Urine is primarily in lay man's term 95% water and 5% urea. When we flush with fresh water in urinals, it hydrolyses the urea in urine. Hydrolysis of urea present in human urine generates odor in urinals (Udert et al., 2003a). The enzyme urease hydrolyses urea into ammonia and carbamate.
The only way to remove the odor is to keep the urinal clean. Air fresheners don't stand much of a chance against urine. Don't forget to check the drains. Gunk in pipes can hold the urine smell, so use a foaming drain cleaner or rinse drains with vinegar and water to help eliminate odors.
Results of the present one month long study showed that many male and female participants were aware of difference in smell of urine of either sex. Those who correctly identified urine samples reported the smell of male as racy or pungent and that of female as piquant or poignant.
Uric acid comes from men who urinate on the walls, floors, their shoes or any other surface. This causes a huge amount of bacterial build-up and this produces the odour. If this is cleaned on a regular basis by a toilet hire cleaning service, then build-up won't occur and the toilets will be easier to clean.
Fish Odor Syndrome
Also called trimethylaminuria, this genetic condition can give your pee a fishy smell. It happens when your body can't break down trimethylamine. You end up getting rid of the compound through your pee, sweat, breath, and other fluids. It doesn't mean you're unhealthy.
Certain foods, including asparagus and fish, can make the urine smell. If foods are responsible, the smell should go away after a few hours. Fishy-smelling urine may be the first indication of a mild or severe health problem.
Urine may smell sweet if it contains extra glucose, which is a type of sugar. Diabetes is a common causes of this, but the smell of someone's urine can also change for other reasons. Urine can reveal a lot about someone's health.
There are apparently two reasons for the higher level of germs in the women's room. First, women tend to bring children into the bathroom with them, and children tend to bring in germs. Second, women's restrooms just get more traffic than men's rooms. Women use the bathroom more often and stay longer.
Clean More Thoroughly
An increased cleaning schedule, or more thorough cleaning will almost certainly reduce the smells coming from the toilet. Bleach and other high quality cleaning products will reduce the smells for a longer time. Further odour neutralisers can also prevent bathroom sink smells.
Simply mix equal parts of water and vinegar in a spray bottle and spritz it on any areas that smell like urine. Then, let it sit for a few minutes before wiping it away. Another popular urine odor removal method is using baking soda. To do this, sprinkle a thick layer of baking soda over the entire bathroom floor.
We have shown that female sexual attraction to spend time near male urine scent is an inherent response to a single male-specific protein pheromone, darcin, detected through physical contact.
Trimethylaminuria. In this condition, your body can't break down a compound called trimethylamine. This chemical on its own smells like rotten eggs, rotting fish, or garbage. As trimethylamine collects in your body, your sweat, breath, and urine will smell rotten or fishy.
Pheromones in humans may be present in bodily secretions such as urine, semen or vaginal secretions, breast milk and potentially also saliva and breath, yet most attention thus far has been directed toward axillary sweat.
For the most part, the urine of a healthy person is sanitary. However, over time, it is the moist atmosphere of a conventional flush urinal that can foster the growth of germs and bacteria in the urine. But because waterless urinals remain dry, they are hostile environments to bacteria and viruses.
Empty the urinal into the toilet. Rinse and wash the urinal using a disinfectant diluted with water. Dry the urinal or let it air-dry.
We recommend that these are set to actuate a flush within 20 minutes of a urinal being used and every 12 hours when they have not been used. The reason for the latter, often referred to as a "janitorial" or "hygiene" flush, is to make sure there is always enough water in the traps to preserve the water seal.
The majority of the odor is actually created by odor causing bacteria that use urine as a food source. The more bacteria that are allowed to grow the stronger the odor. The odor causing bacteria can penetrate porous surfaces, grout, and even etched porcelain causing odor issues in restrooms if not maintained properly.
Odors in your bathroom are typically due to human waste or moisture. When either of these odor-inducers build up anywhere in your bathroom, it can create a smell that permeates the entire area. Some common hiding places for odor include: Mold and mildew on baseboards, drains and vents.
Men can smell when a woman is sexually aroused
University of Kent research suggests that men can distinguish between the scents of sexually aroused and non-aroused women.
In studies conducted by eminent flatulence researcher Michael Levitt, women's farts consistently sported significantly greater concentrations of hydrogen sulfide. Odor judges have confirmed that -- at similar volumes -- this translates to a noticeably worse odor compared to men's farts.
The bathroom is a private sanctuary—a place with a locked door where trespassing is typically frowned upon—and men are more comfortable using it to their advantage in times of (emotional) need. In other words, the explanation for this phenomenon is psychological, after all.
When your body can't get energy from glucose, it burns fat in its place. The fat-burning process creates a buildup of acids in your blood called ketones, which leads to DKA if untreated. Fruity-smelling breath is a sign of high levels of ketones in someone who already has diabetes.
When a person eats a lot of protein instead of carbohydrates, their body uses protein and stored fat for energy instead of using carbohydrates as it would usually do. As a result, the ketone level in the blood will rise. When these ketones leave the body in the urine, the urine may smell sweet or similar to popcorn.
Sweet-smelling urine may be a sign of uncontrolled diabetes or a rare disease of metabolism. Liver disease and certain metabolic disorders may cause musty-smelling urine.
