PCBs in the eggs of Eurasian Kestrels indicate exposure to local pollution

By Giacomo Dell'Omo, David Costantini, Julian Wright, Stefania Casagrande and Richard F. Shore


Fail-to-hatch kestrel (Falco tinnunculus) eggs collected at\ud the end of the 1999 and 2005 breeding seasons from nest\ud boxes in and around the city of Rome, Italy, were analyzed\ud by gas chromatography with electron capture detection for\ud their PCB content and for the presence of DDT derivatives\ud and other organochlorines. Among the various PCBs,\ud congeners 153 and 180 were detected in all the eggs and\ud showed the highest concentrations. Eggs collected from\ud the same nest from a polluted location in Rome during 2\ud different years showed similar type and number of PCB\ud congeners. These data and the fact that eggs from\ud another nest near a sulphate mine had, atypically, lowchlorinated\ud congeners support the conclusion that eggs of\ud this species, whose adults in the Mediterranean and\ud continental Europe perform only short or no migration\ud movements, might be indicative of local pollution. When\ud multiple eggs in the same clutch were analyzed, the PCBs\ud were similar in type but their concentration decreased\ud within clutch, likely in parallel to the laying order
