SINGAPORE – Singapore's smog index hit the critical 400 level on Friday, making it potentially life-threatening to the ill and elderly people, according to a government monitoring site.
The level was reached at 11 am (0300 GMT) after a rapid rise in the Pollutant Standards Index, which measures the haze crisis caused by Indonesian forest fires.
The previous Singapore air pollutant index high of 226 was recorded in September 1997 at the height of a Southeast Asian calamity also resulting from vast amounts of haze from Indonesia, where slash-and-burn farming generates large amounts of smoke during the dry season that begins in June.
