Several novel brominated flame retardants (NBFRs), such decabromodiphenyl ethane (DBDPE) and bis(2,4,6-tribromophenoxy) ethane (BTBPE), have been developed as replacements for PBDEs. NBFRs are used in various industrial and consumer products, which leads to their ubiquitous occurrence in the environment. This article reviews occurrence and fate of a select group of NBFRs in the environment, as well as their human exposure and toxicity. Occurrence of NBFRs in both abiotic, including air, water, dust, soil, sediment and sludge, and biotic matrices, including bird, fish, and human serum, have been documented.

  • Polybrominated Diphenyl Ethers (Pbdes)
    DRAFT FOR ÉBAUCHE POUR PUBLIC COMMENTS COMMENTAIRES DU PUBLIC Canadian Environmental Protection Act, 1999 Environmental Screening Assessment Report on Polybrominated Diphenyl Ethers (PBDEs) February 2004 Environment Canada where x + y = 1 to 10 Figure 1. PBDE structure Introduction The Canadian Environmental Protection Act, 1999 (CEPA 1999) requires the Minister of the Environment and the Minister of Health to conduct screening assessments of substances that meet the categorization criteria set out in the Act and Regulations to determine, in an expeditious manner, whether substances present or may present a risk to the environment or to human health. Based on the results of a screening assessment, the Ministers can propose taking no further action with respect to the substance, adding the substance to the Priority Substances List (PSL) for further assessment, or recommending that the substance be added to the List of Toxic Substances in Schedule 1 and, where applicable, the implementation of virtual elimination. A screening assessment involves an analysis of a substance using conservative assumptions to determine whether the substance is “toxic” or capable of becoming “toxic” as defined in CEPA 1999. This environmental screening assessment examines various supporting information and develops conclusions based on a weight of evidence approach as required under Section 76.1 of CEPA 1999. The screening assessment does not present an exhaustive review of all available data; rather, it presents the most critical studies and lines of evidence supporting the conclusions. One line of evidence includes consideration of risk quotients to identify potential for ecological effects. However, other concerns that affect current or potential risk, such as persistence, bioaccumulation, chemical transformation and trends in ambient concentrations, are also examined in this report.

In effect, flame retardants are now ubiquitous in our environment, and as a result, our exposures are chronic and difficult to circumvent – at work and at home. Human exposures can differ considerably as factors such as geographic location, socio-economic standing, and ethnicity are all factors influencing the intensity of exposures. Polychlorinated biphenyls (PCBs), the first set of flame retardants, are considered persistent organic pollutants under the Stockholm Convention. Prohibition of the import, manufacture, and sale (for re-use) and release to the environment of PCBs in Canada, was followed by the introduction of another set of “safer” flame retardants – polybrominated diphenyl ethers (PBDEs), now designated “CEPA toxic.” With the proposed listing of decaBDE to Annex A of the Stockholm Convention at the upcoming Convention of Parties 8 (COP8) in April 2017, with specific exemptions2, the process of substitution has been initiated. As of December 23, 2016, the manufacture, use, sale, offer for sale and import of decaBDE and products that contain decaBDE will 1 Canada Gazette, Part 1.

  • Polybrominated Diphenyl Ethers (Pbdes)
    Biomonitoring | Polybrominated Diphenyl Ethers (PBDEs) Polybrominated Diphenyl Ethers (PBDEs) Polybrominated diphenyl ethers (PBDEs) are a group of brominated flame retardant chemicals that have been incorporated into a variety of manufactured products, including foam cushioning used in furniture and plastics used in televisions and computers. Flame retardants are intended to slow the rate of ignition and fire growth, allowing more time for people to escape from a fire or extinguish it. All PBDEs have a common structure of a diphenyl ether molecule, which may have from 1–10 bromine atoms attached; each particular PBDE variant is referred to as a congener. In theory, there could be as many as 209 PBDE congeners, but a much smaller number of congeners are commonly found in the commercial PBDE mixtures and in measurements of PBDEs in humans and the environment. Three commercial PBDE mixtures have been used in manufactured products since the 1960s and 1970s, when these chemicals came into use,1 with each mixture made up of congeners with varying degrees of bromination. The commercial pentabromodiphenyl ether (pentaBDE) and octabromodiphenyl ether (octaBDE) mixtures have not been manufactured or imported in the United States since 2004. The pentaBDE mixture, made up primarily of four- and five- bromine congeners, was used almost entirely in flexible polyurethane foam in furniture, mattresses, carpet padding, and automobile seats; and the octaBDE mixture, made up primarily of seven- and eight-bromine congeners, was used in acrylonitrile-butadiene-styrene (ABS) plastic for certain electric and electronic devices. A third product, the commercial decabromodiphenyl ether (decaBDE) mixture, is still manufactured and used in the United States.
