Diesel exhaust is the exhaust gas produced by a diesel engine, plus any contained particulates. Its composition may vary with the fuel type, rate of consumption or speed of engine operation (e.g., idling or at speed or under load), and whether the engine is in an on-road vehicle, farm vehicle, locomotive, marine vessel, or stationary generator ...
Hematidrosis is a condition in which capillary blood vessels that feed the sweat glands rupture, causing them to exude blood, occurring under conditions of extreme physical or emotional stress. [4] Severe mental anxiety activates the sympathetic nervous system to invoke the fight-or-flight response to such a degree as to cause hemorrhage of the ...

"The more you idle, the more exhaust is released," she says. If your vehicle is moving every few seconds, that's not considered idling, Randhawa adds. "It's when you're at a full stop and it's ...
Smell as evidence of disease has been long used, dating back to Hippocrates around 400 years BCE. [1] It is still employed with a focus on volatile organic compounds (VOCs) found in body odor. [ 2 ] VOCs are carbon-based molecular groups having a low molecular weight, secreted during cells' metabolic processes. [ 3 ]
Phantosmia (phantom smell), also called an olfactory hallucination or a phantom odor, [1] is smelling an odor that is not actually there. This hallucination is intrinsically suspicious as the formal evaluation and detection of relatively low levels of odour particles is itself a very tricky task in air epistemology.
There is strong scientific evidence that nocebo effects can lead to (sometimes severely disabling) illness from environmental exposures that are perceived as hazardous." [ 28 ] However, there is no reliable, systematic method for establishing whether nocebo effects are responsible for individual cases of illness. [ 29 ]
But when you sneeze, you expel air and change up that flow, forcing odorous particles in your nose or throat upward to the olfactory nerve high in the nasal cavity, which transmits information ...
