Bangkokians have been warned the unhealthy air pollution that has shrouded the Thai capital for four consecutive days was unlikely to improve on Monday, as city authorities ordered controls on outdoor burning and traffic police clamped down on black exhaust-spewing vehicles.
The Pollution Control Department (PCD) urged people to stay indoors and when they did go out, to wear a KN95 or N95-rated face mask which are designed to block against fine airborne particulate matter. Normal face masks were not effective enough.
PM2.5 Levels Far Exceeding Safety Limit In Some Areas
Air quality readings in at least 20 locations showed particulates measuring 2.5 microns or less – known as PM2.5 and which can potentially cause serious health problems by infiltrating the respiratory system – exceeding Thailand’s set safety level of 50 micrograms per cubic metre.
On Sunday morning, the worst affected area was Tambon Pak Nam in Muang Samut Prakan with a PM2.5 reading of 93 micrograms per cubic metre. Rama II Road in the same district was recorded at 90 micrograms, Soi Lat Phrao 95 in Wang Thong Lang district at 73 micrograms and Paholyothin Road in Chatuchak district at 72 micrograms.
The PCD said humidity and lack of wind had contributed to the dangerous air pollution levels plaguing Bangkok and its vicinity. The department’s director-general Pralong Damrongthai said the PM2.5 level was unsafe in Phayathai, Din Daeng, Lat Phrao, Min Buri, Bang Khun Thien and Rama II Road.
The PCD was working with city authorities, traffic police, the Department of Land Transport and government ministries to combat the unhealthy air pollution. Pralong said vehicles belching black exhaust fumes were being tagged with stickers and ordered off the roads.
Bangkok governor Aswin Kwanmuang warned against or to reduce time spent on outdoor activities in risk areas.
