The Pollution Control Department has warned the level of hazardous dust particles will remain high in greater Bangkok on Monday and Tuesday, trapped by stagnant air, and called for strict enforcement of dust and smoke regulations.
Without wind, fine particulate matter with a diameter of less than 2.5 micrometres (PM2.5) exceeded the safe level of 50 microgrammes per cubic metre of air in many areas of greater Bangkok on Monday morning.
The PM2.5 measured 60-81mcg on the streets and 49-79mcg away from main roads.
Apart from many areas of Bangkok, hazardous dust levels were also reported in Nakhon Pathom, Pathum Thani, Samut Prakan, Samut Sakhon and Nonthaburi provinces.
The Pollution Control Department asked authorities to be strict in ordering vehicles emitting black smoke off the roads and to prevent people lighting fires outdoors, and asked motorists to reduce their use of private vehicles.
The Bangkok Metropolitan Administration planned to discuss rainmaking to settle the dust and alleviate the weather conditions.
