Solid human waste is collected in plastic bags and returned to the station for incineration.
Urine is collected in drums and disposed of in stations’ sewage systems, although direct disposal in tide cracks is allowed at coastal sites..
What does a 7.0 pH in urine mean?
A neutral pH is 7.0. The higher the number, the more basic (alkaline) it is. The lower the number, the more acidic your urine is. The average urine sample tests at about 6.0. If your urine sample is lower, this could indicate an environment conducive to kidney stones.

Does freezing urine affect pH?
2.2. Influence of Freezing and Storage Conditions on pH of Urine Samples. … Although the changes in pH are small, due to the added buffer, there are reproducible pH changes of about 0.05 to 0.1 pH units in the samples that were frozen on dry ice and analyzed immediately or stored thereafter in lN2.
Does your pee freeze in Antarctica?
