"Significant declines in perennial Arctic sea ice over the past decade may be intensifying a chemical reaction that leads to deposits of toxic
mercury, a NASA-led study showed on Thursday.
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."
