Air quality deteriorates across Sarawak amid hazardous pollution levels

Air quality has deteriorated significantly across multiple districts in Sarawak, with the Department of Environment flagging hazardous pollution levels in at least four major areas. Serian recorded the most severe readings, while Kuching, Sri Aman, Samarahan and Sarikei also registered unhealthy air quality indices.

The hazardous air quality poses potential health risks to residents across the affected districts. Authorities typically advise the public to limit outdoor activities and use protective masks during periods of hazardous air quality.

The Department of Environment did not immediately disclose the specific causes of the pollution spike or provide details on expected duration of the poor air quality conditions. Residents in affected areas have been urged to monitor official air quality updates and take necessary precautions.

Sarawak has experienced recurring air quality issues in recent years, often linked to transboundary haze from regional sources. The current pollution levels underscore ongoing environmental challenges facing the state.
