Riverdale, NJ, December 28, 2021 (GLOBE NEWSWIRE) – A 2019 study by researchers in the Department of Atmospheric Sciences at the University of Utah found a statistically significant correlation between air pollution and absences school.

More than 135 million Americans, or more than 40% of the population, are exposed to dangerous levels of air pollution in their communities on a daily basis. Exposure to hazardous air and the health threats associated with it disproportionately affect people of color and low-income families, according to the National Lung Association.
Schools in low-income communities are often built on the cheapest plots of land available, placing them next to high-traffic roads and other areas at high risk of excessive pollution levels. Since school funding is allocated based on property taxes in the school zone, schools serving low-income families do not have sufficient resources to upgrade their HVAC systems to accommodate filtration solutions. high efficiency air that would protect the students.

Utah study finds link between particles and school absences

A 2019 study by researchers in the Department of Atmospheric Sciences at the University of Utah found a statistically significant correlation between air pollution and school absences. Even minor increases in air PM2.5 levels in the Salt Lake City, Utah school district were linked to an increase in school absences the next day.

While this correlation does not prove a cause-and-effect relationship, the finding aligns with other research on the topic conducted before and since the University of Utah study.

What is particulate matter?

Often abbreviated as PM1, PM2.5, or PM10, these microscopic airborne particles are known to cause damage to human health as well as industrial equipment and processes. Particles can be anything.

PM are classified by measuring their diameter in microns. Different classifications of particulate matter affect different parts of the body in different ways and require different filtration solutions. A micron, or micrometer, is a unit of measurement equal to one millionth of a meter, or one thousandth of a millimeter. For reference, there are 25,400 microns in an inch.

PM10 are inhalable particles with a diameter of ten microns or less. PM2.5 are inhalable particles with a diameter of 2.5 microns or less. This type of particulate matter is often referred to as fine particulate matter. PM1 are inhalable particles with a diameter of 1 micron or less.

To get an idea of ​​the size of fine particles:

  • A strand of human hair measures on average 70 microns in diameter
  • A sheet of copy paper is typically 100 microns thick
  • A pollen grain is usually between 10 and 40 microns in diameter

Benefits of using high efficiency air filters in schools

Why is the air quality in schools so bad?

While location is responsible for some of the air pollutants that affect children in schools, school buildings themselves are major sources of indoor air pollution. Data from the 2014 National Center for Education Statistics survey revealed that the average age of main school buildings was 55 years old. This means that the middle school was built between the late 1950s and early 1960s.

Old buildings are prone to radon and asbestos fumes, both of which are extreme health threats. Additionally, the architecture of this period was designed to keep the outside air out – thick insulation, tight seals around windows and doors, and vapor barriers. But it also seals indoor pollutants inside.

Indoor air pollution comes from a variety of sources, including:

  • Cleaning chemicals and air fresheners.
  • Printers, copiers or other equipment that uses large amounts of ink.
  • Furniture, especially inexpensive furniture, emits formaldehyde and other harmful chemicals.
  • Students, teachers, staff and visitors, who bring allergens and particles from outside sources onto their clothes, and lose tens of thousands of skin cells every minute, which contributes to dust accumulation .
  • Excessive humidity.
  • Molds, mildew and other pathogens and microbes.

Studies by the EPA have also shown that areas where many people congregate, such as school cafeterias and gyms, are five times more polluted than other areas.

The implications of air pollution for education

The impact of air pollution on education as a whole goes beyond a few missed school days at the individual level. In many states, state aid to schools is allocated on the basis of attendance records. Excessive absences due to air pollution can seriously affect the education of children in general due to reduced funds, even if they did not miss school due to a health related illness. pollution.

In addition to the physical health threats that polluted air poses to developing lungs as well as to the lungs of adults, polluted air is linked to decreased productivity, decreased cognitive abilities, blood pressure swings. mood and irritability. These factors affect students and teachers. Overall, polluted air greatly affects the education of American children.
