PETALING JAYA: Air quality in Miri, Sarawak, has remained at hazardous levels all day, although it eased by a few points on the Air Pollutant Index by 9pm.
The level had dropped to 375 from 391 at 1pm. Levels above 300 are classed as hazardous.
The Sarawak disaster management committee has said the hazy conditions were caused by wildfires in the Kuala Baram area and were temporary in nature.
“We will continue to monitor the situation over the next 24 hours,” the committee said in a statement today.
Elsewhere, “unhealthy” conditions were reported at Samarahan (101) and Sekolah Kebangsaan Kuala Baram 2 (139) in Sarawak and Johan Setia (112) in Selangor.
Air quality remained at “moderate” levels in most parts of the Peninsula and East Malaysia.
Kedah and Perlis were the only places with “good” air quality, with levels under 50 recorded in Langkawi, Sungai Petani, Alor Setar and Kangar.
In Selangor, readings average between 73 and 85.
The Environment Department has said that peat fires in Kuala Baram, Miri, caused a spike in the API reading for the area.
The Asean Specialised Meteorological Centre in Singapore and the US National Oceanic Atmospheric Administration have reported a total of 93 hotspots detected in Kalimantan, four in Sumatra, and three in Mukah and two in Sibu, Sarawak.
