Air quality worsens but data lacking in Northeast areas
Air pollution from particulate matter smaller than 2.5 microns (PM2.5) continues to ravage the North and Northeast but no accurate measurements are available, as many provinces do not have PM2.5 monitoring stations.
As seasonal haze intensifies in the North from the accumulation of fine particulate matter in the air, a PM2.5 monitoring device in Khon Kaen yesterday indicated that air pollution was also occurring in the Northeast. However, the extent across the region is unknown as only Khon Kaen has a monitoring station.
