Science proves it: People pee in the pool

The amount of urine in a large swimming pool is enough to fill a dustbin

But thanks to the artificial sweeteners you eat, science knows.

Blackstock: First and foremost, we want to emphasize that the health benefits from maintaining a healthy lifestyle through swimming far exceed the potential risks associated with urine in swimming pools and hot tubs.

A scientific study of swimming pools and hot tubs in Canada has found a large pool of about 830,000 litres could contain up to 75 litres of urine. Reportedly, the artificial sweetener was found in high concentrations in every single one of the pools and hot tubs tested.

Despite that the authorities assure us that the pools are cleaned out on a regular basis and prohibiting people from urinating in public pools, we are unsure whether these summer delights are safe or not.

However, there's one surprising part of this study that demands more research immediately: The researchers report "19 percent of adults have admitted (emphasis own) to having urinated in a swimming pool at least once". According to the scientists involved in the new pee-measuring project, an average city block pool contains approximately 30 liters of urine, which is enough to fill a small trashcan.

In order to do this, we need improved understanding of pool chemistry.

As the paper points out, the level of urine is 570 times greater than that found in tap water. He said pool managers resort to adding even more chlorine to their pool, which only exacerbates the chemical byproducts.

While most people, beyond early childhood, would not admit to using their local swimming pool as a giant communal toilet, the results are not entirely surprising. They point to recent studies that have shown bodily fluids like urine and sweat can react with disinfectants in the water to form disinfection byproducts (or DBPs), compounds that may cause uncomfortable symptoms like eye irritation and respiratory problems.

The simple analysis Li and her team performed involved taking pool and hot tub samples and passing them through a high performance liquid chromatography-mass spectrometer system, one of the most common instruments for determining what chemicals are in a given thing.

Using these results, the scientists approximated the amount of human urine present in an average swimming pool.

RG: What do you recommend for people who regularly swim regularly to avoid health issues?

The simplest solution: Just don't pee in the pool.

"We recommend that all pool users should rinse off excess personal care products in the provided showers before entering public pools", she told Research Gate.
