New Delhi, Oct. 15 -- Singapore's air quality deteriorated to an Air Quality Index (AQI) of 287, classified as unhealthy on a live air-quality dashboard, as smoke from Indonesian wildfires intensified across Southeast Asia. The reading showed PM2.5 concentrations of 116 micrograms per cubic metre and PM10 levels of 164 micrograms per cubic metre. Delhi, meanwhile, recorded an AQI of 165 at 9 am on Thursday, placing it in the moderate category, according to India's Central Pollution Control Board (CPCB).
