Air Pollution Hits Record Levels in Singapore

On June 19, NASA's Terra and Aqua satellites captured striking images of the wildfires' smoke from space.

  

Wildfires burning on the Indonesian island of Sumatra have sent a choking haze over Singapore, pushing air pollution to record levels.

At 12:00 p.m. local time (04:00 GMT) Friday (June 21), the Pollution Standards Index — a scale of 0 to 500 to measure air pollution — hit 401 in Singapore, the highest in the country's history. Before this week, the record had been 226, set in 1997. By 10:00 p.m. Friday, the pollution index had dropped to 153, which is still considered in the unhealthy range of air quality.

The impenetrable smog enshrouding the city could be life-threatening; officials have closed schools and urged residents to wear protective face masks or stay indoors, especially elderly, pregnant women, children and people with chronic medical conditions.
