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.
Chlorinated Hydrocarbons: These include a class of persistent, broad-spectrum insecticides that linger in the environment and accumulate in the food chain.
Hydrocarbons - Chemicals containing only carbon and hydrogen. These are of prime economic importance because they encompass the constituents of the major fossil fuels, petroleum and natural gas, as well as anthropogenically produced plastics, ...
Hydrocarbons
Chemicals made up of carbon and hydrogen that are found in raw materials such as petroleum, coal and natural gas, and derived products such as plastics

Hydrocarbons (HC): Chemical compounds made up entirely of carbon and hydrogen.
Hypersensitivity: The immune system's exaggerated response to an allergen.
hydrocarbons
Any of a vast family of compounds originating in materials containing carbon and hydrogen in various combinations.
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.
Hydrocarbons
Hydrocarbons are produced when petrol is not fully burnt. They are one of the causes of modern-day smog.
Hydrocarbons that contain chlorine. These include a class of persistent insecticides that accumulate in the aquatic food chain. Among them are DDT, aldrin, dieldrin, heptachlor, chlordane, lindane, endrin, Mirex, hexachloride, and toxaphene.
Chlorinated hydrocarbons
organic compounds containing the elements carbon, hydrogen and chlorine, implicated in low level ozone production and high level ozone destruction ...
Chlorinated hydrocarbons: Hydrocarbons that contain chlorine. These include a class of persistent insecticides that accumulate in the aquatic food chain.
Total Petroleum Hydrocarbons (TPH): A measure of the mass or concentration of all the petroleum constituents present in a given amount of air, soil, or water.
Total Petroleum Hydrocarbons (TPH): Measure of the concentration or mass of petroleum hydrocarbon constituents present in a given amount of soil or water.
These fuels are made of hydrogen and carbon (hydrocarbons). greenhouse gas Gases such as carbon dioxide and methane that trap heat in the atmosphere.
PAH- Polynuclear Aromatic Hydrocarbons
PAl- Performance Audit Inspection (CWA); Pure Active Ingredient compound
PAM- Pesticide Analytical Manual
PAMS- Photochemical Assessment Monitoring Stations
PAT- Permit Assistance Team (RCRA) ...
PVC, chloroform, certain pesticides and insulators are made up of chlorinated hydrocarbons. Chlorine A chemical widely-used in water purification, disinfectants, bleach and mustard gas.
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.
The various oxides of nitrogen can also react with hydrocarbons in the atmosphere to contribute to photochemical smog. NOx can also affect ecologically sensitive sites through deposition, causing acidification and eutrophication. In The U.S.
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.
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.
Natural Gas - Natural gas is a mixture of hydrocarbons (mainly methane (CH4)) and is produced either from gas wells or in conjunction with crude oil production.
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.
Carbon chain the atomic structure of hydrocarbons in which a series of carbon atoms, saturated by hydrogen atoms, form a chain. Volatile oils have shorter chains. Fats have longer chain lengths, and waxes have extremely long chains.
...
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.
