The Hidden Dangers of Poor Air Quality in Schools

Viruses and Solvents

Indoor air quality has emerged as one of the most critical issues in schools, influencing not only the health and productivity of students, but also affecting airborne disease transmission. In 2011, a study published in Environmental International¹ highlighted that elevated levels of indoor air pollutants increase the risk of health problems among schoolchildren. Markers, pens, and glues release volatile chemicals, including alcohols and other solvents, which can linger in the air for a long time. This leads to an increased risk of developing respiratory diseases such as asthma and allergies, negatively affecting learning outcomes.

Similarly, construction materials can release gases for a long time after a school or university has been built. While mixtures like paint cure within just hours, some types of flooring and insulation continue to emit fumes for years after they were installed, leading to a noxious atmosphere in some newer buildings.

Carbon Dioxide

Another overlooked indoor air pollutant is CO₂—an odourless, colourless gas which can cause headaches, drowsiness, restlessness, and even absenteeism in high concentrations. Since human exhalation is the primary source of CO₂ indoors, measuring its concentration provides a straightforward way to assess air quality. This is significant not only because elevated CO₂ levels can lead to fatigue but also because it may indicate conditions that facilitate the transmission of airborne illnesses, including COVID-19 and the common cold.

A Cost-Effective Answer

One of the best first steps staff or parents can take to determine if a school’s air quality is putting anyone’s health at risk is learning how to use a carbon dioxide data logger. It’s a portable, intuitive device that records CO₂ concentration over time. It can be placed inside a classroom or worn in a low-profile belt pack during the school day. With the ability to wirelessly connect to a laptop or desktop computer, it will clearly demonstrate how levels change throughout the day.

Ensuring proper air quality in schools is essential for fostering a safe learning environment and promoting academic success. Education is expensive—often adding up to hundreds of thousands of dollars per child—and recognizing the importance of a healthy learning environment is imperative. Prioritizing air quality ensures that every student has the opportunity to achieve their full potential. It’s a small decision that reflects a commitment to the health and success of future generations.
