Bangkok Tests Dry Ice to Combat Severe Smog Crisis

The city is experimenting with aerial dry ice dispersal to reduce hazardous PM2.5 pollution levels affecting millions.

Bangkok is experiencing dangerously high levels of PM2.5 air pollution, prompting health warnings for residents to stay indoors and wear masks outside.
City authorities are using a novel approach involving the dispersal of -70°C dry ice from aircraft to create ventilation channels in the atmosphere.
Initial test flights, supported by a donation of 300 tons of dry ice, showed a significant reduction in fine particulate matter levels.
Long-term implementation would require substantial investment in aircraft and dry ice production facilities to sustain the effort.
Primary pollution sources include vehicle emissions from congested roads, widespread use of fossil fuels, and emissions from tens of thousands of factories in the region.
