Studies confirm presence, severity of pollution in national parks
Date:6/23/2010

CORVALLIS, Ore. Toxic contamination from pesticides, the burning of fossil fuels, agriculture, industrial operations and other sources are a continuing concern in national parks of the West, two new studies confirm.

In research performed by an international group of scientists over several years, pollution was found in all eight of the national parks and preserves that were studied, in terrain ranging from the Arctic to southern California. Most of it was caused by regional agriculture or industry, but some had traveled thousands of miles from distant sources in Asia and elsewhere.

The two recent reports, both published in Environmental Science and Technology, reinforce previous research that has identified such problems, scientists say, and better quantify the extent of the concerns.

"As scientists we're getting more used to these pollution problems," said Staci Simonich, an associate professor of environmental and molecular toxicology at Oregon State University, and lead investigator on both studies. "Pesticide pollution is now so routine that we've had to look at museum specimens to find baseline data that existed prior to pesticide use.

"But it still seems surprising that such remote and supposedly pristine areas are not all that pristine," she said. "You never really get used to that. And we're now nailing down just where the real problems are and what is causing them."

The biggest concern, Simonich said, appears to be pesticides, which can bioaccumulate in the ecosystem and food web, and were most often linked to regional agricultural activities. Of the areas studied, the largest problems with pesticides were found in Sequoia, Rocky Mountain and Glacier National Park.

This research did not attempt to evaluate the full scope of environmental impacts, but scientists did observe some disturbing evidence of male fish at some high-elevation locations becoming "feminized" and developing eggs a proble
