Indoor air pollution continues to be a threat to the health of children around the world. A new study warned that the air in some U.K. schools is more toxic than outdoor air, an article in British Telecommunications stated.

Researchers from the University of Cambridge (Cambridge) and the University College London (UCL) conducted the study on indoor air pollution. They were commissioned by the Mayor of London, who has recently launched a campaign to protect the city’s children from toxic air.

The study covered five primary schools and a nursery in London. It analyzed the PM2.5 and PM10 scale particulate matter inside the schools. It showed that the particulate matter (PM) in the classrooms exceed the limits set by the World Health Organization (WHO).

In particular, the indoor PM10 pollution levels were higher than the outdoor levels whenever the classrooms were occupied. During both heated and unheated seasons, the average PM10 level in the classrooms exceeded 20 milligrams per cubic meter (mg/m3). Meanwhile, the mean PM2.5 level was more than 10 mg/m3.

Based on these findings, the study said that the children in these classrooms are exposed to concentrations of particular matter that exceed the 2010 guidelines established by the WHO. Indeed, the PM levels in most of the rooms are higher than what is considered to be safe on a daily
