The Department of Pollution Control recommends that people in red zone areas avoid spending long periods outdoors, especially vulnerable groups such as young children, the elderly, and people with respiratory illnesses. They should also wear face masks to protect themselves from small particles and seek medical attention if they experience any unusual symptoms.
The main causes of PM2.5 are the burning of fossil fuels from vehicles, industrial plants, and agricultural activities. The current weather conditions in Bangkok and its vicinity are characterised by still air, which is causing the accumulation of small particles, resulting in critical air quality.
