Air quality in central Singapore back in unhealthy range
Air quality in Singapore has reached unhealthy levels across four of its five regions due to smoke plumes drifting from fires in Indonesia. The National Environment Agency expects the haze to persist as prevailing winds continue to blow from the southeast.
Why it matters
Poor air quality poses significant public health risks and highlights the ongoing regional challenge of transboundary haze.
The Pollutant Standards Index in Singapore's southern region entered the unhealthy range at 10pm, after the eastern, western and central regions crossed the threshold earlier.
