The air quality in most areas of Bangkok metropolitan was moderate on Wednesday morning, the Air Quality Information Centre of the Bangkok Metropolitan Administration (BMA) said.



The centre reported the average PM2.5 levels throughout the city on Wednesday at 32.8 micrograms per cubic metre (mcg), slightly under the country’s standard of 37.5 mcg over a three-hour average (5am to 7am), but worse from yesterday morning’s average of 26 mcg.
