Organisers of the Singapore leg of the Fina Swimming World Cup announced their decision to cancel the WC finals scheduled for 6pm after the 3-hour PSI reading escalated towards the unhealthy range. This is the first time the FINA World Cup had been cancelled in Singapore since its inception in 2007.
In a statement made after 4pm, the organisers said: "At 4pm today the 3-hour PSI reading was 190. We've observed an upward trend in the 3-hour PSI reading and for the safety of all athletes, guests, officials, spectators, volunteers and staff, we have made the decision to cancel the finals scheduled for 6pm this evening.
"Spectators who have purchased tickets for this evening's session will be eligible for a refund."
Swimming fans will not be able to catch the hotly anticipated battle in the 200m backstroke between world champion Emily Seebohm, multiple Olympic champion Missy Franklin, and world 200m individual medley record holder Katinka Hosszu.
The trio will be awarded medals based on their fastest qualifier times.
