The secret of swimming pool water contains toxins

Let's find out the chemical composition of swimming pool water to find out how to know if swimming pool water is toxic or non-toxic through the following article.

Swimming pool water and chemical composition .

There is a fact that not many people notice, it is the swimming pool (especially outdoor pool) which is considered one of the most polluted places. These tanks often come in contact with the outside environment, easily infected by dirt, germs, spores in spores, bird feces .

In addition, the pollution source to the pool also includes microorganisms, the amount of oil excreted on the body of people swimming such as sweat, cosmetics, sunscreen, urine, saliva .

Swimming pool is considered one of the most polluted places.

Therefore, swimming pools must be chemically treated before being put into use. An indispensable ingredient in swimming pool water usually includes chlorine. This is a chemical used to disinfect, destroy components that contaminate tank water.

Chlorine is used in two main forms: calcium hypochlorite (solid) and sodium hypochlorite (liquid) . These two compounds work with water forming hypochlorous acid . This acid kills bacteria and pathogens by breaking the lipid membrane, destroying enzymes and larvae inside bacterial cells through oxidation.

Hypochlorous acid is easily decomposed when exposed to ultraviolet light from sunlight.

However, hypochlorous acid is easily degraded when exposed to ultraviolet light from sunlight. Therefore, to ensure effective treatment of tank water, it is often added cynanuric acid, which reacts with free chlorine in hypochlorous acid to form a more stable compound.

Finally, to maintain the pH balance of tank water, alkaline chemicals like sodium carbonate or sodium bicarbonate are used. A standard water pool must have an average pH of 7.2 - 7.8 according to the Langelier Saturation Index.

Some swimming pools are added with greening chemicals to resemble seawater.

In addition, some swimming pools are added with green chemicals, creating effects for swimming pool water like sea water but not harmful to users.

Process of swimming pool water treatment

In order to get comfortable moments in the swimming pool, cleaning and treating swimming pool water is always a top priority. Depending on the frequency of use, tank area and weather and environmental conditions, each swimming pool has different ways of cleaning tank water. However, achieving the above process must achieve the following:

Firstly, it is necessary to regularly check the pH of the pool water. Water with a pH too low or too high has a very bad effect on the health of users. One thing is not well known, the unpleasant smell that is common when swimming is not because the tank is given too much chlorine. To deal with this situation, even adding more chlorine to the tank can be solved.

Cleaning and treating swimming pool water has always been a top priority.

Secondly, swimming pool water hygiene should pay attention to both tank hygiene. That means having to regularly discharge pool water, disinfect the tank with chemicals. This work eliminates the possibility of moss, algae causing disease in the pool water when used

Third, we need to clean the pool water filter. The pool water before being put into use needs to go through a sand or humus filter to eliminate the pollutants initially. However, it is also this filter that should be regularly cleaned and cared to avoid the situation of accidentally causing pollution to the water tank.

Impact on human health and recipes for safe swimming

Non-standard swimming pool water is considered a god for human health. Non-sterile swimming pools will be a habitat for many types of bacteria such as Cryptosporidium - the main cause of human diarrhea or Chlamydia Trachomatis - the killer of ocular conjunctivitis.

In contrast, swimming pools containing too many disinfectants cause skin and eye irritation because of the large concentration of chlorine and low pH.

Non-standard swimming pools will be a habitat for many harmful bacteria.

In particular, chlorine used in large quantities can cause a lot of danger to swimmers. US scientists have conducted water collection experiments in public swimming pools and tap water to see if the level of genotoxicity (the process of causing DNA changes).

The results demonstrate that water samples with too much chlorine in swimming pools affect DNA completely superior to tap water. In addition, in indoor swimming pools, excess chlorine in the water cannot escape, easily irritating the swimmers' respiratory system if too much is inhaled.

When swimming, if you see a lot of swimmers, you need to consider whether or not you should continue to swim.

To go swimming safely, you need to watch your swimming pool coming up. If the tank has a moderate number of people, water while looking with the naked eye and without smell, it is a usable pool. Conversely, if the swimming pool is cloudy or has a characteristic shocking chlorine odor, the number of swimmers is much to consider whether or not to continue swimming.

In addition, no matter what swimming pool you are in, you should take a shower before going to the pool to limit sweat, cosmetics . on the body - potential substances to contaminate swimming pools. At the same time, you need to use tight swimming goggles, to avoid pool water from entering your eyes, as well as to clean your body with eye drops, earrings after swimming to avoid contagious diarrhea, conjunctivitis .

When swimming, you should use tight swimming goggles, avoiding pool water from entering your eyes.

Another small note is that you should not urinate under the pool . Recent research has shown that compounds in urine combined with chlorine can cause many adverse health effects such as genetic cell damage, asthma, cancer .
