The human body doesn't break down aspartame potassium, so it's excreted in urine but remains detectable in bodies of water, even at varying pH levels and temperatures, according to Environmental Science & Technology Letters, a respected "pee-riodical". Americans consume about 17 million metric tons of artificial sweeteners per year.
And while it's gross to think about, we know what you're thinking: maybe it's OK because urine is considered sterile and wouldn't the chlorine kill anything harmful, anyway?
CBS News reports an estimated 75 liters of urine is present in a moderately sized swimming pool just one-third the size of an Olympic pool. "The benefits of keeping active through swimming outweigh the potential risks we use as rationale for the study", said Blackstock.
If you've ever been to a public swimming pool, you're familiar with the stinging sensation of chlorine hitting your nostrils when you approach the water. Scientists in Canada have conducted a study aimed at attaching some figures to this unsavory conundrum, and while the results do resemble drop-in-the-ocean-type proportions, they'll still be enough to make you a little more suspicious of those swimming nearby.
On average, there were 8 gallons of urine in a 110,000-gallon pool and 18.5 gallons of urine in a 220,000-gallon pool. In one hotel hot tub, a sample showed a concentration of ACE three times higher than the highest level found in a swimming pool.
"These compounds can react with disinfectants in swimming pools to form disinfection byproducts".
Michael Phelps said everyone does it, so it should come as no surprise that researchers found pools contain pee.
Blackstock also emphasized that people should not be afraid of the pee that's nearly certainly in your hotel swimming pool or hot tub.
Swimming pool is a great place to cool down. Exposure to the DBPs, especially at indoor pools and hot tubs, can lead to problems such as eye and respiratory irritation and even occupational asthma.
RG: What do you recommend for people who regularly swim regularly to avoid health issues?
If you ever found yourself wondering about how much urine is there in a public pool, then you will be absolutely thrilled to find out that a team of Canadian researchers asked the same question and actually got their answer.
