In a joint statement, Paris 2024 organizers and World Triathlon said they had taken the decision to cancel Monday's swimming training session because "water quality levels... do not present sufficient guarantees" to allow it to take place.
The triathlon is the first Olympic event due to be held in the Seine, before marathon swimming in the second week of the Games. A swimming training session slated for Sunday was also canceled due to the pollution levels.
The men's individual triathlon is scheduled to start on Tuesday at 08:00 (07:00 BST), with the women's individual event to be held on Wednesday.
The quality of the Seine's water is dependent on the amount of rain that falls in and around Paris.
