Schools: Better learning in healthy air | Umweltbundesamt

Some of the causes of contaminated air in schools are excessively high levels of carbon dioxide as a result of sealed windows or inadequate airing. Too much humidity can cause mould. Add to that emissions of hazardous substances from building materials and cleaning agents. Particulate matter impairs pupils’ health not only on their way to school but also in the classroom itself- regardless whether it originates from outside or within the school.

The effects of poor air quality on both pupils and teachers are mainly headache, fatigue, and inability to concentrate. ”Healthy air plays a considerable part in successful learning. Because education is important the authorities should take all measures necessary to guarantee clean air in schools. Regular airing by fits and starts during every short break can help a lot”, continued Troge.

Troge also made an appeal not to allow urgently needed remediation work in schools to take second place to other supposedly more important tasks. ”Many school buildings have technical defects that are unacceptable on health grounds”, said Troge. It is true that a number of school buildings have been redeveloped in recent years, as it was suspected there was asbestos, polychlorinated biphenyls or other hazardous substances, but it is now time to face new challenges--  issues such as particulate matter, poor acoustics or persistent mould.
