This paper reports the results of a pilot study of polybrominated flame retardents in household dust collected for a small sample of households in Plymouth. It finds significant levels of pentaBDE especially in bedrooms. The most likely cause is the continued use of pentaBDE within polyurethane foam in mattresses and other bedroom furniture, in spite of the ban by the European Court of Justice in 2004. Further work is called for in order to examine whether this reflects the widespread continued use of mattresses and furniture bought before 2004. A larger sample size is envisaged, including more detail on the nature and age of furniture and upholstery in households.
The indoor environment is where human beings spend most of their time, whether at home or at work, resulting in a high level of exposure to dust. Dust is a heterogeneous assortment of particles derived from differing sources which include trace metals and chemical congeners. In 2004 Polybrominated diphenyl ether (PBDEs) pentaBDE and octaBDE were banned by the European court of Justice. Although decaBDE is still used in the North American market in residential upholstered furniture and mattresses. (Chao, et. al. 2014) Polybrominated diphenyl ether (PBDEs) have been extensively used as flame retardants for highly flammable consumer goods throughout homes, cars and workplaces. (Webster, et. al. 2015) PBDEs are a class of brominated flame retardants that have been found in humans and wildlife
