Classroom air quality may be causing respiratory problems
Classrooms have come a long way. 40 years ago, the ambient air was good and all classrooms had open doors and windows. But as the education landscape evolves, so do the challenges associated with the health and safety of students and educators. Back then, our health concern was limited to the problem of chalk dust suspended in the air. Inhaling chalk dust can potentially be harmful to your health, especially if you are exposed to large amounts over a long period. The dust produced by chalk is made up of small particles of calcium carbonate, which can irritate the respiratory system and cause breathing problems in some people.
