Singapore’s air quality worsened to a “very unhealthy” level as haze from Indonesian forest fires continued to drift across to the city state, according to pollution readings from the National Environment Agency.
The country’s 3-hourly pollution index rose to 222 at 5 p.m. local time from 190 at 4 p.m., the NEA said on its website. The agency forecast on Friday that prevailing winds from the “south-east or south” direction were capable of blowing denser haze across from Indonesia.
Forest fires in Indonesia are on track to become the worst on record, Agence France-Presse reported Friday, citing Robert Field, a Columbia University scientist based at the NASA Goddard Institute for Space Studies. Haze conditions in Singapore and southeast Sumatra are at levels close to those previously seen in 1997, AFP said.
