Air quality in and around Bangkok improved today (Sunday) with no areas of Bangkok currently affected by excessive levels of PM2.5 dust particles.
The Pollution Control Department described air quality today as very good to moderate, with levels of PM2.5 particulate matter ranging from 24-46 microns, below the 50-micron standard.
However, the department said that the quantity of fine dust particles will increase slightly tomorrow, but the general air quality will still be within 50-micron standard.
On Saturday, the Bangkok Metropolitan Administration, in cooperation with relevant agencies, organized a big cleanup on Rama III road in Bang Khun Thian district and on the Vibhavadi Rangsit highway today.
Today, small aircraft from Bangkok Aviation School continued water spraying operations for a second day.
Meanwhile, about 16,000 runners took part in a charity marathon run this morning from Ratchamangala stadium in Hua Mark through central Bangkok to the finish line at the Democracy monument on Rajdamnoen road.
Prior to the night time start of the marathon, the race organizers closely monitored updates on the pollution situation before it was declared safe for the race to begin.
About 50 medical staff were deployed to provide help in case any competitors developed health issues during the run.
Additionally, water cannons were deployed at four locations along the route to spray water into the air in the event that dust levels increased.
