Where did the Great Salt Lake's methylmercury go?

April 25 (UPI) -- Several years ago, mercury levels in Great Salt Lake waterfowl were high enough to warrant a human consumption advisory for ducks -- a rarity. Levels of toxic methylmercury were also high.

Today, mercury levels in wetlands and local wildlife remain elevated, but the methylmercury is mostly gone.

As explained in a study, researchers aren't exactly sure where the methylmercury went or what's to blame for elevated mercury levels in local wetlands.

The Great Salt Lake is dissected by a railway. The line divides the lake into two parts. The north arm of the lake has no natural inflow, and exchange of water between the north and south arms is limited to a pair of culverts built into the causeway.
