How big a problem is poor Indoor Air Quality in schools?

Nearly 56 million people, approximately 20 percent of the U.S. population, spend their days inside elementary and secondary schools. In 1999, the National Center for Education Statistics of the U.S. Department of Education reported that approximately 25 percent of public schools described unsatisfactory ventilation, while 20 percent of schools told of unsatisfactory IAQ. IAQ problems can cause discomfort and contribute to short- and long-term health problems for students and staff.
