Original Title:
Προσδιορισμός βρωμιωμένων επιβραδυντικών ανάφλεξης (BFRs) σε ευρωπαϊκά και ασιατικά πουλιά
Translated title:
Monitoring of contaminants of BFRs in European and Asian raptors
Summary:
Brominated Flame Retardants are compounds, widely used as additives to
textiles, construction materials and electrical devices, to prevent fire
ignition and spreading. Even though most of them are currently listed as
Persistent Organic Pollutants (POPs) under the 2011 Stockholm Convention,
they seem to be still present in the environment. Monitoring of these
compounds in birds of prey can provide us with information regarding their
accumulation and transfer to higher organisms of the food chain. In this
study we included the analysis of seven Polybrominated Diphenyl Ethers
(PBDEs) and also the total concentration of Hexabromocyclododecane (HBCD)
in samples of peregrine falcon from the Netherlands. In addition, samples
from birds of prey from Sicily and Pakistan were also analyzed for
comparison. Liver, muscle and egg samples of peregrine falcon were
provided by the Dutch Peregrine Falcon Group. Samples from Sicily and
Pakistan were provided from a previous work done in the same laboratory by
Krystalenia Karaberopoulou two years ago, as part of her master internship
thesis. The samples were analyzed by Gas chromatography- mass spectrometry
(GC-MS) with pulsed splitless injection. Internal standards, procedural
blanks and internal reference material (IRM) with a recovery standard were
included for quality assurance. Performance characteristics monitored,
included precision accuracy, limit of detection (LOD) and limit of
quantification (LOQ). Overall, PBDEs and sum HBCD were present in all
samples of birds of prey. BDE 153 was the main contaminant in the samples
from the Netherlands (8.7-260 ng/g ww), while BDE 99 dominated in samples
from Sicily (0.01-21 ng/g ww) and Pakistan (0.49-27.7 ng/g ww). Sum HBCD
was also found in all samples, with the highest values in samples taken
from the Netherlands, while the highest concentration of sum BDEs was
found in peregrine falcons from the Netherlands.
