Exploring the Unpleasant Aroma of Chlorine in Swimming Pools: A Scientific Perspective

Swimming pools, a popular summer attraction, are often associated with the refreshing scent of chlorine. However, many pool-goers have experienced an unpleasant odour that is far from the bleach-like aroma. This odour is not the smell of chlorine itself, but rather the result of a group of chemical compounds known as chloramines.

Chloramines are formed when chlorine disinfectants react with contaminants such as sweat and urine. In pools, the more ammonia present, the more dichloramine and trichloramine will form, intensifying the "pool smell." These specific compounds are responsible for the unpleasant odour in pools.

The formation of dichloramine and trichloramine is a result of inadequate pool maintenance and improper disinfection practices. This issue is particularly prevalent in public swimming pools, where the strong odour can be a clear indication that somebody (or many bodies) probably peed in there.

Indoor pools, particularly those that are poorly ventilated, are more likely to have a strong odour due to the formation of chloramines. The question of how much urine is present in pools arises due to the formation of dichloramine and trichloramine.

Monochloramine, dichloramine, and trichloramine are chemical compounds that form when chlorine disinfectants react with ammonia from sweat and urine. While monochloramine isn't problematic and is sometimes used to disinfect drinking water, dichloramine and trichloramine are more unpleasant smelling and can potentially harm swimmers' eyes and respiratory systems.

The search results do not provide information on who uses the swimming pool where chloramine traces are most detectable or the measures taken to reduce the odour. This highlights the importance of maintaining pool hygiene and proper disinfection practices to ensure a pleasant swimming experience for all.

In conclusion, the unpleasant odour in swimming pools is primarily caused by chloramines, which form when chlorine disinfectants react with contaminants such as sweat and urine. By maintaining proper pool hygiene and disinfection practices, pool-goers can enjoy a refreshing and odour-free swimming experience.
