Air quality in Bangkok improves and getting better next week

The air quality in Bangkok has improved since Saturday after the amount of particulate of less than PM2.5 had steadily reduced to 40-50 microgram/cubic metre, according to the Department of Pollution Control.

The department said that air quality readings from the five monitoring stations in Bang Na, Wang Thong Lang, Pathumwan, Thon Buri and Ratchathevi districts as of 8 am on Sunday show that the amount of particulate in the atmosphere ranges from 40-50 microgram/cm which is less than the 50 microgram/cm standard compared to above 50 microgram/cm. measured during February 14-16.

Meanwhile, the Thai Meteorological Department said that air quality in Bangkok was expected to improve further the coming week due to rainfalls.

The Weatherman predicted cloudy sky during February 19-23, with the possibility of rains covering 10-30 percent of the areas in Bangkok and this will further reduce the amount of particulate in the atmosphere.

Bangkok on Sunday was blanketed with fog, with heavy fog in some areas and with low temperatures ranging from 24-26 degrees Celsius and high temperatures ranging from 34-37 degrees Celsius.

Meanwhile, Mr Surasee Kittimonthon, director-general of Royal Rainmaking and Agricultural Aviation Department, urged motorists in Bangkok to reduce their use of private cars and to turn to public transport in order to help reduce air pollution.

He explained that the department had deployed seven aircrafts for cloud-seeding operation in the sky above Bangkok, but the operation was not possible due to heavy air traffic above Bangkok.

Also, he noted that the low relative humidity of the atmosphere above Bangkok � measured at 30 percent at the altitude of 20,000 feet � was still below the 60 percent required for cloud seeding operation.
