Four Sarawak towns battle hazardous air quality as pollution surges

Four locations across Sarawak are experiencing 'very unhealthy' air quality levels, with Serian emerging as the worst-affected area in the state. The town recorded an Air Pollution Index (API) reading of 278, indicating hazardous conditions that pose significant health risks to residents and vulnerable groups.

The deterioration in air quality affects multiple towns across the state, with all four locations now classified in the 'very unhealthy' category. Readings at this level typically prompt regional authorities to issue health advisories and recommend precautionary measures for the public.

Residents in affected areas have been advised to limit outdoor activities and take protective measures. The 'very unhealthy' classification indicates that members of the general public may experience health effects, while those with respiratory conditions, children, and elderly persons face heightened risks.

The situation underscores ongoing air quality challenges in Sarawak, with pollution levels fluctuating seasonally. Authorities continue to monitor the conditions and have urged residents to stay updated on air quality forecasts to protect their health.
