Novel brominated flame retardants and dechloranes in three fish species from the St. Lawrence River, Canada

Novel brominated flame retardants and dechloranes in three fish species from the St. Lawrence River, Canada Restrictions in the utilization of polybrominated diphenyl ether (PBDE) mixtures have led to the increased usage of alternative flame retardant additives in a wide range of commercial applications. The present study examined the occurrence of established and emerging flame retardants (EFRs) in fish from a densely-populated urbanized sector of the St. Lawrence River (Montreal, Quebec, Canada). Thirty-eight PBDE congeners and sixteen EFRs were determined in fish belonging to three predatory species (yellow perch, northern pike, and muskellunge). The bioavailability of these EFRs in human-impacted aquatic ecosystems warrants further environmental assessment and toxicity testing.
