I have to admit I,ve never paid much attention to air quality posts but the doctor told me yesterday that Udon currently has an air quality of pm2.5 which is very unhealthy as it means there are a lot of small particles floating about that can get into the nose,throat and lungs.
Areas where there is building work or where areas are being cleared are even worse.
A pm10 is much healthier as it means the particles are a lot larger and more difficult to get into the human system.
I never knew that.Most at risk are the elderly and the unfit.
