Halogen: One of the chemical elements chlorine, bromine, or iodine.
Halogenated hydrocarbons
organic compounds containing carbon, hydrogen and halogen atoms (fluorine, chlorine, bromine and iodine); implicated in stratospheric ozone loss ...
Halogen: A type of incandescent lamp with higher energy-efficiency that standard ones.
Halogens
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.
halogens = the elements in the seventh period in the periodic table (fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At)

Halogens are the highly reactive elements fluorine, chlorine, bromine, iodine and astatine.
Halogen
Any of a group of five chemically-related, nonmetallic elements that includes bromine, fluorine, chlorine, iodine, and astatine. Can combine with metals to form salts or substitute for hydrogen in many organic compounds.
halogenated organic chemicals formed when water is disinfected.
dispersion
the movement and spreading of contaminants out and down in an aquifer.
Some of these categories are solids, sulfur compounds, volatile organic chemicals, particulate matter, nitrogen compounds, oxygen compounds, halogen compounds, radioactive compounds and odors.

Electron Capture Detector - One of the most sensitive gas chromatographic detector for halogen-containing compounds like chlorofluorocarbons. Here's an animation.
Disinfection byproducts: Halogenated organic chemicals formed when water is disinfected.
Dispersion: The movement and spreading of contaminants out and down in an aquifer.
chlorine - a highly reactive halogen element, used most often in the form of a pungent gas to disinfect drinking water.
Halons: Chemical compounds developed from hydrocarbons by replacing atoms of hydrogen with atoms of halogens, such as fluorine, chlorine, or bromine. CFCs are halons (see above). Halons are widely used as fire extinguishing agents.
Common greenhouse gases include water vapor, carbon dioxide (CO2), methane (CH4), nitrogen oxides (NOx), ozone (O3), chlorofluorocarbons (CFCs), halogenated fluorocarbons (HCFCs), perfluorinated carbons (PFCs), ...
Trihalomethanes. Toxic chemical substances that consist of a methane molecule and one of the halogen elements fluorine, bromine, chlorine and iodine attached to three positions of the molecule. They usually have carcinogenic properties.
precursor, THM Natural organic compounds found in all surface and groundwaters. These compounds may react with halogens (such as chlorine) to form trihalomethanes (THMs); precursors must be present in order for THMs to form.
These gases occur naturally, but large amounts emitted by human activities are adding to the climate crisis. Greenhouse gases include water vapor, carbon dioxide, methane, nitrous oxide, halogenated fluorocarbons, ozone, ...
Air pollutants are often grouped in categories for ease in classification. Some of these categories are solids, sulfur compounds, volatile organic compounds, particulate matter, nitrogen compounds, oxygen compounds, halogen compounds, ...
