The Pollution Control Department has warned people with respiratory and heart problems to wear face masks to protect themselves when going out-door due to poor air quality in Bangkok.
The department said the cold weather has worsened the air quality, with the amount of particulate matter smaller than 2.5 micron, or PM2.5, in some areas has exceeded the safety level of 50 microgramme/cubic metre.
Areas with high level of PM2.5 are Rama IV road in Pathum Wan district (54 microgramme/cubic metre); Intharapitak road in Thon Buri district (65); and Lat Phrao road in Wang Thong Lang district (53).
The department has pleaded with all sectors of the society in Bangkok to contain activities which may give rise to the increase of particulate matter in the atmosphere, such as construction work, burning of materials and car emissions.
The Weatherman, meanwhile, predicted further drop in mercury by 1-3 degrees Celsius to 15-19 degrees Celsius tomorrow (Feb 7).
