Time Trends of Mercury in Feathers of West Greenland Birds of Prey During 1851-2003
Temporal trends of mercury (Hg) in West Greenland gyrfalcons, peregrine falcons, and white-tailed eagles were determined over 150 years from 1851 to 2003. Hg was measured in the fifth primary feather. Results showed that Hg increased in the order gyrfalcon (lowest)<peregrine falcon (intermediate)...
