Bush fires sparked by hot and dry weather are suspected to be the main culprit of Malaysia’s air quality veering into unhealthy levels.
Sabah's Department of Environment (DOE) has warned the public against carrying out open burning after the air pollution index (API) in two districts here reached an unhealthy level.
As of Saturday, Kota Kinabalu and Kimanis stations have recorded API of over 100.
The southeastern Rompin in Pahang and southwestern Banting in Selangor have registered unhealthy API readings of 171 and 102 respectively, according to the Department of Environment.
Rompin’s declining air quality is suspected to be related to the sustained wildfires in the adjacent Pekan since March 11.
While 62 API stations nationwide have recorded moderate readings, while only two stations saw good air quality. No stations recorded hazardous readings.
A heatwave is expected to last over three consecutive days, hitting nine state and 21 areas.
Affected areas include Chuping in Perlis; Kota Setar, Sik, Baling and Kulim (Kedah); Hulu Perak, Kuala Kangsar, Kinta and Batang Padang (Perak); Jerantut, Raub, Temerloh, Maran and Bentong (Pahang); Sepang and Petaling (Selangor).
Also listed are Port Dickson (Negri Sembilan), Melaka Tengah (Melaka), Tangkak in Johor and Kuala Lumpur.
