GRANTS PASS, Ore. -- Scientists looking for fish tainted by mercury found them in every fish and every river they sampled across the West, suggesting that industrial pollution generated around the world is likely responsible for at least some of it.
The survey of 2,707 fish randomly collected from 626 rivers in 12 states represents the biggest regional sampling yet of mercury in fish in the West, said Spencer A. Peterson, senior research ecologist EPA's National Health and Environmental Effects Research Laboratory in Corvallis.
The findings by scientists from the EPA and Oregon State University were reported in this month's issue of the journal Environmental Science & Technology and came out of an EPA survey of various environmental factors in rivers conducted between 2000 and 2004.
Though the survey found some fish with elevated mercury levels, suggesting a local source such as an old mercury mine, most levels were low, in line with canned tuna found in grocery stores, said Alan T. Herlihy, associate research professor in the OSU Department of Fisheries and Wildlife.
