It’s recently been reported that scientists have managed to create a test to measure how much urine is in a swimming pool. It seems that peeing in the pool has become commonplace, and even high-profile swimmers have admitted to doing it during rigorous training sessions, arguing that the chlorine “kills itâ€. Not only is this untrue, but the chemical reaction that occurs between your pee and the chlorine creates a chemical that has been linked to asthma and other respiratory issues.
Nitrogen trichloride, also known as trichloramine, is made when the urea in your pee reacts with chlorine – the disinfectant widely used in swimming pool water. Nitrogen trichloride is largely made by accident in pools these days, but this compound was originally made for interest in 1812 by Pierre Louis DuLong.
