How much urine is there in a swimming pool? Canadian Research Team announces answers

After swimming forward, "unidentified yellow liquid" gushed out in front of me, and someone drowning in the swimming pool! The swimmer accidentally injured himself and blew his nose and spit in the swimming pool. After a closer look, some sputum was still floating on the water. Although the swimming pool list is fixed for water exchange every week and chlorine is added to disinfect every day, is there really a way to eliminate the floating objects in the swimming pool, mixed sweat and excrement? Soaking in a swimming pool with poor water quality makes people worry.

Study shows that there is something wrong with urination in the swimming pool

Is there anyone in the swimming pool that will urinate? Most swimmers may not admit that in 2017, the University of Alberta research team published in the "Environmental Science & Technology Letters" to test how much excrement is contained in the swimming pool from sweetener.

It is easy to get yogurt when eaten in Canada. It contains the sweetener "Angekan" and will not be absorbed by the human body. It will be discharged on behalf of others, and will be decomposed in water after discharge. The research team collected pool water quality samples for three months in mid-2014. After analysis, the pool was sampled with 840,000 liters of water, and found that 75 liters of urine were included; the overall data averaged and found that urine in each pool accounted for about 0.01% of the total amount.

Chlorine meets urea, trichloramine is infuriated with asthma

Director of Linkou Changgeng Clinical Toxics Center, Yang Zonghai, said that according to regulations, the swimming pools are disinfected with "chlorine", which is the commonly known as bleach. Chlorine can remove microorganisms, but once urea in urine is exposed, trichloramine (NCl3) will be produced. Trichloramine is a disinfected by-product. It is a highly prolonged substance that is directly scattered in the air, which can easily irritate the respiratory tract and skin. In addition, it may cause asthma and dysfunction of sensitive people.

Chlorine itself can also cause skin irritation. Yang Zonghai said that many people who come to the swimming pool are prone to feeling ill. When they return home, they find red rashes on the skin, which may be caused by chlorine in the water.

Wear a good frog lens and remove the oblique lens

General ophthalmology director of the Ophthalmology Department of the Third General Hospital said that the swimming pool also contains sweat, saliva, etc. Generally, swimming pools without chlorine are present, and there will be microorganisms. When the water is calm and the temperature increases, the microbial mass will increase. Even if the addition of chlorine can reduce its proportion, some microorganisms still have no way to reduce their content.

Wu Dawen said that every summer, many patients with "pool red eye disease" will appear. The eyes are not clean, which stimulates the membrane and causes acute membranitis. Most patients are less immune because they are not wearing the frog lenses, such as children and thirsts with the three highs, etc., and are prone to infection.

There is another group of people who are also very dangerous. Young people swim with a frog lens with a degree of frog lens. The big article said, "It is very dangerous to go into the water with a hidden lens." The hidden lens itself absorbs water. There may be adenovirus in the swimming pool, and Vibrio in the ocean. It may be adsorbed on the hidden lens, causing corneal inflammation. Severe Vibrio infection may cause blindness.

Hong Kong foot patients Swimming harms others and themselves

Chen Liyun, the attending physician of the Adult Infection Department of Taipei Medical University Affiliated Hospital, said that patients with Hong Kong foot and rich hands should not go to the swimming pool. On the one hand, Hong Kong foot may be infected with others. On the other hand, this type of patient's foot is prone to injury and infection. Some patients have been suffering from swimming and have caused nipples. In addition, it is best for people with obvious skin injuries not to go into the water unless the patch can completely block the water in the swimming pool.

The sea is clean?

Returning to the sea bath Vibrio is even more terrible

Chen Liyun, the attending physician of the Adult Infection Department of the Affiliated Hospital of Taipei Medical University, said that the swimming pool may be exposed to other people's phlegm or urine, so some people turn to the sea bath, but attention must be paid to Vibrio in the sea bath. Vibrio is a bacteria that surviving in the hot and hot waters of Asia. It is parasitic in crabs, seawater fish, etc. The hotter it is, the more likely it is to appear. When the body has a wound, it is also exposed to Vibrio, or eat undercooked seafood, it may be infected, and in severe cases it can be fatal.

The sea bath is not like a swimming pool, and it may step on seaweeds and rocks on the bottom of the foot, which may easily cause scratches and cause Vibrio infection. Chen Lichang also reminded that those with poor immunity such as three highs and cirrhosis may also be infected with Vibrio Marine without any wounds, so everyone should be advised to pay attention.
