JOHOR, 4 OCTOBER 2026 —
KUALA LUMPUR (Oct 3): Four areas in Johor and Sarawak recorded air pollutant index (API) readings at unhealthy levels as of 6pm on Saturday, according to data from the Department of Environment’s (DOE) Air Pollutant Index Management System (APIMS).
Market Impact
The highest reading was recorded in Pasir Gudang, Johor, at 155, followed by Larkin in the same state at 152.
In Sarawak, the Serian District Police Headquarters (IPD Serian) station recorded an API of 128, while Sri Aman registered 112. These four locations were the only areas to fall into the unhealthy category during the reporting period. Meanwhile, 60 other areas across the country recorded moderate API readings. Three locations reported good air quality: Taiping in Perak at 49, Langkawi in Kedah at 41, and Kangar in Perlis at 32.
The DOE categorises API readings of zero to 50 as good, 51 to 100 as moderate, and 101 to 200 as unhealthy. Readings between 201 and 300 are classified as very unhealthy, while those above 300 are considered hazardous. The data reflects the air quality status as of 6pm on Saturday, October 3.
The report highlights regional variations in air quality, with Johor and Sarawak bearing the brunt of the unhealthy readings. The presence of multiple moderate readings across 60 areas suggests widespread, though less severe, air pollution concerns. The lowest readings in Perlis, Kedah, and Perak indicate better air quality in those northern regions. The DOE’s APIMS data serves as the primary reference for public health advisories and environmental monitoring in Malaysia.
