Proximity of public schools to major highways and industrial facilities, and students’ school performance and health hazards

Abstract

Children with consistent exposure to air pollution have increased asthma, chronic respiratory problems, and neurobehavioral dysfunction. However, many schools are located in close proximity to highways and industrial facilities which are key sources of air pollution to children. The goal of this study is to explore the association between the proximity from schools to highways and industrial facilities, and children’s school performance and health hazards. We measured the distances from 3,660 Michigan public schools to highways and industrial facilities, and linked these to the Michigan Educational Assessment Program test performance rate and the National Air Toxics Assessment’s respiratory and neurological hazards. We found that schools located closer to highways and industrial facilities had higher risks of respiratory and neurological diseases than those located farther away. We also found that schools located closer to major highways had a higher percentage of students failing to meet the state standards than the latter after controlling for the location of schools, student expenditure, school size, student–teacher ratio, and free lunch enrollment. In addition, a larger percentage of black, Hispanic, or economically disadvantaged children attended schools nearest to pollution emissions than white students.
