The product obtained in this fashion is known as volatile oil of mustard. It is used principally as a flavoring agent in foods. Synthetic allyl isothiocyanate is used as an insecticide , as an anti-mold agent [ 9 ] bacteriocide , [ 10 ] and nematicide , and is used in certain cases for crop protection. [ 4 ]
An oil is any nonpolar chemical substance that is composed primarily of hydrocarbons and is hydrophobic (does not mix with water) and lipophilic (mixes with other oils). Oils are usually flammable and surface active. Most oils are unsaturated lipids that are liquid at room temperature.
Alternatively, the water (e.g. 10 to 50%) is emulsified into the fuel oil before the injection and combustion. This emulsification can either be made in-line (unstabilized) just before the injection or as a drop-in fuel with chemical additives for long-term emulsion stability (stabilized).
Indoor air pollution has been a hot topic over the past few years thanks to a growing body of research that found that different cooking tools, including gas stoves and Teflon pans, can make you sick.
Both oil and water based techniques rely on the vaporization of water to cook the food. Oil based cooking techniques have significant surface interactions that greatly affect the quality of the food they produce. These interactions stem from the polar oil molecules interacting with the surface of the food. Water based techniques have far less ...
Air pollution can cause diseases, allergies, and even death; it can also cause harm to animals and crops and damage the natural environment (for example, climate change, ozone depletion or habitat degradation) or built environment (for example, acid rain). [3] Air pollution can occur naturally or be caused by human activities. [4]
LPG burns more cleanly than higher molecular weight hydrocarbons because it releases less particulate matter. [41] As it is much less polluting than most traditional solid-fuel stoves, replacing cookstoves used in developing countries with LPG is one of the key strategies adopted to reduce household air pollution in the developing world.

[39] [40] In some towns and cities in New South Wales, wood smoke may be responsible for 60% of fine particle air pollution in the winter. [41] A year-long sampling campaign in Athens, Greece found a third (31%) of PAH urban air pollution to be caused by wood-burning, roughly as much as that of diesel and oil (33%) and gasoline (29%).
