Air Pollution Resolution Centre forecasts that in Bangkok and its vicinities the poor air quality will start affecting their health over the next one day but outlook for Apr. 11-17 is for PM2.5 level to edge down to the benchmark after Apr. 11 because of open weather conditions with no stagnant air lingering.

People in the 17 provinces of the Northern region will also start feeling an impact of poor air quality over the next one day. Over the next one week, they should beware of April 16-17 as there will be several hot spots which could raise PM2.5 level.

According to IQAir, a Swiss air quality technology company that operates AirVisual which is a real-time air quality information platform, at 9 a.m. today Bangkok had the fourth worst air quality in the world after Pakistan, India and Beijing.
