Aquatic rest stops may pose potential hazards for migratory waterfowl

Migratory waterfowl around the world travel hundreds to thousands of miles annually, stopping at lakes, ponds and marshes to refuel and breed. Some of these aquatic rest stops may be at sites polluted by remnants of radioactive waste from nuclear production or accidents, exposing the birds to contamination that they take with them. This poses a potential risk to humans if the waterfowl enter the food chain.
