Strict burning ban starts in Chiang Mai

A BAN on all kinds of burning for 60 days kicked off in Chiang Mai today (Feb. 20) where the particulate matter (PM) is 86 micrograms per cubic meter, Thai  News Agency said.

Chiang Mai Governor Pawin Chamniprasart has offered a cash reward of 5,000 baht to informers who help the authorities arrest violators while also ordering all units to strictly enforce the ban which ends of April 20.

According to, particle pollution, also called particulate matter or PM, is a mixture of solids and liquid droplets floating in the air. Some particles are released directly from a specific source, while others form in complicated chemical reactions in the atmosphere.

Particles come in a wide range of sizes. Particles less than or equal to 10 micrometers in diameter are so small that they can get into the lungs, potentially causing serious health problems. Ten micrometers is less than the width of a single human hair.

People with heart or lung diseases, older adults and children are most likely to be affected by particle pollution exposure. However, even if you are healthy, you may feel temporary symptoms if you are exposed to high levels of particle pollution. Numerous scientific studies connect particle pollution exposure to a variety of health issues, including:

  • irritation of the eyes, nose and throat
  • coughing, chest tightness and shortness of breath
  • reduced lung function
  • irregular heartbeat
  • asthma attacks
  • heart attacks
  • premature death in people with heart or lung disease
