SERIAN — Air quality in this Sarawak district has deteriorated sharply, with monitoring stations recording an Air Pollution Index (API) reading of 241, classified as 'very unhealthy' by environmental standards. The elevated pollution levels pose significant health risks to residents, particularly vulnerable groups including children, elderly persons, and those with respiratory conditions.

The concerning API reading underscores worsening air quality across Sarawak, with multiple districts experiencing degraded atmospheric conditions. Authorities typically recommend that individuals reduce outdoor activities when API levels breach the 200 threshold, and residents are advised to use appropriate respiratory protection when venturing outside.

The deterioration in air quality often correlates with transboundary haze, seasonal burning practices, and local industrial or vehicular emissions. State environment officials have been monitoring the situation closely as pollution levels continue to fluctuate across the region.

Residents in affected areas are urged to stay informed of daily API updates and take appropriate precautions to minimize exposure to hazardous air. Health authorities recommend consulting medical professionals for guidance on managing respiratory health during periods of poor air quality.
