Organic compounds that evaporate readily into the atmosphere at normal temperatures. VOCs contribute significantly to photochemical smog production and certain health problems. See non-methane volatile organic compounds.

Volatile (VOCs) are organic chemical compounds that have a high vapor pressure and low water solubility. Many VOCs are human-made chemicals that are used and produced in the manufacture of paints, pharmaceuticals, and refrigerants.

organic compounds
Complex molecules organized around skeletons of carbon atoms arranged in rings or chains; includes biomolecules, molecules synthesized by living organisms.

: A large group of chemical compounds containing mainly carbon, hydrogen, nitrogen, and oxygen. All living organisms are made up of .

Organic compounds formed by combustion. Usually generated in small amounts and sometimes toxic, PICs are heat-altered versions of the original material fed into the incinerator (e.g., charcoal is a P.I.C. from burning wood).

made up of atoms of carbon, chlorine, and fluorine. An example is Freon-12 (CCl2F2), used as a refrigerant in refrigerators and air conditioners and in making plastics such as Styrofoam.

Organic compounds that volatilise slowly at standard temperature (20 degrees C and 1 atm pressure).
Senescence ...

whose carbon chain molecules contain the C=O (carbonyl) functional group at the end of a carbon chain (aldehydes), with one or more hydrogen atoms substituted by halogens (chlorine, bromine, fluorine, and/or iodine).

Organic compounds that have the ability to draw ion from their water solutions into soluble complexes.
Chemical Oxygen Demand (COD) ...

that have a relatively neutral pH (are neither acid nor base), complex structure and, due to their carbon bases, are easily absorbed into the environment. Naphthalene, pyrene and trichlorobenzene are examples of neutrals.

Volatile Organic Compounds (VOCs): VOCs are manufactured as secondary petrochemicals. They include light alcohol's, acetone, trichloroethylene, perchloroethylene, dichloroethylene, benzene, vinyl chloride, toluene and methylene chloride.

Thiols which contain the "-SH" functional group. Also called mercaptans.

Total dissolved solids (TDS) is the amount of dissolved matter in the water.

Phenols: Organic compounds that are byproducts of petroleum refining, tanning, and textile, dye, and resin manufacturing. Low concentrations cause taste and odor problems in water; higher concentrations can kill aquatic life and humans.

Volatile (VOC) - that evaporate at room temperatures and are often hazardous to human health, causing poor indoor air quality. Sources of VOC's include solvents and paints.

Volatile organic compounds (VOCs)
substances such as solvents that are liquid at room temperature, but vaporise significantly and take part in the generation of ozone pollution in the lower atmosphere ...

Volatile Any compound of carbon, excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates, and ammonium carbonate, that participates in reactions of radiant energy, especially light, ...

Volatile Organic Compounds (VOC) (D):
A VOC is any organic compound which participates in atmospheric photochemical reactions; a precursor to ground-level ozone formation.

Volatile (VOCs)
that evaporate readily into the air. VOCs include substances such as benzene, toluene, methylene chloride, and methyl chloroform.

Volatile Organic Compounds (VOCs): Compounds that evaporate from the many housekeeping, maintenance, and building products made with organic chemicals. These compounds are released from products that are being used and that are in storage.

Volatile (VOCs)
Organic chemicals all contain the element carbon (C); organic chemicals are the basic chemicals found in living things and in products derived from living things, such as coal, ...

Volatile Organic Compounds (VOCs)
Pollutants that can irritate the respiratory tract irritation and cause illness. Some VOCs (e.g. benzene) can cause cancer.

Volatile (VOCs)
Substances containing carbon and different proportions of other elements such as hydrogen, oxygen, fluorine, chlorine, bromine, sulfur, or nitrogen; these substances easily become vapors or gases.

Volatile organic compounds (VOCs) are carbon compounds that participate in atmospheric photochemical reactions (excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides and carbonates, and ammonium carbonate).

Semivolatile Organic Compounds: Organic compounds that volatilize slowly at standard temperature (20 degrees C and 1 atm pressure).

Hydrocarbon: that are built of carbon and hydrogen atoms and are often used in petroleum industries.

chlororganic Organic compounds combined with chlorine. These compounds generally originate from, or associated with, life processes such as those of algae in water.

Aerobic Treatment Process by which microbes decompose complex in the presence of oxygen and use the liberated energy for reproduction and growth. Aerosol Suspended droplets of liquid or fine solid particles in air.

Most people use the terms "hydrocarbon" and "volatile organic compounds" (or VOCs) to mean the same thing.

[12] secondary production Energy in an ecosystem that is derived from the consumption of produced by other organisms. Compare primary production.

Chlorofluorocarbons (CFCs) Organic compounds made up of atoms of carbon, chlorine, and fluorine. An example is CFC-12 (CCl2F2), used as a refrigerant in refrigerators and air conditioners and as a foam blowing agent.

Low VOC Materials - VOC’s, or Volatile , are chemicals which evaporate into the air during the curing or, in some cases, throughout the life of the material.

Mercury exists in three forms: as pure metallic mercury; in inorganic compounds such as mercuric chloride; and in organic compounds such as methylmercury, which is the most toxic.

VOC Paints and Products: Volatile (VOC) are found in many paints and other products. VOCs are emitted as gases from certain room temperature solids and liquids.

The top layer removes organic compounds which could include dangerous disinfection by-products as well as those with taste and odor. The space between sand particles is larger than the smallest suspended particles, so simple filtration is not enough.

trophogenic zone a region in a body of water where synthesis of is predominant; usually refers to the photosynthetic region ...

Phytoalexins Complex organic compounds produced by plants in response to infection and that are inhibitors of further growth by the pathogen. Phytophagous Feeding on plant material.

Fluorocarbons (FCs): Any of a number of analogous to hydrocarbons in which one or more hydrogen atoms are replaced by fluorine.
