“…Based on the detected PBDE congeners, in addition to the PBDE congener percentage in each commercial PBDE mixture, the identified congeners in Sparus aurata could result from the use of the commercial Penta-BDE, Octa-BDE, and Deca-BDE formulations (El Megdiche et al 2017). The possible source of PBDEs might be deposition (or leaching) from high temperature and photo degradation of commercial products of deca-BDEs such as in textiles in upholstery, electronic circuit boards, mattresses, and TVs used (Kofi et al 2018). It could possibly come from the deposition from products containing penta-BDE formulation as additives such as textiles and polyurethane foams; pyrolytic/thermally degraded residual deposits from deca-BDE formulations such as in textiles, electronic circuit boards, mattresses, and TVs used (Kofi et al 2018); and finally from leaching/residual deposits from penta/octa-mix BDE formulations such as in polyurethane foams and acrylonitrile-butadiene-styrene (ABS raisins) used in plastics for some household electric devices such as computers and housing appliances.…”

This study aimed to the examination of the levels and effects of organobromine compounds (polybrominated diphenyl ethers: PBDEs and methoxylated brominated diphenyl ethers: MeO-PBDEs), in Sparus aurata native to the Lagoon of Bizerte. For that, different biomarkers of exposure (somatic indices, superoxide dismutase, and catalase activities) and effect (malondialdehyde level, histopathologic alterations, and DNA damage) as well as pollutant levels were measured in specimens collected from this impacted ecosystem and the Mediterranean Sea as a reference site. Bizerte Lagoon PBDE fish levels were higher than the Mediterranean Sea, whereas MeO-PBDEs were higher in the reference site. Fish from Bizerte Lagoon presented a higher hepatosomatic index, lower catalase and superoxide dismutase activity, higher level of malondialdehyde, and higher percentage of DNA tail in comparison to fish from the reference area. The histological study of the liver indicated substantial lesions in fish from the polluted site. The results showed strong positive correlations between the concentrations of the PBDE or MeO-PBDE and the MDA and DNA tail % levels and negative correlations for the activities of enzymes of SOD and CAT. Consequently, these findings could suggest a potential link between exposure to these pollutants and the observed biomarker responses in the Bizerte Lagoon seabream. Taken together, these results highlight the importance of biomarker selection and the selected sentinel fish species as useful tools for biomonitoring of aquatic pollution.
