The air quality has improved, down from an unhealthy 0.8 parts per million (PPM) on Friday to 0.1 PPM yesterday, which was below the safe level of 0.2 PPM, according to the office’s head of chemical and hazardous item management division Phaitoon Ngammook. The area affected by pollution had also shrunk from a 10km radius to a 300-metre radius.
As lingering foul smell may cause small children and the elderly to vomit or have skin and eye irritation, he said. Chom Thong District Office has set up a remedial centre so people can seek help if needed.
