• When You Pee In The Pool, What Will Happen?

    By -

    Peeing in the pool: gross, sure, but no real harm done? Think again. Researchers recently studied what happens when urine meets water containing chlorine and other chemicals—and they found that two potentially dangerous chemical byproducts are formed.

    One in five Americans admit they have peed in a pool, and among Olympic swimmers, the practice is so widespread that a former US National team member said nearly 100 percent of competitive swimmers pee in the pool… regularly.

    Swimming in a urine-contaminated pool is certainly not the most pleasant thought, but is it really so bad?

    Olympic swimmer Michael Phelps doesn't think so, and famously said that “chlorine kills it [urine],” making peeing in the pool a non-issue. But it's not the urine itself that you need to worry about.

    Urine is virtually sterile when it leaves your body, so it doesn't pose the risk of causing illness the way fecal matter in a pool does. In fact, urine is a valuable source of nutrients that is now being used as an effective and natural fertilizer.

    So it's not the urine that is the problem… it's what happens when urine mixes with pool chemicals, including chlorine, that is catching researchers' attention.

    Peeing in the Pool Creates a Chemical Warfare Agent

    Highly toxic disinfection byproducts (DBPs) form from reactions between pool disinfectants and organic matter, including hair, skin, sweat, dirt and… urine. In a new study, researchers mixed uric acid from human urine with chlorine and found it creates two DBPs: cyanogen chloride (CNCl) and trichloramine (NCl3).

    The former, CNCI, is classified as a chemical warfare agent and is a known toxicant to your lungs, heart, and central nervous system. NCl3 is linked to lung damage.

    As for how dangerous this is, practically speaking, the researchers found that, in a worst-case scenario, urine in a pool might lead to about 30 parts per billion (ppb) of cyanogen chloride, which is well below the 70 ppb used as the maximum cyanogen concentration allowed in drinking water, according to the World Health Organization (WHO).

    Cyanogen chloride leads to coma, convulsions and death only at much higher levels (about 2,500 ppb), an amount that would be difficult, and probably impossible, to generate in a typical swimming pool from urination alone. This doesn't mean that smaller doses are “safe,” however, as DBPs have been linked to serious health problems at levels found in swimming pools.

    According to the study researchers, since urinating in a pool introduces uric acid that will lead to the formation of a poison when it interacts with chlorine, it should be avoided:

    ” …uric acid chlorination may account for a large fraction of CNCl formation in swimming pools. Moreover, given that uric acid introduction to pools is attributable to urination, a voluntary action for most swimmers, these findings indicate important benefits to pool water and air chemistry that could result from improved hygiene habits on the part of swimmers.”
