PSI back in healthy range after 30 hours of haze: NEA

Air quality in Singapore returned to healthy levels at 2pm on Sunday (Oct 8) after around 30 hours in the unhealthy range, according to the National Environment Agency (NEA) website.

The 24-hour Pollutant Standards Index (PSI) first entered the unhealthy range in the east region at 7am on Saturday, said NEA on Facebook on Saturday evening.

"This was followed by the central region entering the unhealthy range at 11am.

"The Government’s interagency Haze Task Force convened this morning. Task Force agencies have rolled out their respective action plans and advisories for the protection of the health and well-being of the public."

Sharing a video of the haze taken from her flat at Northshore Drive in Punggol on Saturday morning, Stomper Renee said: "I was filming the haze from my window and spotted this bright red sun."

The haze originated from hotspots detected mostly over the southern and central parts of Sumatra on Friday. 

At 9pm, the PSI reading reached between 67 and 123. A PSI reading of 101 to 200 is in the unhealthy range, for which the NEA advises the public to cut down on outdoor activities.

It was the first time the PSI reading had ventured into the unhealthy range since 2019.

By 2pm on Sunday, it stood between 60 and 96, back into the moderate range.
