High levels of molecular chlorine found in Arctic atmosphere
Previous Arctic studies have documented high levels of oxidized mercury in Barrow and other polar regions. The major source of elemental mercury in the Arctic regions is coal-burning plants around the world. In the spring in Barrow, ozone and elemental mercury are often depleted from the atmosphere when halogens—chlorine and bromine—are released into the air from melting sea ice.
"Molecular chlorine is so reactive that it's going to have a very strong influence on atmospheric chemistry," Huey said.

"There is definite climate change happening in the Arctic," Huey said. "That's changing the nature of the ice, changing the volume of the ice, changing the surface area and changing the chemistry of the ice."
