Besides, can you get sick from urine fumes?
The sharp smell of pet accidents, particularly pet urine, is indeed an irritant to the lungs. Inhalation of even low concentrations (50ppm - OSHA's exposure threshold limit) can cause rapid eye and skin irritation. Asthma (or worsening of asthma symptoms).
Beside above, how toxic is human urine? Urine is normally sterile when produced in the kidney and stored in the bladder, but is likely to become non-sterile as it leaves the body. Urine is non-toxic, although it contains urea and other substances which can be toxic if they are not excreted and reach high concentrations in the body.
In this regard, is it harmful to smell human urine?
Urine does not usually have a strong odor to it. However, occasionally, it will have a pungent smell of ammonia. One explanation for an ammonia odor is high amounts of waste in the urine. But certain foods, dehydration, and infections are also possible.
Why does human urine smell?
Causes. Urine consists mainly of water. It's the amount and concentration of various waste products excreted by the kidneys that causes urine odor. If urine becomes highly concentrated — a high level of waste products with little water — your urine may have a strong ammonia odor.
