Analytical results identified 29 compounds, including ammonia, amines, acetic acid, and multiple volatile organic compounds (VOCs) (hydrocarbons, ketones, esters, terpenes and S-compounds) in the odor from food waste composting plants.
To tackle both challenges, the work described in this paper focuses on the development of a new hybrid method which couples multi-module method with artificial neural networks (ANNs) for the optimization optimized multi-module ANN classifier (OMAC) to enhance the correct detection rate for multiple volatile organic compounds (VOCs).
The murky depths of the canal conceal the remnants of its industrial past: cement, oil, mercury, lead, multiple volatile organic compounds, PCBs, coal tar, and other contaminants.
Examples include the use of carbon nanotubes to detect molecular gases in the environment (Lim et al. 2012), molecular imprinted fibers to detect hydrocarbon exposures (Chen et al. 2012), and the development of nanoporous pigments to detect multiple volatile toxic compounds (Lin et al. 2011).
Phenylpropenes, a large group of plant volatile compounds that serve in multiple roles in defense and pollinator attraction, contain a propenyl side chain.
The multiple secondary metabolites in Citrus, including flavonoids, alkaloids, coumarins, limonoids, carotenoids, phenolic acids and volatile compounds, provide a rational basis for various biological activities.
Similarly, in the presence of multiple odorous objects, the olfactory system identifies the objects by their unique combinations of volatile compounds and, at the same time, segregates among these objects.
Chocolate has many volatile compounds.
Mammalian urine contains many different volatile compounds.
In most spills, the volatile compounds evaporate.
