DIASTEREOISOMER-SPECIFIC ACCUMULATION OF HBCD IN CZECH FRESHWATER FISH

Popis výsledku v původním jazyce

Hexabromocyclododecane (HBCD) is a representative of a group of flame retardants (BFR), mainly used as additive in polystyrene foams and for coatings of fabrics for furniture. HBCD is the second most used BFR in Europe (tetrabromobisphenol A is the dominating BFR). Technical 1,2,5,6,9,10-HBCD is a mixture of three diastereoisomeric pairs of enantiomers as racemic mixtures, ?-, ß- and ?-HBCD. The commercial mixtures consist mainly of the ?-HBCD diastereoisomer (75 - 89 %), while ?- and ß-HBCD are presentin a considerably lower amounts. The dissimilarities in the structure of the diastereoisomers cause the differences in biological and toxicological properties, e.g. different solubility in water, which may result in distinctive rates of biological uptake and biotransformation. The predominant isomer usually found in fish was ?-HBCD. [1]. Once released into the environment and because of their generally low solubility in water, they can adsorb onto the sediment particles. The resistance
