Swimming pool chlorine is harmful to human body

Chlorine is a toxic gas with a strong irritating odor, but it is not useless. On the contrary, it plays an important role in many aspects, the most common of which is disinfection. If you like swimming, you will smell a pungent smell in the swimming pool. This is chlorine, which has the function of disinfection. After all, it is toxic, and many people are worried about its impact on health. So, what harm does swimming pool chlorine do to the human body?

The water quality testing contents of swimming pools include turbidity, pH value, free residual chlorine, total colony count, etc., which are all stipulated by national mandatory standards. The current national standard stipulates that the residual chlorine content in swimming pools is 0.3mg/L to 0.5mg/L.

Will the chlorine preparations remaining in the pool water be harmful to the human body? If they are qualified organic preparations and the residual content in the swimming pool does not exceed the corresponding indicators, they are safe. On the contrary, too high chlorine content will cause a certain degree of harm to the human body.

The main hazards of excessive residual chlorine concentration in water are:

1. It is highly irritating and harmful to the respiratory system.

2. It is easy to react with organic matter in water to produce carcinogens such as chloroform.

3. Damage to skin cells and intercellular matrix, easily causing dry skin, chapped skin, papules, acne, aging, or changes such as palm keratinization and thinning of nails

When disinfecting swimming pools, chlorine disinfection and ozone disinfection should be combined to achieve a synergistic effect.

The chlorine disinfection method is to add chlorine directly into the water, which can kill pathogenic microorganisms immediately. It is more effective and faster, and is more suitable when there are many people.

Ozone disinfection requires a period of time. First, the water must be collected into the ozone reaction tank through a circulating filtration device, and then the ozone is pumped into the reaction tank to combine the ozone and swimming pool water. Only after the reaction is complete can the microorganisms be killed. If there are pathogenic microorganisms in the swimming pool during this period, it is impossible to pump the pathogenic microorganisms into the reaction tank at the first time.

But ozone can have a very positive impact on water quality. After disinfection, the water will be particularly blue and very beautiful. Therefore, it is recommended that swimming pools combine the two disinfection methods.

suggestion:

When swimming, citizens must choose a regular, large swimming pool with circulating filtration equipment and disinfection facilities. For children, their eyes and skin mucous membranes are relatively delicate. When swimming, try to let your children wear a swimming ring and swimming goggles. Try not to immerse their heads in water. They must take a bath after swimming.

At the same time, citizens should also pay attention to their own quality when swimming, take a shower before entering the swimming pool, soak their feet and wear a swimming cap when entering the swimming pool; in addition, owners of swimming pools should change the water frequently and pay attention to disinfection to ensure the health of the public.
