Haze in S'pore: PM2.5 reading in elevated zone for 1st time since Oct 27, at 57 in the west
PM2.5 readings for the rest of Singapore are in the normal range at 11am.
Air quality in Singapore worsened in the west on the morning of October 29, with one-hour PM2.5 readings reaching 57, marking the first time in that range since October 27. This is the first instance of the current air quality entering the elevated range in any of Singapore's five regions. By 11am, PM2.5 readings for the remaining regions were between 25 and 46, indicating normal values.
The 24-hour PSI readings, which reflect the air quality over the past 24 hours, remained in the good to moderate band, ranging from 69 to 78 at 11am on October 29. Good to moderate air quality is defined by a PSI range of 0 to 100, while unhealthy air quality is indicated by a PSI range of 101 to 200. When air quality crosses the "unhealthy" threshold, it is advised that people, particularly the elderly, children, and those with health concerns, limit their outdoor activities.
