Air quality hits unhealthy range in central Singapore
Air quality in central Singapore reached unhealthy levels on Saturday due to smoke haze drifting from fires in Sumatra and Kalimantan. Authorities have advised vulnerable groups to minimize outdoor activities as dry weather conditions persist.
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.
