Air pollution from industrial sources near Michigan public schools jeopardizes children's health and academic success, according to a new study from University of Michigan researchers. The researchers found that schools located in areas with the state's highest industrial air pollution levels had the lowest attendance rates—an indicator of poor health—as well as the highest proportions of students who failed to meet state educational testing standards. The researchers examined the distribution of all 3,660 public elementary, middle, junior high and high schools in the state and found that 62.5 percent of them were located in places with high levels of air pollution from industrial sources.
