Cell broadcast system to provide real-time updates as Thailand’s PM2.5 season nears

A nationwide alert system for PM2.5 fine dust pollution, including real-time updates through the cell broadcast system, is in the works as air quality in Bangkok is worsening to the “orange” level with the onset of the cool season.
The Pollution Control Department (PCD) and related agencies are working to expedite development of the system, in collaboration with the telecom operator Advanced Info Service (AIS).
The goal is to ensure the public receives accurate, timely information about air quality directly on their mobile phones, according to the Ministry of Natural Resources and Environment.
The PCD will act as the lead agency responsible for monitoring and reporting PM2.5 levels nationwide. The data will be transmitted to the Department of Disaster Prevention and Mitigation, which will distribute alerts via the cell broadcast system to residents in affected areas without requiring users to install additional applications.
The alerts will include three key components: the current situation and severity of PM2.5 concentrations, forecasts and trends in the affected areas, and health and safety recommendations for the public to reduce exposure and mitigate health risks.
Air quality in Bangkok began to worsen this week, with PM2.5 levels reaching the orange level in three districts, indicating negative health impacts.
Fine dust pollution in Bangkok has many causes, notably vehicle emissions and open burning, which includes agricultural burning, waste burning and forest fires.
