Singapore haze: Air quality remains unhealthy in most regions; PM2.5 readings normal across country
Air quality in Singapore has improved to moderate levels following a period of unhealthy haze. The National Environment Agency expects conditions to remain stable as showers are forecasted for the coming days.
Why it matters
Transboundary haze is a recurring environmental and public health concern in Southeast Asia that impacts daily life and regional air quality standards.
Though the hotspot and smoke haze situation may improve in areas experiencing showers, it may continue to stay elevated in areas experiencing prolonged periods of dry weather, "with a continued risk of transboundary haze occurrence", NEA said on Sunday.
