Glitch in Penang API readings

Tight landing: An aeroplane approaching Penang International Airport in Bayan Lepas for landing.

GEORGE TOWN: Although Penang was enveloped in a veritable smog on Tuesday afternoon, the Air Pollutant Index (API) readings for the state ranged between only 60 and 72.

Many Penangites on social media expressed disbelief at the API readings issued by Department of Environment (DOE) and began searching for alternative sources of information on the haze.
