Nonvolatile, semivolatile, or volatile: Redefining volatile for volatile organic compounds

Journal of the Air & Waste Management Association, 2014
Although widely used in air quality regulatory frameworks, the term "volatile organic compound" (VOC) is poorly defined. Numerous standardized tests are currently used in regulations to determine VOC content (and thus volatility), but in many cases the tests do not agree with each other, nor do they always accurately represent actual evaporation rates ...

Partitioning of Volatile Compounds

2014
Volatilization (also referred to as vaporization or evaporation) is the conversion of a chemical from the solid or liquid phase to a gas or vapor phase. The partitioning of a volatile compound in the subsurface environment comprises two distinct patterns: volatilization of contaminant molecules (from the liquid, solid, or adsorbed phase) and dispersion

Plant Volatile Compounds in Growth

2017
Plants synthesise volatile organic compounds (VOCs) in various tissues against stresses regarding herbivores, plant viruses, pathogens, temperature, humidity, light ozone, food usability, etc., and for physiologic processes such as plant development, seed formation and germination, pollination and fruit ripening.

Volatile Compounds in Strawberry Jam: Influence of Cooking on Volatiles

Journal of Food Science, 1991
ABSTRACTVolatile constituents of strawberry jam were identified and their olfactive impact estimated by HRGC effluent sniffing. Amounts of volatiles in jam were only slightly affected by addition of sugar, but were closely related to design of the cooker and to the pressure used. Losses by evaporation during cooking were studied.

Soil volatile fungistasis and volatile fungistatic compounds

Soil Biology and Biochemistry, 2004
Abstract Fungistasis is a widespread phenomenon that can be mediated by soil microorganisms and volatile organic compounds (VOCs). The relationship between soil microorganisms and VOCs is still unclear, however, and many fungistatic compounds remain to be identified.

Volatile compounds of commercial Milano salami

Meat Science, 1999
The relationship between extracted volatiles of Milano salami, one of the main dry-cured sausages produced in Italy, and their olfactory properties was studied. Volatile compounds were extracted by a purge-and-trap method, quantified using a flame ionisation detector and identified by mass spectrometry.

Catalytic combustion of volatile organic compounds

Journal of Hazardous Materials, 2004
Despite the success of adsorption and thermal incineration of (C)VOC emissions, there is still a need for research on techniques which are both economically more favorable and actually destroy the pollutants rather than merely remove them for recycling elsewhere in the biosphere.

changes in volatile compounds

2013
Wines from Grape Dehydration is the first of its kind in the field of grape dehydration - the controlled drying process which produces a special group of wines. These types of wine are the most ancient, made in the Mediterranean basin, and are even described in Herodotus.
