Every time I swim, I wonder how much urine is in the pool.
.
.
? Now this terrible question has been answered.
.
.
A foreign science blogger named Mark Rober found a laboratory in Canada and was determined to find out how much urine was in the pool.
.
.
Mark was in the private pool and the public one.
The pool and hot water pool of the swimming pool were sampled 4 times and sent directly to the laboratory for testing
.
At the same time, the water from the water source is used as the control group and cannot be neglected
.
Testing was performed by Lindsay Blacekstock, an expert at a Canadian laboratory
.
Lindsay said: "There is very strong evidence that people actually pee in the pool, and this test will use a new way to monitor the level of urine without using real urine
.
" - Calculate the urine content from the artificial sweetener content detected in the sample
.
Because artificial sweeteners don't come from anywhere other than human urine, accuracy can be guaranteed
.
If you can detect artificial sweeteners in swimming pools and know how much they average in each person's urine, you can estimate how much urine is in the pool
.
In fact, you can also get the result by measuring the content of urea in the pool, but urea can also come from human sweat, and sweat is not uncommon in swimming pools, so you can't tell whether the urea in the swimming pool comes from urine
.
The scientific name of artificial sweetener is "potassium acetyl sulfonate".
As a commonly used food sweetener, basically all packaged foods and beverages contain this food additive
.
Mark also collected samples at the water source as a control group, because sometimes trace amounts of sweetener ingredients may also come from the water source
.
If so, exclude it from the results
.
Before the experimental results came out, Mark also learned a big "secret"! It takes about 1 hour for the mass spectrometer to detect the result, and while Mark waits, Lindsay also tells him an amazing fact.
.
.
Chlorine in the pool can be disinfected because it kills harmful bacteria, viruses and microorganisms.
.
.
But, There is also a big downside! The chlorine used for disinfection is combined with the urea in the swimming pool to react to form "trichloramine", so you may smell that smell as soon as you enter the indoor swimming pool.
It is actually the smell of trichloramine, which is the reaction between urine and chlorine.
The smell is not just the smell of disinfectant
.
To test this claim, Mark tested it himself
.
He prepared two buckets of pure water of about 18 liters each, and then added chlorine for disinfection four times higher than the standard concentration, and then added a little urine into one of the buckets
.
After standing for 3 days, it's time to test the truth
.
Bucket A still smells of water even with 4 times the concentration of disinfectant chlorine added, while bucket B (with urine added) smells like a swimming pool
.
The smell that fills the air of resort pools and water parks all summer is due to.
.
.
piss! Sometimes after swimming, you will find that your eyes are red and swollen.
In fact, it is because of the "trichloramine" produced by the reaction between urine in the swimming pool and disinfecting chlorine
.
Lindsay has sampled 20 public swimming pools and 10 public hot springs.
The concentration of sweetener in the public pool was 470 ng/L, while the concentration of sweetener in the public hot spring (hot pool) was 2247 ng/L.
.
What was the result of the samples collected by Mark? The sweetener concentration in his own swimming pool was 69 micrograms per liter, which was much lower than average, but still equates to almost 3.
7 liters of urine in it
.
The sweetener concentration in Mark's private hot tub was slightly higher at 103 ng/L
.
In another set of samples taken by Mark in a public swimming pool, the sweetener levels in the pool and hot tub were 27 ng/L and 335 ng/L, respectively
.
After consulting experts in public hot water pools, Mark also said that there is a formula that can estimate how much urine a public pool may contain from the number of people
.
If taking the average: the number of people in the pool × 1.
2 = urine volume (gallons) if you feel more likely to urinate: the number of swimmers × 2 = the volume of urine (gallons) if you are more disciplined: the number of swimmers × 0.
5 = the volume of urine (gallons) if you take the average If the concentration is used to calculate the "Olympic standard swimming pool", there will be more than 491 liters of urine.

Flying fish" Phelps has admitted that he always urinates in the pool, and he also said that his friends do the same Even though it is said that normal urine is sterile, because urine generally does not contain any bacteria and microorganisms, but when you think of urine in the swimming pool and you swim and swim in it, you will still find it difficult to accept.
.
.
So everyone , don't pee in the pool.
.
.
Besides, let's take a bath after swimming! Suddenly I regret it, as if I know too much.
