Sarawak air quality worsens; Lundu hits API 169
What happened
Air quality worsened overnight in Sarawak, with seven areas recording unhealthy Air Pollutant Index (API) readings as of 8am Wednesday. This compares with only Serian at 5pm on Tuesday, according to the Natural Resources and Environment Board's (NREB) Daily Haze Watch.
Lundu recorded the highest API reading at 169, followed by Serian. The deterioration affected multiple districts across the state.
Why it matters
Unhealthy API readings indicate potential health risks, especially for vulnerable groups such as children, the elderly, and those with respiratory conditions. Prolonged exposure to haze can lead to respiratory and cardiovascular issues.
The worsening air quality may disrupt outdoor activities, schools, and businesses in affected areas. It also signals a possible escalation of transboundary haze, which has regional economic implications.
Impact on Sarawak
Sarawak's key industries, including tourism, agriculture, and construction, could face disruptions due to poor air quality. Reduced visibility and health advisories may affect worker productivity and visitor numbers.
The state government may need to issue health advisories and distribute masks, as well as consider emergency measures if API readings continue to rise. This places additional strain on public health resources.
Regional context
Sarawak has experienced recurring haze episodes in recent years, often linked to land and forest fires. The NREB's Daily Haze Watch is the primary monitoring tool for the state.
The API scale categorizes readings of 0-50 as good, 51-100 as moderate, 101-200 as unhealthy, and above 200 as very unhealthy. Lundu's reading of 169 is firmly in the unhealthy range.
Response and outlook
Authorities have not yet issued specific health advisories as of the report time. Residents are advised to limit outdoor activities and wear masks when necessary.
The NREB continues to monitor air quality across the state. Further deterioration is possible if wind patterns and fire activity persist.
Key takeaways
Seven areas in Sarawak recorded unhealthy API readings as of 8am Wednesday. Lundu had the highest API at 169, followed by Serian.
Only Serian was unhealthy at 5pm Tuesday, showing rapid overnight deterioration.
