….which is 5-10 times more than are found in saliva. Such is the result of an intensive 7 year study of human urine. Gizmodo takes up the story:

A team of 20 researchers from the University of Alberta proudly announced a commendable achievement on Thursday. Using no fewer than five different experimental methods, they’ve discovered over 3000 different chemical compounds in human urine. And it only took them seven years.

Urine analysis sounds pretty gross at first. When you really think about it, though, a better understanding of what’s in our pee could bears some pretty exciting implications in science and medicine. Consider that the standard urine tests typically check just six or seven compounds, even though urine contains traces of everything from the food you eat to the drugs you take to random bacteria floating around your body. This new comprehension of the yellow liquid could not only help researchers better understand how our bodies process waste but also enable doctors to diagnose illnesses in a quicker, less invasive manner. (Nobody likes needles.)

From a big picture point of view, the findings reveal some interesting details about how the human body works. For instance, nearly 2300 of the compounds found in the urine come from outside the human body in the form of food, drink, drugs and even cosmetics. The researchers also concluded that urine is one of the more complex fluids in the human body with five to 10 times more compounds than are found in saliva.

Not really. Analysis of bodily materials has a long history as people sought to explore nature from a chemical, or alchemical perspective.

I am reminded of the work of Brand(t) who first discovered phosphorus in urine while trying to make gold, and Boyle, who developed the first process to make it commercially, by heating urine with sand.

Brandt is immortalised in the painting “The Alchymist”

Please please do the same sort of analysis on the results of a Miller-Urey type experiment containing elements H, C, N, O, S, Si, Fe, Al, Mg, Cl, Na, P.

Possibly but not necessarily also containing other elements detected in urine (calcium, iodine, potassium, manganese, molybdenum, tin, nickel, mercury, lithium, neodymium, hafnium, chromium, cobalt, copper, fluorine, germanium, caesium, thallium, platinum, cadmium, cerium, lanthanum, gallium, arsenic, boron, gold, barium, bromine)

I would expect human urine to contain all the stable elements.

Me too, but it contained less than half of them, possibly because the others couldn’t be absorbed through the stomach and intestines.

Or maybe the kidneys.

All of the stable nuclides do make it into the blood stream, as they have all been found in human hair.
