Decomposition
The breakdown of matter by bacteria and fungi, changing the chemical makeup and physical appearance of materials.
residual chlorine The amount of free and/or available chlorine remaining after a given contact time under specified conditions.
Available chlorine A measure of the amount of chlorine available in chlorinated lime, hypochlorite compounds, and other materials.
B ...
Addition of chlorine to plant effluent for disinfectant purposes after the effluent has been treated.

The term organochlorine refers to a wide range of chemicals that contain carbon, chlorine and, sometimes, several other elements.
Chlorofluorocarbons (CFCs): Stable, man-made chemical compounds containing carbon, chlorine, fluorine and sometimes hydrogen.
Compounds formed by the reaction of hypochlorous acid (or aqueous chlorine) with ammonia.
chlorination (KLOR-uh-NAY-shun).
macronutrients nutrients needed in relatively large amounts, such as phosphorus, calcium, magnesium, potassium, sulfur, nitrogen, chlorine, and sodium
macrophyte a large plant, as opposed to small and microscopic plants such as algae ...
Because they are not destroyed in the lower atmosphere, they drift into the upper atmosphere where their chlorine components destroy ozone. chloroplast An organelle in the cells of green plants.

For example, HCl and ClONO2, are reservoir species for chlorine. BrCl and BrONO2 are reservoir species for bromine (Br).
CFCs (chlorofluorocarbons): Any of the various compounds consisting of chlorine, hydrogen, fluorine, and carbon.
An almost colorless, gaseous form of oxygen with an odor similar to weak chlorine.
The family of elements that includes fluorine, chlorine, bromine and iodine. Halogens are very reactive and have many industrial uses. They are also commonly used in disinfectants and insecticides.
Chlorination: Adding chlorine to water or wastewater, generally for the purpose of disinfection, but frequently for accomplishing other biological or chemical results.
Volatile organic compounds (VOCs) - Organic chemicals containing carbon, oxygen, hydrogen, chlorine, and other atoms. Volatile chemicals produce vapors readily.
Dechlorination: Removal of chlorine from a substance.
Decomposition: The breakdown of matter by bacteria and fungi, changing the chemical makeup and physical appearance of materials.
Chlorination: addition of chlorine as a means of disinfecting drinking water or wastewater.
Co-compositing: simultaneous composting of two or more diverse waste streams.
chlorination The application of chlorine to water, generally for the purpose of disinfection.
Chloramines. A mixture of ammonia and chlorine used to disinfect water.
Closed basin. A groundwater basin whose topography and geology prevent subsurface outflow of water.
DIOXIN Chlorinated organic compound: a by-product of the paper-making process that uses chlorine as a bleaching agent. Dioxins can be released into the atmosphere through the incineration of chlorinated paper.
Chlorinated Solvent - An organic solvent containing chlorine atoms, e.g., methylene chloride and 1,1,1-trichloromethane, used in aerosol spray containers and in highway paint.
Chlorinated Solvents: Organic solvents containing chlorine atoms. Examples include methylene chloride, perchloroethylene and 1,1,1 trichloroethylene used as cleaning agents.
Chlorofluorocarbons (CFCs): Any of a number of substances consisting of chlorine, fluorine, and carbon. CFCs are used for refrigeration, foam packaging, solvents, and propellants. Visit the Cal/EPA website for more information.
Dioxins
a group of toxic organic substances, containing carbon, hydrogen, oxygen and chlorine, resistant to biodegradation, produced when organic material is incinerated at low temperatures.
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.
Ozone Depletion - Destruction of the Earth's ozone layer, which can be caused by the photolytic breakdown of certain chlorine- and/or bromine-containing compounds (e.g., chlorofluorocarbons), which catalytically decompose ozone molecules.
analyzer A device which conducts periodic or continuous measurement of some factor such as chlorine, fluoride, or turbidity. Analyzers operate by any of several methods including photocells, conductivity or complex instrumentation.
Non-toxic cleaners: Cleaning products that contain no toxic chemicals like chlorine, ammonia, butyl cellosolve and hydrochloric acid.

Halogens are the highly reactive elements fluorine, chlorine, bromine, iodine and astatine.
Micronutrients, or those required in small amounts are boron, chlorine, cobalt, copper, iron, manganese, molybdenum, silicon, sodium, vanadium, and zinc. These also must generally be obtained from the soil.
dioxin: the popular name for a family of organic compounds that bio-accumulate with toxic effect in humans and wildlife. Two of the most widely studied sources of dioxins are the making of the herbicide Agent Orange and the chlorine bleaching of ...
easily liquefied chemicals used in refrigeration, air conditioning, packaging, and insulation, or as solvents and aerosol propellants. Because CFCs are not destroyed in the lower atmosphere, they drift into the upper atmosphere, where their chlorine ...
Catalytic oxidizers can also be very effective in controlling odors. High moisture content and the presence of chlorine or sulfur compounds can adversely affect the performance of the catalytic oxidizer.
