Mercury pollution increases 45x in Arctic bird over last 130 years

No change in diet, massive increase in mercury. Check out the Wikipedia article on mercury poisoning for why this is not a good thing.

Biologists at the University of Saskatchewan, Canada, say the ivory gull (Pagophila eburnea) acts like a “mercury barometer”, sounding alarm bells for contamination of Arctic animals with mercury pollution.

”We’re concerned because the mercury’s going up but their diet hasn’t changed over the 130 years we’ve studied,” lead researcher, Dr Alex Bond, told BBC News.

”This is a genuine increase - it’s gone up 45 times, which is twice the average for an animal species in the Arctic.”
