Haze levels across Singapore remained in the “unhealthy” range on Sunday (15 September) afternoon.

As of 4pm, the 24-hour Pollutants Standard Index (PSI) readings stood at 104 in the north, 102 in the central and eastern regions, while it was higher in the south (109) and west (110), according to the National Environment Agency’s (NEA) haze microsite.

The one-hour PM2.5 concentration reading for the same time stayed in the “elevated” range, from 56 in the north to 67 in the south. PM2.5 readings indicate the amount of particulate matter in the air, which the NEA says is a better measure of air quality. Just a day earlier, PSI readings tipped into the “unhealthy” range for the first time since 2016. The PSI range for “unhealthy” air quality is from 101 to 200.

During periods when PSI levels are “unhealthy”, members of the public are advised to reduce, minimise or avoid prolonged or strenuous outdoor physical exertion.
