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

[Kevin Chisholm]

Dear Edward

I would GUESS that if the waste products concentrations were serious 
enough, that teh urine donor would soon be dead, and unable to 
contribute much further.

Sewage from a Municipal Sewage system is much different that "home 
grown" urine and feces. For one thing, unused and out-dated medications 
are often flushed down teh toilet. For another, industrial wastes sent 
to Municipal sewers can be "endocrine disruptors." I would thus feel 
that "home collected" urine and feces would inherently have less of teh 
hazards to which you refer.

However, there are other hazards. For example, e-coli contamination of 
food crops if humanure is not applied properly. As I understand it, this 
concern is absent with urine.

Your point about getting valid data is very valid. The fact that such 
concerns can be raised suggests that data is necessary to address these 
concerns.

Our North American Culture has big hang-ups about bodily functions. I 
grow beans and apply urine as a nutritional supplement. Most people I 
talk to say "You are not going to eat the beans are you?" Yet, they see 
no problem using animal feces as fertilizer. With only urine and 
seaweed, I can grow Pole Beans 20' tall.

Best wishes,

Kevin
