Five northern provinces are currently experiencing unsafe levels of minute dust particles in the atmosphere, according to the Pollution Control Department (PCD).
The particles referred to by the department are PM10 (particulate matter 10 micrometres) or smaller.
Lampang had the highest reading, at 235.3 micrograms per cubic metre of air. Safe levels of PM10 particles are considered to be 120 micrograms per cubic metre or less.
The four other provinces with seriously high levels of particles were Phrae (218.08 micrograms), Lamphun (192.1 micrograms), Phayao (123.5 micrograms) and Chiang Rai (123.5 micrograms).
“The excessive level of these small dust particles can affect the health of locals,” Chukiat Pongsiriwan said yesterday in his capacity as head of Phrae’s Natural Resources and Environment Office.
The PCD measured levels of small dust particles in the North yesterday as part of its airquality monitoring operations. To tackle the problem, the PCD called on authorities to prevent people from burning garbage, agricultural scraps and dry leaves.
