Mercury-tainted fish found widely in U.S. streams
• ReutersScientists have detected mercury contamination in every one of hundreds of fish sampled from 291 freshwater streams.
More than a quarter of those fish contained concentrations of mercury exceeding levels set by the Environmental Protection Agency for the protection of people who eat average amounts of fish, the U.S. Geological Survey report said.
More than two-thirds exceeded the EPA-set level of concern for fish-eating mammals.
