Abstract

Current understanding of potential anthropogenic/environmental drivers and ecotoxicological risks of emerging contaminants in the Amazon Basin, particularly organic flame retardants and plasticisers, is limited. We collected sediment samples from Amazonian Rivers near Manaus city/Amazonas State, Brazil, and measured concentrations of 39 organic flame retardants and plasticisers, namely: polybrominated diphenyl ethers (PBDEs), novel brominated flame retardants (NBFRs), dechlorane plus (DP), hexabromocyclododecane (HBCDD), organophosphate esters (OPEs), and polychlorinated biphenyls (PCBs). Concentrations of Σ 9 PBDEs, Σ 9 NBFRs, Σ 2 DPs, Σ 3 HBCDDs, Σ 7 OPEs, and Σ 9 PCBs ranged between
