EPA Finds Manganese Threat at 2 Schools

Regulators have found high levels of neurotoxic manganese in the air outside two schools in Ohio and West Virginia, the latest results of the U.S. Environmental Protection Agency's efforts to check for chemicals outside schools across the nation.
Government scientists have determined that long-term exposure to manganese can cause mental disabilities and emotional problems, especially in kids.
The preliminary results, to be released today, found average manganese levels at least 70% higher than what the EPA considers safe for long-term exposure outside Warren Elementary School in Marietta, Ohio, and Neale Elementary School in Vienna, W.Va. The schools are about 10 miles from each other.
