[Terrapreta] Pee AKA human urine ------- endocrine disrupting chemicals, female hormones, and pharmaceuticals CONCENTRATED in urine

[Edward Someus]

Do you have info on data for specific targeted investigation of endocrine
disrupting chemicals, female hormones, and pharmaceuticals CONCENTRATED in
urine to be used in soil? 
 
 
Endocrine disrupting chemicals, female hormones, and pharmaceuticals in
urine is one of the most important problem of the municipal sewage water
treatment, and very difficult to handle it. 


These substances are in very low level in the sewage stream, difficult to
trace, but despite the small amount they are very very dangerous. So far
these elements where not a problem, because they where not traced and not
detectable, but now the chemistry is more advanced than years ago, and more
advanced chemical analytical methods are still under development. 


If endocrine disrupting chemicals, female hormones, and pharmaceuticals in
urine is a huge problem of the municipal sewage water treatment, why should
not it be a big problem for soil application at food crop production, not to
talk about several other problems with the urine use?

Except: In Sweden, a test market in the council of Tanum is recycling urine
for use as fertilizer on farms. All new homes in the area are required by
law to have special toilets that separate urine and pipe it into a holding
tank that farmers access at regular intervals. 
Experts say this is better for the environment because the special toilets
use less water. And less energy is utilized at treatment facilities. 
Most importantly, human urine has the most concentrated source of phosphorus
 which is a vital ingredient in agricultural fertilizer. Tell that to the
neighbour with the great lawn.

Received: 26 September 1994  Accepted: 23 January 1995  
Abstract  Stored human urine had pH values of 8.9 and was composed of eight
main ionic species (> 0.1 meq L–1), the cations Na, K, NH 4, Ca and the
anions, Cl, SO4, PO4 and HCO3. Nitrogen was mainly (> 90%) present as
ammoniacal N, with ammonium bicarbonate being the dominant compound. Urea
and urate decomposed during storage. 
 Heavy metal concentrations in urine samples were low compared with other
organic fertilizers, but copper, mercury, nickel and zinc were 10–500 times
higher in urine than in precipitation and surface waters. In a pot
experiment with 15N labelled human urine, higher gaseous losses and lower
crop uptake (barley) of urine N than of labelled ammonium nitrate were found

 Phosphorus present in urine was utilized at a higher rate than soluble
phosphate, showing that urine P is at least as available to crops as soluble
P fertilizers.
