; and (3) to support the Nation’s schools to advance environmental justice. 3. Findings Congress finds the following: (1) Substantial research demonstrates that air pollution negatively impacts health and cognition. (2) More than 1 in 5 public schools in the United States are located within a mile of a toxic release site. Nearly 1 in 11 public schools, serving 4,400,000 students, are less than 500 feet from a major road. (3) According to a 2017 report, 4 percent of schools serving predominantly White students are next to major roads, while 15 percent of schools serving largely students of color are next to major roads. (4) Indoor levels of air pollutants can be 2 to 5 times higher, and sometimes 100 times higher, than outdoor levels. In 2014, nearly half of schools in the United States reported having problems related to indoor air quality. (5) Schools in poor repair may have additional air quality problems, including lead, asbestos, dust, and radon contamination. (6) Poor indoor air quality increases the risk of severe asthma attacks and allergic reactions. Asthma is the leading cause of missed school days in the United States. (7) High-performance air filters can decrease indoor particulate matter by 90 percent. (8) Research demonstrates the potential for school air filters to improve student learning. In 2016, commercial air filters were installed in every classroom, office, and common area of 18 public schools in Los Angeles. Controlling for student demographics, mathematics test scores at these schools improved dramatically, nearly matching the impact of reducing class sizes by a third, and gains persisted the following the year. 4.
