Several halogenated flame retardants were detected in black kite, white stork and greater flamingo unborn eggs from Doñana Natural Space (Spain) collected in 1999, 2003, 2011 and 2013. The main components of Penta-BDE commercial mixture (BDE-47, -99 and -100) showed a decrease in the studied time interval, concurring with the ban of this mixture in the European Union (EU) in 2006. On the other hand, BDE-209, the main component of Deca-BDE mixture showed a clear trend in black kites but further monitoring is needed since its production ceased at the end of 2013. Besides, even if Dechlorane Plus (DP) was proposed by the EU as an alternative to BDE-209 no time trends were observed. Furthermore, total concentrations of PBDEs (classical FRs) are still higher than concentrations of hexabromocyclododecane (HBCD) and alternative FRs halogenated norbornenes (HNs), which are theoretically substitutes of the already banned PBDEs.

The toxicity of organophosphorus flame retardants (OPFRs) remains poorly understood, despite their widespread environmental presence and potential risks to human and ecological health. This study aimed to characterize the cardiovascular developmental toxicity of OPFRs using a high-throughput zebrafish screening model. Over thirty representative OPFRs, classified into three major groups-alkyl, aryl, and halogenated-were evaluated.

Environmental pollutants have been implicated in various detrimental health effects. However, the specific relationship between environmental pollutant exposure and the risk of cerebrovascular disease mortality remains uncertain. This study aimed to comprehensively explore the potential relationship between environmental pollutant exposure and risk of cerebrovascular disease mortality in the U.

The synthesis of highly efficient and environmentally friendly flame retardants through the synergistic interaction of boron, phosphorus and nitrogen is becoming a new research direction. In this study, N-DBSPA, a flame retardant with high flame retardancy, high thermal stability and high efficiency, was prepared by the reaction between pentaerythritol borate and amino trimethylene phosphate, and the limiting oxygen index (LOI) of the modified cotton fabric increased from 18 % to 44.7 % at a weight gain (WG) of 20.

Large-scale plastic wastes annually inevitably induce co-pollution of microplastics (MPs) and novel brominated flame retardants (NBFRs), while gaps remain concerning their effect on terrestrial function. We investigated the impact of polylactic acid (PLA) or polyethylene (PE) MPs after aging in soil-earthworm microcosms under decabromodiphenyl ethane (DBDPE) contamination. MPs altered the food (i.

The St. Lawrence Estuary (SLE) beluga () population in Canada is Endangered, and endocrine disrupting contaminants, such as polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), and other halogenated flame retardants, have been identified as a threat to the recovery of this population. Here, potential impacts of these contaminants on SLE beluga were evaluated by comparing skin transcriptome profiles and biological pathways between this population and a population less exposed to contaminants (Eastern Beaufort Sea) used as a reference.
