Why it matters
This is not the case anymore. We now know that chlorine by-products are dangerous for swimmers, especially children. Chlorine by-products like chloroform and tri-chloramines are linked to asthma and cancer. Authorities in most countries now strictly regulate chlorine by-product levels. Today water treatment in pools is all about creating a chlorine by-product free swimming environment, and at the same time clean blue water with well-distributed chlorine. Scientific perspectiveIt all started with the Belgian professor Bernard who formulated the pool chlorine hypothesis in 2006: The hypothesis postulated that ”the rise in childhood asthma in the developed world could result at least partly from increasing exposure of children to toxic gases and aerosols contaminating the air of indoor pools”. Since then many scientific studies have been published both supporting and rejecting his pool chlorine hypothesis.
In 2011 the German health authorities (Umwelt Bundes Amt) found that evidence was sufficient to put out a press information on their homepage warning families with asthma and allergies about the by-product asthma risk. The press information especially suggested that these families not to take their children to baby swimming due to exposure of by-products to their underdeveloped lungs. InBlue is the first concept in the world rethinking water treatment in pools, creating almost by-product free water and air. |
