“…In contrast, HBCDD diastereoisomer profiles showed a predominance of a-HBCDD in birds' tissues/eggs (Guerra et al, 2012), fish (Xia et al, 2011;Meng et al, 2012), mollusks (Zhu et al, 2012), ringed seals (Vorkamp et al, 2011) and other biota, suggesting the impact of environmental processes on the change of diastereoisomer contribution.…”

“…A higher fraction of (À)-a-HBCD was also reported for peregrine falcons from Sweden (Janák et al, 2008) and Canada (Guerra et al, 2012). Selective uptake and/or degradation of either the enantiomer may result in the enrichment of (À)-a-HBCD (Guerra et al, 2012).…”

“…Selective uptake and/or degradation of either the enantiomer may result in the enrichment of (À)-a-HBCD (Guerra et al, 2012). An in vitro experiment using rat liver microsomes revealed a longer half-life for (À)-a-HBCD than (+)-a-HBCD, supporting the aforementioned hypothesis (Esslinger et al, 2011).…”

“…DBDPE was detected in two out of seven pools showing concentrations at 9.3 and 44 ng/g w.w. Guerra et al (2012) studied the occurrence of DBDPE in eggs from peregrine falcon (Falco peregrinus) from Canada and Spain. In a total of 25 eggs DBDPE was detected in just one egg at 8.2 ng/g fat (LOD = 1.1 ng/g fat, LOQ = 5.2 ng/g fat).…”

Scientific Opinion on Emerging and Novel Brominated Flame Retardants (BFRs) in Food

EFSA was asked to deliver a scientific opinion on brominated flame retardants (BFRs) other than PBDEs, PBBs, HBCDDs, TBBPA and brominated phenols and their derivatives. The BFRs that are the subject of the current opinion, were classified in groups termed "emerging" and "novel" BFRs. Information on 17 emerging and 10 novel BFRs was collected. The information varied widely for these BFRs. There is a lack of experimental data on physico-chemical characteristics, stability/reactivity and current use and production volume of all the emerging and novel BFRs. Due to the very limited information on occurrence, exposure and toxicity, the CONTAM Panel could not perform a risk characterisation for any of the BFRs considered. Instead, an attempt was made to identify those BFRs that could be a potential health concern and should be considered first for future investigations. For this purpose the Panel first evaluated the available experimental data on occurrence in food, behaviour in the environment and toxicity. Secondly, a modelling exercise was performed focussing on the potential of the emerging and novel BFRs for persistence in the environment and for their possible bioaccumulation potential. There is convincing evidence that tris(2,3-dibromopropyl) phosphate (TDBPP) and dibromoneopentyl glycol (DBNPG) are genotoxic and carcinogenic, warranting further surveillance of their occurrence in the environment and in food. Based on the limited experimental data on environmental behaviour, 1,2-bis(2,4,6-tribromophenoxy)ethane (BTBPE) and hexabromobenzene (HBB) were identified as compounds that could raise a concern for bioaccumulation. For the modelling exercise, the CONTAM Panel selected two environmental characteristics, overall persistence and potential for bioaccumulation, as being most relevant to provide insight into the possibility that emerging or novel BFRs The less well known and less studied BFRs, subject of the current opinion, were grouped into two classes, referred to herein as "emerging" and "novel" BFRs. Emerging BFRs are defined as chemicals which are applied as flame retardants and that have been identified in any environmental compartment, in wildlife, in food or in humans. It should be noted that the definition for the emerging BFRs, used in this opinion, does not imply that there is evidence for an increasing trend in the concentration of these BFRs in the environment, in food or in human samples. Novel BFRs are defined as chemicals applied as flame retardants, with confirmed presence in materials and/or goods in concentrations above 0.1 %, but not identified in environmental samples, wildlife, food or humans. In total, information on 27 BFRs, of which 17 were identified as "emerging" and 10 as "novel", was collected by the CONTAM Panel, and it was noted that the available information varied widely for the various individual BFRs.In general, there is a lack of experimental data on physico-chemical characteristics and stability/reactivity for all the emerging and novel BFRs. This sometimes hampered ...
