IN THE face of persistent air pollution in the North, Chiang Mai University (CMU) has decided to issue warnings for locals to think twice before using the outdoor zone of its stadium.

If PM2.5 dust particles exceeds 35.5 micrograms per cubic metre of air within 24 hours, CMU will put up a sign warning children, the elderly, pregnant women, people with respiratory, heart and brain arteries problems, and athletes to avoid going outdoors. 

If PM2.5 goes beyond 55.5mcg per cubic metre of air, the warning will cover everyone. The World Health Organisation (WHO) has described PM2.5, or dust particles that are 2.5 microns or less in diameter, as carcinogenic. Prolonged exposure can cause several health problems and in severe cases, even death.
