There’s some good news for sushi lovers. A new report finds that over an 8-year period, mercury levels in Gulf of Maine tuna declined 2 percent a year — a decline that parallels reductions in mercury pollution from Midwest coal-fired power plants.

Two years ago, Dr. Nicholas Fisher, a professor of marine sciences at Stony Brook University in New York, had a bit of luck — he found out that a colleague had established a collection of 1,300 western Atlantic bluefin taken from the Gulf of Maine between 2004 and 2012.
