Air quality in North still ‘critical’
Air pollution across the upper North remains at critical levels with authorities monitoring almost 400 active hotspots in Chiang Mai alone on Sunday. The air quality did not improve on Monday morning, with IQAir recording “very unhealthy” air quality and hazardous, ultra-fine PM2.5 dust levels at 170.1 microgrammes per cubic metre (μg/m³) at 10.30am in the so-called “Rose of the North”.
