Researchers have found that peeing in a swimming pool has deleterious effects and the practice should stop. See a Science Daily article for details. Hat tip to Lucianne.com for the link.
Apparently the combination of pool chlorine and uric acid from urine combine to form, among other compounds, trichloramine (NCl 3) and cyanogen chloride (CNCl). Both are bad for human lungs and perhaps the heart and circulatory system too.
I am reminded of a cute sign I saw over a toilet in a cabana which gently chided "You wouldn't swim in our toilet, please don't pee in our pool."
