SALT LAKE CITY (AP) -- A new study says elevated mercury levels might be harming brine shrimp in the Great Salt Lake and birds that eat them.

The U.S. Geological Survey says it's still unclear how much lasting damage the mercury is causing. That will be the focus of another study expected to be completed early next year.

The new study says the amount of mercury found in grebes increases during periods when they dine heavily on the lake's brine shrimp.

Nathan Darnall, an ecologist with U.S. Fish and Wildlife Service, says mercury can cause neurological problems for birds and affect their ability to fight off diseases.
