BATU PAHAT, JOHOR, 7 OCTOBER 2026 —
Twenty-eight areas across Malaysia recorded unhealthy air quality as of 3pm yesterday, with Batu Pahat in Johor registering the highest Air Pollutant Index (API) reading of 194, according to the Malaysian Air Pollution Index Management System (APIMS).
Market Impact
Nilai and Segamat in Negeri Sembilan and Johor respectively followed at 170, matched by Pasir Gudang and Tangkak at the same level. Seremban and Kluang both recorded 168, while Larkin stood at 166. Bandaraya Melaka logged 163, Putrajaya 162, Kota Tinggi 160 and Pengerang 159. Indera Mahkota in Kuantan also hit 159.
Cheras recorded 158, with Balok Baru in Kuantan and Johan Setia in Selangor at 157. Bukit Rambai reached 156, while Batu Muda, Shah Alam, Alor Gajah, Jerantut, Kemaman and Paka all showed 155. Banting came in at 154, Petaling Jaya at 153, and Port Dickson and Rompin at 152. Klang was the only listed area in the moderate band at 124.
All 28 areas fell within the 101–200 range classified as unhealthy. The API scale rates 0–50 as good, 51–100 as moderate, 201–300 as very unhealthy and above 300 as hazardous, according to the Department of Environment framework cited by Utusan Malaysia.
The readings come from APIMS, the official monitoring network operated by the Department of Environment under the Ministry of Natural Resources and Environmental Sustainability. Utusan Malaysia reported the figures based on the 3pm update.
Prolonged unhealthy air typically prompts health advisories for sensitive groups and can restrict outdoor work in construction, logistics and plantation sectors, affecting daily output and project timelines. The Department of Environment updates APIMS hourly; the next scheduled release will show whether conditions have improved or deteriorated.
