The level of fine particulate matter in the air, known as PM2.5, on Saturday stood at between 31-80 micrograms per cubic meter in Seoul city areas. But meteorologists say this week it will exceed the daily safe level of 100 micrograms per cubic meter due to smog blown in by northwesterly winds from China.
