Detecting poison in white-tailed sea eagles

Save raptors in Germany


Especially white-tailed sea eagles, red kites and buzzards are affected by illegal poisonings. Due to the high costs, a systematic examination of the carcasses dissected is not possible, so that analyses by laboratories can only be carried out in selected individual cases.

This campaign wants to establish a laboratory dedicated to detect poison in raptors and in the enviroment. For this a gas chromatograph with mass spectrometer (GC-MS/MS triple quadrupole) should be purchased to strengthen toxicology work of  of Dr Oliver Krone, an international renown expert for raptor science.  With the help of the planned laboratory Krone will be able to analyse biological matrices of wildlife for commonly used toxins. A triple quadrupole mass spectrometer is a tandem mass spectrometer consisting of two quadrupole mass analysers connected in series. This achieves low detection limits while at the same time being easy to operate. Mainly carbofuran, mephinvos and parathion have been detected in the birds of prey examined by Dr. Krone.   A “GC-MS/MS” would enable Dr Krone to systematically examine carcasses and other samples collected in the field for toxins.   In the period from 2005 to 2017, a total of 393 proven poisonings or cases with strong suspicion of poisoning were detected in Germany. At least 1,020 birds of prey and owls, i.e. about 59 % of all recorded persecution victims, were killed.
