Health risks stack up for students near industrial plants

ADDYSTON, Ohio — The growl of air-monitoring equipment has replaced the chatter of children at Meredith Hitchens Elementary School in this Cincinnati suburb along the Ohio River.  School district officials pulled all students from Hitchens three years ago, after air samples outside the building showed high levels of chemicals coming from the plastics plant across the street. The levels were so dangerous that the Ohio EPA concluded the risk of getting cancer there was 50 times higher than what the state considers acceptable.
