Smell disorders can result in the inability to detect environmental dangers such as gas leaks, toxins, or smoke. In addition to safety, nutritional and eating habits can also be affected. There is a loss of appetite because of unpleasant flavor and fear of failing to recognize and consuming spoiled food.
A stink bomb, sometimes called a stinkpot, is a device designed to create an unpleasant smell. They range in effectiveness from being used as simple pranks [ 1 ] to military grade malodorants or riot control chemical agents .
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.
Scientists have studied the impact of plastic on the ecological environment for decades and have raised concerns about the health effects of some chemicals used in plastics.
The device combines a digital display with four small fans that direct an emitted odor to a specific spot on the screen. The fans operate at a very low speed, making it difficult for the user to perceive airflow; instead they perceive the smell as coming directly out of the screen and object displayed at that location.

In all industries, odor assessment is usually performed by human sensory analysis, by chemosensors, or by gas chromatography.The latter technique gives information about volatile organic compounds but the correlation between analytical results and mean odor perception is not direct due to potential interactions between several odorous components.
Hyperosmia is an increased olfactory acuity (heightened sense of smell), usually caused by a lower threshold for odor. [1] This perceptual disorder arises when there is an abnormally increased signal at any point between the olfactory receptors and the olfactory cortex.
