Air quality back to moderate across Singapore after central region hits unhealthy range
There remains a risk of smoke haze affecting Singapore, with the 24-hour PSI forecast to be in the high-moderate to low-unhealthy range, the National Environment Agency said on Saturday.
Singapore's air quality improved to the moderate range on Saturday, Oct 3, after the central region's 24-hour Pollutant Standards Index (PSI) crossed into the unhealthy range, according to the National Environment Agency (NEA). The PSI in the central region reached 100 at 11 pm, while readings in the east, west, south, and north were 93, 89, 83, and 76, respectively. Hourly PM2.5 readings were also normal across all five regions.
The NEA reported moderate to dense smoke plumes from southern Sumatra and smoke haze from Kalimantan drifting towards Singapore and the surrounding area. For healthy individuals, the agency advised reducing prolonged or strenuous outdoor physical exertion if the 24-hour PSI is in the unhealthy range. Elderly people, pregnant women, children, and those with chronic lung or heart disease were advised to minimize such activities.
The NEA stated that health impact depends on a person's health status, PSI level, and duration/intensity of outdoor activity.
People should refer to 1-hour PM2.5 readings for immediate outdoor activities and use the 24-hour PSI forecast and health advisories when planning outdoor activities for the next day. A 24-hour PSI reading of 101-200 is considered unhealthy, 201-300 is very unhealthy, and above 300 is hazardous. The 1-hour PM2.5 reading is classified in four bands: normal (56 or below), elevated (56-150), high (151-250), and very high (above 250).
