Smog warning in Chiang Mai and Bangkok: Rising PM2.5 levels raise concerns

2025-01-07

Air pollution in Thailand has once again reached alarming levels, especially in Chiang Mai and Bangkok. The latest measurements show a sharp increase in PM2.5 particles, which has led to health warnings from authorities and medical experts.

Severe deterioration of air quality

According to Thailand's Pollution Control Department (PCD), the concentration of PM2.5 particles in Chiang Mai and Bangkok has risen above safe limits. Some areas have reached dangerous levels, increasing the risk of respiratory problems, especially for children, the elderly and people with underlying illnesses.

Dr. Anucha Phonprapai, an environmental scientist at Chulalongkorn University, warns that the smog can cause long-term health problems. "We are seeing an increase in respiratory diseases and allergies, and long-term exposure can lead to heart and lung diseases."

Causes behind the smog

The deteriorating air quality is due to:

  • Traffic emissions from big cities
  • Forest fires and agricultural burning
  • Industrial pollution
  • Weather conditions that prevent the spread of particles

Authorities are trying to reduce pollution through restrictions on burning and calls to reduce car traffic, but problems remain.

Health risks and recommendations

Health authorities recommend:

  • Use of PM2.5 filter masks outdoors
  • Restriction of outdoor activities
  • Closed windows and doors to reduce exposure
  • Use of air purifiers

Thailand's Ministry of Public Health suggests distance learning and homework during extreme smog.

Measures and future solutions

The government plans to:

  • Stricter emission regulations
  • Support for public transport and electric vehicles
  • Cooperation with neighboring countries to reduce forest fires

Environmental experts are calling for long-term solutions. Residents are advised to follow official air quality updates.
