Occurrence of priority and emerging organic compounds in fishes from the Rhone River (France)

Résumé

The main objective of this study was to collect new data on the occurrence and levels of priority and emerging organic compounds in freshwater fishes sampled in the Rhone River. The 34 studied contaminants included alkylphenols (AP), bisphenol A (BPA), polybromodiphenylethers (PBDE), perfluorinated compounds (PFC), hexabromocyclododecanes (HBCD), hexachloro-benzene (HCB) and hexachloro-butadiene (HCBD). About 50 fish samples (individual specimens or pooled fishes) were collected from 3 sites located upstream and downstream of the Lyon metropolitan area in the Rhone River (France). Four species were caught at each site, namely: the barbel (Barbus barbus), the common bream (Abramis brama), the white bream (Blicca bjoerkna) and the chub (Squalius cephalus). Some contaminants were quantified in all the 32 fish samples analysed: 4-nonylphenol, Α-HBCD, the 6 PBDE congeners (28, 47, 99, 100, 153, 154), perfluorooctanesulfonate (PFOS) and perfluorodecanoic acid. And 23 of the 32 samples had concentration of PFOS above the Environmental Quality Standards (up to 6 times higher the EQS); and all the 32 samples had concentrations of PBDE above the EQS (up to 4000 times higher, with the sum of 6 PBDE varying from 4.5 to 182 ng/g dw). Clearly, the interest to consider PFOS and HBCD as new priority substances is confirmed. In contrast, the pertinence of a priority status for HCBD, which was never quantified in our study, might have to be reconsidered in the future.
