Who is at risk?
Whether you are participating in swimming or just poolside providing moral support, the quality of the air around you is just as important for your health as the quality of the water you swim in.
On top of the myriad of exposure symptoms swimmers can suffer following a visit to an indoor pool, long term exposure to poor air quality can also cause hypersensitivities. Even professional swimmers have been hospitalised in the past thanks to severe exposure symptoms.
Does the air around the swimming pool you visit smell strongly of Chlorine?
If you answered ‘yes’ it’s important to know that the odour is not pure Chlorine, but rather a form of Chloramine (waste products combined with Chlorine), a by-product of Chlorine, called Trihalomethanes (THM). THM are not only dissolved in the water where they can be absorbed through the skin or ingested but are also present in gaseous state that can be inhaled.
Chloramine gas is heavier than air, which means the bulk of the THM settle right where they can cause the most problems for swimmers. The level of THM in the air significantly rises as swimmer activity in the pool increases due to the surface tension of the water being broken, releasing the THM. A research paper by the Institute of Hygiene at the University of Heidelberg concluded that only 1/3 of THM uptake was by the skin while the remainder was via the respiratory pathway. A fact sheet from The Department of Environmental Services also reported short and long term affects to the central nervous system, bladder, kidneys and liver following exposure to THM.

In light of the above, swimmers, onlooking parents, swim instructors, lifeguards and site operators are all exposed to the health risks associated with a swimming pool. There are a couple simple things swimmers can do to help lower the risk of Chloramines forming such as showering before swimming and utilising the restrooms however the solution to removing the health risks lies with the facility owner/s taking action. Most facilities cannot afford losing customers or acquiring a bad reputation just because of air quality issues that can be resolved by using adequate equipment and maintenance techniques.
