Prescription, over-the-counter, food additives, etc. All present in human waste.
Yes ... and whether you dump on land through normal sewage treatment systems, or at sea, most of this chemical crap finds its way into our ecosystems. As you know, our sanitation systems do not process much of this chemistry. It gets into the environment either way. So your only answer Minn (if this is your principle concern) is stop your intake of these chemicals, which will be hard to do if you're eating here in North American. Or you can stop excreting
Uric acid is simply in urine, I only wonder why people seem to consider urine more acceptable to put in the water than #2. I don't object to either, in the right circumstances, to be clear.
B/c urine does not carry the same load of pathogens (bacteria, viruses and parasites) that is commonly found in human feces. Although this varies from human to human, urine is ~95% water, with the remaining constituents being urea, and various salts (chloride, sodium, potassium). There is usually a trace amount of other inorganic and organic compounds. This is why drinking urine-contaminated water will rarely cause any harm. Doing the same with water contaminated with human feces produces a high risk of infection.
As has often been said on this thread, dilution is the solution to pollution
. This is why it is acceptable to dump your shyt while offshore. The 3-mile limit is purely arbitrary, much like voting at 18. but it's seems to be a good safe number.
