Singapore haze eases in west but central region remains unhealthy

Singapore's air quality has shown slight improvement, though the central region remains in the unhealthy range due to transboundary haze. The National Environment Agency warns that smoke from fires in Sumatra and Kalimantan may persist due to dry conditions.
Why it matters
Transboundary haze is a recurring environmental and public health issue in Southeast Asia that requires regional cooperation to mitigate.
Malay Mail SINGAPORE, Sept 5 — Singapore's air quality improved on Saturday morning, with the western region returning to the moderate range after briefly recording unhealthy levels earlier in the day.
At 9am, the 24-hour Pollutant Standards Index (PSI) – similar to Malaysia's Air Pollution Index – stood at 115 in the central region, while the west recorded 98 and the east 96, The Straits Times reported.
The west had entered the unhealthy range at 102 at 7am, making it the third region in Singapore to breach the 101 threshold since Friday.
The north and south remained in the moderate range, with readings of 83 and 87 respectively.
Singapore's National Environment Agency (NEA) considers PSI readings of 101 to 200 unhealthy and advises people to reduce outdoor activities at such levels.
