At GP circuit, it's not just excitement that's in the air
The Marina Bay Street Circuit (pictured) will be the focus of motor sport fans around the world this weekend, when the Singapore Airlines Singapore Grand Prix takes place.
Hopefully, fans and participants will get a vastly improved view than what appears in this photo, taken yesterday after the island was shrouded in haze again.
The 24-hour Pollutant Standards Index stood at the 95-101 range at 8pm last night. A reading of 101 signals that the air quality has moved into the "unhealthy" range.
At the unhealthy range, prolonged or strenuous outdoor physical activity should be reduced. At moderate levels of 51-100, normal activities can still be carried out.
