As a result of contact with this toxic mixture, the risk of developing certain increases pain, such as asthma or bladder cancer. It is the conclusion of a new study, published in the journal Environmental Science & Technology and taken over by MetroNews.fr.
The showers installed at the pools are not there by chance, but not everyone uses them before entering the pool, although it is mandatory. It is a big mistake, because this habit is not only unhygienic, but can be dangerous for health.
A previous study had already shown the danger of mixing chlorine and urine: apart from irritating skin, eyes and nose, inhalation of these gases could lead to respiratory disorders, asthma, rhinitis and bronchitis.
The new study by American researchers goes further, with scientists identifying mutagenic molecules that can affect DNA.
Piscina vs. contact lenses. Do you have to compromise?
Researchers at the University of South Carolina took water samples from 28 public and private pools and jacuzzis and compared water before and after use during normal and high-flow periods. After analysis, they identified over 100 by-products from the mixture of perspiration, urine and chlorine.
The more people enter the pool, the stronger its mutagenic potential. The people who enter the pool most often are also the most exposed to risk. For this reason, an increase in respiratory and respiratory pathologies was observed cancer to the bladder among professional swimmers and pool staff in the United States.
Goodbye to chlorine, the pool becomes “organic” and costs less
To take advantage of the presence in the pool without fear of disease, it is recommended to regularly change the water, taken before entering the pool and, of course, abstinence from urinating in water.
After testing in vitro samples, the results showed that the pool water was 2.4 times more dangerous than tap water. As for the water in the jacuzzi, it had a 4.1 times higher risk of causing cell damage.
