The Pollution Control Department (PCD) has advised people to stay indoors if smog is visible. Or if they really need to go out, they should wear face masks.
PCD director general Wichien Jungrungruang revealed Monday that the amount of particulate matter of up to 10 micrometres in size (PM10) soared to 244 micrograms per cubic metre of air near highways in Samut Sakhon.
“It’s way above safe levels,” he said. The PM10 amount should be less than 120 micrograms per cubic metre of air.
