Indoor Air in School
Good-quality indoor air in schools contributes to providing a healthy environment for students, teachers and staff. While we know a lot about some indoor hazards, such as asbestos, radon, tobacco smoke and pollution from outdoor sources, greater attention has recently been given by the scientific community to the health relevance of other indoor air pollutants (see, for example, the guidance published by the World Health Organization). These biological and chemical pollutants may be released directly into the air from indoor sources that are part of the school environment, including the people inside the building, since behavioural factors such as smoking, overcrowding or using allergenic fragrances for personal care can be sources of chemical pollutants. Indoor air quality is of particular concern when it comes to children, whose physiological and behavioural characteristics make them especially vulnerable to environmental contaminants and to the impacts of climate change.
