The interest in reducing environmental lead exposure is evident with the recent revision by the U.S. Environmental Protection Agency (EPA) for the nation’s Air Quality Standards, which were lowered from 1.5 to 0.15 ug of lead per cubic meter of air. “With these stronger standards, a new generation of Americans is protected from harmful lead emissions, especially children,” said EPA Administrator Stephen L.
