The Pollution Control Department (PCD) warned vulnerable Bangkok people, such as those with heart and respiratory diseases, a warning on Monday to avoid outdoor activities during this period as the PM2.5 level had reached 89 micrograms per cubic metre in recent days.
At 68.83 micrograms, the PM2.5 daily average reported for Bangkok’s Wang Thonglang District was beyond the safe limits of both the PCD, which is at 50 micrograms and the World Health Organisation, at 25 micrograms.
Monday’s PM2.5 daily average in some other provinces also reached beyond safe standards, including in Samut Sakhon (109.2 micrograms), Ratchaburi (92.91 micrograms), Tak (92.43 micrograms), Kanchanaburi (75.4 micrograms) and Samut Prakan (69.69 micrograms).
The China-based air quality monitoring website, http://aqicn.org, reported Bangkok’s PM2.5 level as of Monday afternoon had reached a critical level at 162 micrograms. The highest level recorded over the past five days was 174 micrograms.
PCD director-general Sunee Piyapanpong said that the rising air pollution in many provinces, and Bangkok, was the result of the week’s cold and moist weather causing particulate matter in the air to accumulate to a dangerous level.
