Toxic Metals in the air outside School complex

Testing for toxics at schools sparks questions, lawsuits

NATRONA HEIGHTS, Pa. — On crisp fall mornings in the Allegheny River valley, the fog that hangs over Highlands High School usually burns off by the first bell. What remains in the air is the question.

Almost a year after tests by USA TODAY found significant levels of two potentially toxic metals in the air outside the school, local health officials expanded their own monitoring efforts here.

Highlands, flanked by two metals plants, is among scores of schools where regulators — local, state or federal — are monitoring outdoor air for toxic chemicals, many that pose unique dangers to kids.
