This is probably the question you want an answer to those who like to swim: how much do the urine in the pool and how it affects your health? 

A team of academic try to answer it by doing research. They took more than 250 water samples from 31 pools and hot spring baths in Canada. The results were quite surprising.

In the swimming pool which is roughly three times the size of an Olympic-sized pool (containing 833,000 liters of water), there are 75 liters of urine. While on a smaller pool has a 30 liter. For information, Olympic-size pool is 50 meters long, 25 meters wide, and a depth of at least 1.5 meters.

The study was conducted in two cities in Canada, but the habit of peeing in the pool seems to have occurred around the world. 

'Although there are no people who claimed to have peed in the pool, but it was clear no one has done,' said Lindsay Blackstock PhD students analytical and field studies of environmental toxicology from the University of Alberta, who conducted this research.No doubt there are some people who recognize the benefits of drinking urine because it is sterile, but drink the pool water containing urine is not an idea that can be replicated. 


This is because there is a mixture of harmful substances in the pool that could potentially trigger asthma and eye irritation
The research team seek out traces of urine in the pool to look for acesulfame-K, the artificial sweetener commonly found in processed foods and beverages. The substance is found in urine because it discarded the body after ingestion. 

Turns ACE appears in all the samples studied so that the researchers could estimate roughly how much urine contained in the pool.
