Pollution takes its toll on marathon field Twenty-two people were sent to hospital yesterday, two
remaining in critical condition last night, after taking part in Hong Kong's biggest marathon amid the worst air pollution since September.
Many of the record 40,000 runners complained the "choking" air affected their performance in the 10th annual Standard Chartered Hong Kong Marathon, half-marathon and 10km events.

Stratospheric Ozone DepletionStratospheric Ozone Depletion
October 1999 (average)Historically, the Antarctic ozone hole is largest during October. This image shows the data from the Total Ozone Mapping Spectrometer (TOMS) Earth Probe, for the month of October 1999.
September 17th 2001Satellite data show the area of the 2001 Antarctic ozone hole peaked at a size roughly equal to that of recent years about the same area as North America. Researchers have observed a levelling-off of the hole size and predict a slow recovery.
