BANGKOK (NNT) – Overall air quality remained at unhealthy levels in northern Thailand, particularly in the provinces of Phrae and Phayao, as of Tuesday morning (Feb 18). In Bangkok and neighboring provinces, the concentration of dust particles rose but was within safety limits.

The Pollution Control Department advised today that levels of particulate matter of 2.5 microns or less (PM2.5) in the air in greater Bangkok measured between 12 and 31 micrograms per cubic meter. The PM2.5 levels increased at almost all air-monitoring stations, but they remained below the danger level, set at 50 micrograms per cubic meter. People can still engage in outdoor activities at this time.
