In order to help disinfect pools all over the world from microorganisms and infections such as salmonella, Gastroenteritis, Legionnaires disease, ear infections, athlete’s foot and cholera or oxidize chloramines and dirt, many add chlorine to water, Chlorine destroys microorganisms and bacteria in a relatively uncomplicated chemical reaction. The chlorine solution that is poured in the water separates and breaks down into countless variant chemicals, such as hypochlorite ion and hypochlorous acid. Both of these chemicals are capable of killing many bacteria and microorganisms through assailing the lipids’ cell walls and demolishing the enzymes and property in the cell. this started in the 1800’s and has been a standard hence 1904 and has never been questioned until the 1970s when a group of scientists found out that chlorine can cause Trihalomethanes when added to water, as Trihalomethanes can increase the making of free radicals in the body which can be cancer causing. Today i will be talking about the advantages and disadvantages of adding chlorine to pool water.There are numerous advantages of using chlorine as a disinfectant. One of the advantages of chlorination is that it carries on killing bacteria as the chlorinated water travels through the water pipes to the valve. One of chlorine’s biggest advantages is making sure that there is sanitized water straight to the tap, while the effect of other sanitizers, for instance ultraviolet light, ozones and ultrafiltration only have a temporary effect.
besides purifying water, chlorine can also help get rid of unpleasant tastes and smells,in addition to this it can also limit the growth of algae in water pipes and water storage tanks, it can also help remove displeasing nitrogen mixtures that grow in water. “What we found is by analyzing blood samples and urine samples, we have an increase in risk markers related to cancer,” says scientist Manolis Kogevinas, she and her colleagues have studied chlorinated pools and found evidence that chlorinated water can cause cancer by evaluating 49 healthy adult bodies before and after they have swem in an indoor chlorinated pool for 40 minutes. Kogevinas is not the only reasercer that has studied in this field. On top of the fact that chlorine has many negative effects such as cancer, difficulty breathing, chest pains, cough, eye irritation, increased heartbeat, rapid breathing, and death, chlorine still is not very beneficial when added to water for disinfection.
the most common negative effect of chlorinated water is reported in Walkerton crisis may, 2000, when chlorine was not able to disinfect the pool water and drinking water, and therefore an epidemic of Escherichia coli pollution arose in the water system of Ontario in walkerton, canada. Where thousands of people began to experience nausea, malaise, vomiting and bloody diarrhea and even seven people passed away.
