By Dan Whitcomb – The study found that thick, perennial Arctic sea ice was being replaced by a thinner and saltier ice that releases bromine into the air when it interacts with sunlight and cold, said Son Nghiem, a NASA researcher at the Jet Propulsion Laboratory in Pasadena.
That in turn triggers a chemical reaction called a “bromine explosion” that turns gaseous mercury in the atmosphere into a toxic pollutant that falls on snow, land and ice and can accumulate in fish, said Nghiem, lead author of the study. more> http://tinyurl.com/7eb48sq
