Air Pollution Near California Schools
More than 245 million pounds of industrial air pollution were emitted near California schools in 1995, according to the most recent available state and federal data analyzed by Environmental Working Group (EWG). Fully half of the state's schoolchildren, in public and private schools, attended class within a mile of reported air emissions of chemicals known to cause cancer, reproductive damage, developmental disabilities or respiratory illness.
