Chlorinated Hydrocarbons
1. Chemicals containing only chlorine, carbon, and hydrogen. These include a class of persistent, broad-spectrum insecticides that linger in the environment and accumulate in the food chain.

Hydrocarbons: Compounds containing various combinations of hydrogen and carbon atoms. They may be emitted into the air by natural sources (e.g., trees) and as a result of fossil and vegetative fuel combustion, fuel volatilization, and solvent use.
Hydrocarbons describe a wide range of compounds that contain hydrogen and carbon molecules. Many oil, paraffins, and coal are hydrocarbons.

H hydrocarbons
Definition (english only)
Compounds of hydrogen and carbon in various combinations that are present in petroleum products and natural gas.
Hydrocarbon: Chemical compounds composed only of carbon and hydrogen.
Hydrogen Peroxide: H2O2. Hydrogen peroxide is used to increase the dissolved oxygen content of groundwater to stimulate aerobic biodegradation of organic contaminants.
Hydrocarbons
Hydrocarbons are produced when petrol is not fully burnt. They are one of the causes of modern-day smog.
Hydrocarbon a compound of hydrogen and carbon, often occurring as long atomic chains in which each carbon atom is attached to two hydrogen atoms forming a long chain. They store a great deal of energy.

These fuels are made of hydrogen and carbon (hydrocarbons). greenhouse gas Gases such as carbon dioxide and methane that trap heat in the atmosphere.
Terpenoids Aromatic hydrocarbons formed by many plants and responsible for many of the plant scents. Territoriality The establishment by an animal or animals of an area from which other individuals are partially or totally excluded.
VOCs or "volatile organic compounds" VOCs are primarily the lighter 'fractions' of oil or hydrocarbons (i.e., the parts that evaporate easily because they have a low boiling point).
Persistent Organic Pollutants (POPs) 7 include two major types: Organochlorines (OCs) as well as Polycyclic Aromatic Hydrocarbons (PAHs). Organochlorines (OCs) are almost always human-made.
Polynuclear aromatic hydrocarbons (PAHs or PNAs)
PNAs or Polynuclear Aromatic Hydrocarbons, are natural constituents of crude oil, and also may be formed when organic materials such as coal, oil, fuel, wood or even foods are not completely burned.
Methane (CH4): A hydrocarbon that is a greenhouse gas with a global warming potential most recently estimated at 23 times that of carbon dioxide (CO2).
Ozone is formed by a series of reactions involving oxygen, hydrocarbons, nitrous oxides and sunlight. Hydrocarbons and nitrous oxides are emitted from various sources with automobiles and electric generating facilities as primary contributors.
First, both charcoal and wood burn "dirty," producing not only hydrocarbons but also tiny soot particles that pollute the air and can aggravate heart and lung problems.
A colorless, odorless, flammable hydrocarbon (CH4) that is produced by the decomposition of organic matter, and other processes.
Dioxins: heterocyclic hydrocarbons that occur as toxic impurities, especially in pesticides.
Discharge: flow of surface water in a stream or the flow of ground water from a spring, ditch, or flowing artesion well.
Fossil fuels: Coal, oil, petroleum, and natural gas and other hydrocarbons are called fossil fuels because they are made of fossilized, carbon-rich plant and animal remains.
Producer gas is composed of carbon monoxide (CO) and hydrogen (H2) plus carbon dioxide (CO2) and typically a range of hydrocarbons such as methane (CH4).
alkynes The group of unsaturated hydrocarbons with a triple Carbon-Carbon bond having the general formula C(n)H(2n-2).
allegation An assertion or statement, made in a pleading, setting forth what its maker intends to prove.
Atmospheric air purified to contain less than 0.1 ppm total hydrocarbons.

toxicant whose properties are assumed to apply to an entire chemically and toxicologically related class; for example, benzo(a)pyrene data may be used as toxicologically equivalent to that for all carcinogenic polynuclear aromatic hydrocarbons.
bitumen Dark, naturally occurring solid or semisolid substances composed mainly of a mixture of hydrocarbons with little oxygen, nitrogen, or sulfur.
