SERDANG (Bernama): Air Pollutant Index (API) readings issued by the Environment Department (DOE) are averages over 24 hours and have no direct correlation with visibility range, says Datuk Seri Dr Wan Azizah Wan Ismail.
The Deputy Prime Minister said API readings channelled by DOE via Air Pollutants Index Malaysia (APIM) are the country's official API readings and the data was verified first before displaying to the public.
