Contractors have been ordered to halt construction work across the city, as these sites are known to be major contributors of PM10 — pollutants which measure less than 10 micrometres in diameter. In addition to road and building works, the state’s electric railway projects will also be affected by the order, said Pol Capt Phongsakon. The spokesman also said City Hall is working with the Bangkok Mass Transit Authority to check exhaust fumes from city buses to help reduce PM2.5 levels. According to city officials, PM2.5 levels ranged between 54 and 77 microgrammes per cubic metre (µg/m³) over the past 24 hours, higher than the Pollution Control Department’s “safe” threshold of 50µg/m³.
