Well, they are not true. There is no such chemical. But what is true, is that people pee in the water. The average person will leave behind about 50 Ml, which doesn’t sound too appetizing when we consider that every time you swallow a bit of pool water you are dosing yourself with some pee from all the other people in the pool.</p> Mon, 27 Mar 2017 18:38:29 +0000 Joe Schwarcz 2372 at /oss
