PETALING JAYA: The haze has visibly returned to the Klang Valley despite the fact that Air Pollutant Index (API) on the Department of Environment’s (DOE) website reported ‘good’ to ‘moderate’ readings.

Residents noticed a sharp drop in the air quality Monday and could smell it in the air, with several parts in Kuala Lumpur and Selangor recording poor visibility.
