Singapore haze watch: Air quality hits unhealthy levels in four regions; north stays moderate
SINGAPORE, Sept 30 — Air quality in northern Singapore improved overnight, falling back into the moderate range at...
Singapore's air quality has deteriorated in four regions, with the 24-hour Pollutant Standards Index (PSI) staying in the unhealthy range. At 8am on Wednesday, September 30, PSI levels ranged between 112 to 118 in eastern, southern, western and central Singapore. One-hour PM2.5, a measure of fine particulate matter, is elevated in all five regions, with eastern Singapore recording the highest concentration at 79.
The health impact of haze depends on an individual's health status, the PSI level, and the duration and intensity of outdoor activities. NEA advises that healthy individuals should limit strenuous outdoor activities for an hour if the one-hour PM2.5 concentration is elevated, while vulnerable persons should avoid such activities.
The National Environment Agency expects Singapore's 24-hour PSI to remain in the high-moderate to mid-unhealthy range due to persistent smoke haze from fires in Kalimantan and southern Sumatra. Dry conditions are forecast to continue over these areas, and prevailing easterly or south-easterly winds will likely carry the smoke towards Singapore.
