The plastics, polymer and rubbers used to insulate appliances, fixtures and electrical outlets can emit a fishy smell when they heat up. If your house suddenly smells like low tide, start sniffing ...
Made up of olfactory receptors and glands, the epithelium is used as a tool to smell others' body odour and pheromones. [10] Chemicals that produce odour pass through the olfactory epithelium to the olfactory bulbs , which contain biological receptors that detect the chemicals, and respond with an electrical signal transmitted to the brain by ...
Body Odor and Disease. In mammals, body odor can also be used as a symptom of disease. One's body odor is completely unique to themselves, similar to a fingerprint, and can change due to sexual life, genetics, age and diet. Body odor, however, can be used as an indication for disease.
Odorants are small molecules present in the environment that bind receptors on the surface of cells called olfactory receptor neurons (ORNs). [3] ORNs are present in the olfactory epithelium which lines the nasal cavity and are able to signal due to an internal balance of signal molecules which vary in concentration depending on the presence or absence an odorant.
Other than the obvious (a.k.a.: rotten food), issues like mold, spilled food particles, a dirty drip pan, and more all contribute to foul odors in this appliance.
Each fixture usually has a characteristic means of connection. Normal plumbing practice is to install a valve on each water supply line before the fixture, and this is most commonly termed a stop or "service valve". The water supply to some fixtures is cold water only (such as water closets and urinals). Most fixtures also have a hot water supply.
Thioacetone has an intensely foul odor. Like many low molecular weight organosulfur compounds, the smell is potent and can be detected even when highly diluted. [5] In 1889, an attempt to distill the chemical in the German city of Freiburg was followed by cases of vomiting, nausea, and unconsciousness in an area with a radius of 0.75 kilometres (0.47 mi) around the laboratory due to the smell.
