Quarter of UK pupils attend schools where air pollution is over WHO limit

Estimated 3.4m children learn in unhealthy environment, says charity behind research

Millions of British children attend schools where air pollution is worse than the World Health Organization limit, campaigners have said.

An analysis found that more than a quarter of schools, from nurseries to sixth-form colleges, were in locations with high levels of small particle pollution. This means an estimated 3.4 million children are learning in an unhealthy environment, said Global Action Plan (Gap), the charity behind the research that was released on Clean Air Day on Thursday.
