Report: Mercury levels dropping in some Mass. fish

BOSTON (AP) — A new Massachusetts Department of Environmental Protection report is drawing a connection between a drop in mercury levels in fish and efforts to reduce mercury emissions from incinerators, power plants and other sources.

The report said that in a mercury "hotspot" near several solid waste incinerators, levels of the toxic heavy metal in largemouth bass and yellow perch dropped by more than 40 percent after local mercury emissions were cut by 98 percent.

The report said there's been a 13 percent mercury reduction statewide in largemouth bass and a 19 percent reduction in yellow perch between 1999 and 2011.

Officials say the drop in mercury levels in fish is tied to state efforts to reduce sources of mercury pollution, eliminate unnecessary mercury uses and improve recycling.

Fish from many Massachusetts lakes and ponds still remain unsafe to eat
