Chiang Mai and Lampang suffer 'code red' air pollution

Chiang Mai and Lampang on Friday were choking on “code red” air pollution with PM2.5 levels above 90 micrograms (mcg) per cubic metre of air, according to the Pollution Control Department (PCD).

Northern and northeastern provinces also cited PM2.5 levels beyond the Thai safety limit of 50 mcg. 
Greater Bangkok enjoyed a respite from haze, having PM2.5 levels within the safe range at 12-35 mcg, which were predicted to drop further on Saturday thanks to various dust-tackling measures, the PCD said.
The PCD daily update on haze situation in the North, as of 9am on Friday, cited the PM2.5 levels between 33-100 mcg with the "code-red" status reported at tambon Chang Kerng of Chiang Mai's Mae Chaem district (100 mcg) and at tambon Phra Baht of Lampang's Mueang district (93 mcg).
The "code-orange" status was reported in tambon Chang Pheuk (61 mcg) and tambon Sri Phum (57 mcg) of Chiang Mai's Mueang district; in tambon Ban Dong (71 mcg) and tambon Mae Mo (67 mcg) of Lampang's Mae Mo district; tambon Ban Klang in Lamphun's Mueang district (88 mcg); tambon Nai Wiang in Nan's Mueang district (62 mcg); tambon Na Chak in Phrae's Mueang district (67 mcg); tambon Jong Kham in Mae Hong Son's Mueung district (59 mcg); and tambon Mae Pa in Tak's Mae Sot district (63 mcg).
In the Northeast, the PM2.5 level rose beyond the safety limit in tambon Nai Mueang of Khon Kaen's Mueang district at 67 mcg. 
The agency urged people to refrain from outdoor burning to help reduce the haze problems. Updates on air quality are available on the website and the phone app "air4thai”.
