Tests conducted at 500 sites show particle pollution exceeded health guidelines on 6% of school days
Keeping the classroom window closed is not the answer to reduce the amount of pollution coming into schools, a recent study has found.
A project called SAMHE (Schools’ Air quality Monitoring for Health and Education) operated air pollution monitors in nearly 500 classrooms for an academic year and found that days with high outdoor pollution led to higher pollution inside the classrooms.
The Imperial College London researchers found that 6% of school days had outdoor particle pollution above the World Health Organization’s daily guidelines and these days contributed 17% of the annual classroom pollution.

Six percent of school days had outdoor particle pollution above the World Health Organisation’s daily guidelines, but these days contributed 17 percent of the annual classroom pollution.
