Singapore haze: Air quality remains unhealthy across country; PM2.5 readings normal in all regions
Air quality in Singapore has shown improvement, with most regions moving into the moderate range after a period of unhealthy haze. The National Environment Agency continues to monitor hotspots in Kalimantan and surrounding areas.
Why it matters
Transboundary haze is a recurring environmental and public health issue in Southeast Asia that impacts regional economic activity and quality of life.
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.
