Lead and mercury levels in livers of bald eagles recovered in New England

Metadata Updated: December 11, 2017

Between 2001 and 2012, we collected liver samples from 127 bald eagles carcasses prior to their transfer to the National Eagle Repository. We analyzed liver tissue for lead (Pb) and for mercury (Hg), which is another regionally important contaminant. The vast majority of the bald eagles were recovered in Maine, but a few were recovered in Massachusetts (5), Connecticut (2) and New Hampshire (1). In 127 New England bald eagle livers, 14% had Pb concentrations indicative of poisoning (> 30 ppm dry weight). The average Hg level in New England bald eagle livers was 13.49 ppm dry weight, which was higher than average levels recorded in bald eagles from British Columbia (11.8 ppm), several Great Lake states (7.97 ppm), and Alaska (7.10 ppm).
