Wide areas of Lampang, Mae Hong Son and Phrae provinces have been blanketed with haze that the public health office says could be hazardous.
The recorded levels of particulate matter smaller than 10 microns (PM10) in those areas have exceeded the safety limit of 120 microgrammes per cubic metre (ug/cu m), said Prayad Ananpradit, secretary of the command centre in charge of tackling air pollution in the nine upper northern provinces.
Phrae had the highest level of PM10 on Thursday, with dust particles reaching 205 ug/cu m, followed by Lampang with 159 ug/cu m and Mae Hong Son with 142 ug/cu m.
