Officials have blamed farmers and households who defy the ban on outdoor burning as the "main cause" of the haze problem, and pledged tough action on those who continue such practices. A neighbouring province, Khon Kaen, is also suffering from a significant drop in air quality, although PM2.5 levels had slightly improved as of Monday. "The pollution warning have been changed from red to orange, but we will continue to closely monitor air quality," said Khon Kaen governor Somsak Changtrakun.
