New research published in The Condor: Ornithological Applications, has shown that shorebirds breeding in Alaska are being exposed to alarming levels of mercury, putting their entire population at risk. Shorebirds travel to Alaska for their breeding season in the spring, before making the long trek down to Central and South America for the fall and winter.
Due to atmospheric circulation and other factors at play in the Northern hemisphere, high amounts of mercury deposits have been found to accumulate in the Arctic, raising concerns for the breeding populations of these birds.According to Phys.org, mercury exposure has been linked to reduced reproductive success and other adverse health reactions in shorebirds.Even more alarming, the type of mercury present in the aquatic environments that shorebirds commonly forage in, is, for the most part, methylmercury, the chemical element's most dangerous form.
