Hotspots and haze in parts of Indonesia have led to a deterioration in air quality. The Pollutant Standards Index, or PSI, has been affected as a result.

The PSI crossed into the unhealthy range at noon, indicating a decline in air quality. This change is attributed to the persistence of hotspots and haze in the region.

Further information on the current air quality situation is available from the source, providing updates on the PSI and its implications.
