Antarctic Research Bases: local source of polybrominated Diphenil Ether (PBDE) flame retardants

However, some emerging pollutants exhibiting characteristics of persistence comparable to POPs should also be considered. Hale et al. (2006) highlighted the presence of polybrominated diphenyl ether (PBDE) in sediment next to McMurdo station.

These compounds are used as flame retardant and are present in many modern polymer-containing products, e.g., home/office furnishings and electronics. BDE-209, the major constituent in commercial deca- PBDE products, was the dominant congener in sludge and dust, as well as aquatic sediments collected near the McMurdo wastewater outfall. Pattern and BDE-209 sediment concentration, in conjunction with its limited environmental mobility, suggested inputs from local sources.
