Air quality hits unhealthy range in central Singapore; 1-hour PM2.5 elevated in 3 regions

Air quality in central Singapore deteriorated to the unhealthy range on Saturday morning, October 3, according to the Pollutant Standards Index (PSI). The PSI surged to 104 by noon, while readings in the other four regions stayed moderate. The 1-hour PM2.5 measurement at noon was elevated in the central and eastern areas. This surge in air pollution followed smoke haze drifting towards Singapore from southern Sumatra and fires in Kalimantan, as reported by the National Environment Agency (NEA).

Dry weather conditions were anticipated to continue over Singapore and the surrounding area, with the NEA forecasting a PSI in the moderate to low-unhealthy range for the day. Individuals with healthy health, older adults, pregnant women, young children, and those with respiratory or heart conditions were advised to limit prolonged or intense outdoor exercise when the PSI enters the unhealthy range.

The NEA emphasized that the health impact of haze depends on a person's health status, the PSI level, and the duration and intensity of outdoor activity.
