The Department of Health said on Sunday that PM2.5 levels in several provinces had climbed into the “red” and “orange” zones, indicating serious and moderate health impacts. A further 28 provinces across the North, Northeast, Central Plain and western regions recorded orange-level pollution. “Pollution levels are expected to remain above safe limits this week due to stagnant weather conditions and an increase in open burning in several areas,” Dr Amporn said.
