Human piss probably has a lot of nasty chemicals in it. Bi-sphenol A, from plastic, lead, soluable copper, mercury, di-methylsomethingorother, dioxin and at least but not last, uranium, plutonium, cesium-90 or 137. Oh, and radioactive lead 211. But that only lasts for a couple of millionths of a second. If you're standing next a particle accelerator.
