Chiang Mai sprays water to increase air humidity to reduce air pollution
Chiang Mai sprayed water to increase air humidity to reduce air pollution after the PM10 values had been found to exceed the safety standard level.
Many sectors in Chiang Mai jointly constructed firebreaks to reduce the risk of forest fires and increase moisture in the air to reduce dust and haze while the PM10 values have exceeded the safety standard level for three consecutive days.
