consistent with the literature .…”

Polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans and polybrominated diphenyl ethers in sediments and fish species from the Murchison Bay of Lake Victoria, Uganda

“…The PBDE levels were lower than the data reported in fish from Ghana (Asante et al, 2013), South Africa (Wepener et al, 2012), China (Hu et al, 2010;Xiang et al, 2007), Spain (Labandeira et al, 2007;Lacorte et al, 2006), France (Teil et al, 2012) and the United States Streets et al, 2006) (Table 4). BDE 47 the most predominant congener in the sediments was also abundant in fish (Fig.…”
