Hexabromocyclododecane in gull egg samples: results published, data searchable
Data of a retrospective monitoring study on HBCD in herring gull eggs are published and can now be searched.
Hexabromocyclododecane (HBCD) is among the most used brominated flame retardants throughout the world. HBCD is relatively persistent in the environment and has been detected in biotic and abiotic compartments with increasing concentrations. For this reason the German Environmental Specimen Bank investigated the temporal trend of HBCD in herring gull eggs from the Baltic Sea and the North Sea coast. The time series covers the years 1988 to 2008.
The diastereomers α-, β- and γ-HBCD including the respective pair of enatiomers were analysed. Contrary to technical HBCD which consists mainly of γ-HBCD only α-HBCD was detected in gull eggs. These data are now searchable.
