Spatial diastereomer patterns of hexabromocyclododecane (HBCD) in a Norwegian fjord

Review of hexabromocyclododecane (HBCD) with a focus on legislation and recent publications concerning toxicokinetics and -dynamics

“…Its percentage usually increases in the food chain (Li et al, 2011) and sometimes ends up being around 100% in top predators like gannets and gulls (Janak et al, 2008;Leslie et al, 2011;Esslinger et al, 2011a;Haukas et al, 2009). However, trophic magnification factors (TMF) vary considerably.…”

Diastereoisomer- and species-specific distribution of hexabromocyclododecane (HBCD) in fish and marine invertebrates

“…The mobility of the organisms, the effects of the contaminated sediments, the organisms' proximity to pollution sources, and the organisms' enzymatic capacity could cause the low levels of HBCD concentration in crustacea. According to Haukås et al [32], the HBCD in shore crabs may be related to habitat and feeding patterns because shore crabs are predators and scavengers. Overall, our results showed no conspicuous differences in terms of HBCD exposure between vagile and sedentary marine organisms (p > 0.05).…”

Advances in the study of current-use non-PBDE brominated flame retardants and dechlorane plus in the environment and humans

“…Concentrations of HBCD ranged from 0.88 to 4.8 pg/g dry wt and HBCD chiral signatures are racemic in sediments [25]. Haukås et al [47] reported concentrations and spatial distribution of -, -, and -HBCD in a contaminated Norwegian fjord. The results indicated -HBCD gradient with decreasing concentrations at increasing distance from the point source in sediments.…”
