How much urine is there in the swimming pool? The research results are so amazing that scientists can't believe it?

Sunny and warm summer days are always beautiful. Many people will bring their relatives and friends to play together. The most common thing is to go to the water park, swimming pool or take a shower together. Although my friends and I always joke about whether anyone pees in the pool secretly, it has never been scientifically tested, but researchers in university of alberta, Canada, made one. Interesting? In the experiment, the test results stunned a group of researchers. So is the water in the swimming pool clean and how much urine is there?

Researchers in university of alberta found a way to test the urine content in swimming pools, and began to investigate and test 3 1 swimming pools in Canada. The researchers' method is to measure the urine content in swimming pools. Sweetness? Test urine content. There will be residual sweeteners in human urine, because the foods we eat generally contain sweeteners, which are digested and decomposed in the human body and then excreted with urine. Researchers in university of alberta started the test from this aspect.

In this 3 1 swimming pool list, both public swimming pools and private small swimming pools contain a certain amount of urine, and more than a little. The results of this study show that the urine content in the smallest swimming pool is 30 liters, and the most terrible thing is that in a super-large swimming pool with a water capacity of 830 thousand liters, the urine content is about 75 liters! That is, in this swimming pool, the urine content is about 0.0 1%. So what is 0.0 1%? The volume of a drop of oil we usually use for cooking is about 0.05ml, and 0.0 1% is equivalent to this drop of oil falling into a 500ml mineral water bottle. Although these researchers did not publish the list of swimming pools tested, they also announced that this situation is not a special case, because almost every public swimming pool has almost 60 liters of urine on average!

The researchers did not stop after testing the swimming pool, but turned to testing public bathhouses in the same way. What is even more shocking is that the urine concentration in the bathhouse is more than three times that of the swimming pool! This has to make people worry about whether it will do harm to people's health, but it seems to be a difficult problem to solve, because even the top swimming pool, no matter how perfect the disinfection measures, can't avoid this kind of thing. Moreover, according to news reports, even michael phelps, a famous athlete and Olympic gold medalist, admitted to urinating in the swimming pool. Researchers in Canada even said that one in five swimmers admitted that they urinated in the swimming pool at least once.

Finally, I suggest that if conditions and time permit, everyone should try to go swimming in the morning or in the morning, because the water quality in the morning is usually cleaner. Rinse with clear water immediately after swimming to keep your skin clean.
