The fine dust in northern provinces is eroding air quality, posing a threat to respiratory health and prompting the authorities to beef up measures to prevent forest and outdoor fires.

The Natural Resource and Environment minister is scheduled to discuss outdoor-fire prevention and air pollution with eight northern provincial governors at Chiang Mai City Hall tomorrow.

The Pollution Control Department's air-quality stations reported that dust particles of 10 microns in Chiang Mai, Lampang and other northern provinces yesterday at 9am were above 120 micrograms per square metre (mpsm) and the Air Quality Index (AQI) score was higher than the safety standard of 100.

Central Chiang Mai's air-quality station at Yupparaj School measured 10-micron dust at 149.6 mpsm and an AQI score of 113, while Lampang reported 272.5mpsm and an AQI score of 166. Chiang Rai had 181mpsm, Nan 141.3mpsm, and Phayao 145.6mpsm.

A 15-per-cent increase of respiratory patients was reported at Lampang Central Hospital in the past week, hospital director Songwuth Sabthavisin said.

Chiang Mai environment officer Phuchong Insompan said the hotline 05 34... on outdoor fires had received 60 calls since January 1, with roadside forest fires the most frequently reported, especially in Mae On, Chiang Dao and Chaiprakan districts. In March fire-prevention officials will be dispatched to Hot district, where farmers are expected to burn some 10,000 rai of woodland to plant maize.
