Starting in May 2009, BioDiversity Research Institute (BRI) expanded upon the 2007 and 2008 broad-based contaminant study on Maine birds, measuring both historical and emerging chemicals. Out of the 23 species studied in the first two years, we determined that osprey (Pandion haliaetus) foraging in Casco Bay required additional study in 2009. We selected osprey because they act as bioidicators of the marine habitat. The compounds we analyzed in ten eggs from Casco Bay were mercury (results pending), polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), perfluorinated compounds (PFCs), and organochlorine pesticides (OCs). The results in this report also include the six osprey eggs we analyzed in 2007.
