sorption
Noncommittal term used instead of adsorption or absorption when it is difficult to discriminate experimentally between these two processes.
Sorption - A class of processes by which one material is taken up by another.
Sorption: The action of soaking up or attracting substances; process used in many pollution control systems.
sorption A surface phenomenon which may be either absorption or adsorption, or a combination of both; often used when the specific mechanism is not known.
Absorption
1) The process by which one substance is taken into the body of another substance. 2) The penetration of molecules or ions of one or more substances (gas, liquid or solid) into the interior of another substance.
adsorption
the adhesion of a substance to the surface of a solid or liquid. Adsorption is often used to extract pollutants by causing them to be attached to such adsorbents as activated carbon or silica gel.
adsorption complex
The group of substances in the soil capable of adsorbing other materials. Organic and inorganic colloidal substances form the greater part of the adsorption complex.
Absorption: The process of one substance entering into the inner structure of another.
Abrasion: The wearing away of a solid surface by friction.
Abrasive Cleaners: Products that clean through abrasive or scouring action.
Absorption (of light) A process by which light is taken-up by another material.
Absorption: When a solid takes up molecules into its structure.
Accretion: A gradual increase in land area adjacent to a river
Acid aerosol: Very small liquid or solid particles that are acidic and are small enough to become airborne.
absorption = take in and store

Absorption
The process of taking in. For a person or an animal, absorption is the process of a substance getting into the body through the eyes, skin, stomach, intestines, or lungs.
Acute
Occurring over a short time [compare with chronic].
Absorption coefficient -Ratio of the absorbed amount of a substance to the administered amount.
absorption : the penetration of atoms, ions, or molecules into the bulk mass of a substance.
Absorption
The penetration of a substance into or through another substance or medium is absorption.
Acid Rain ...
A absorption barrier
Definition (english only)
Any exposure surface that may allow diffusion of an agent into a target. Examples of absorption barriers are the skin, lung tissue, and gastrointestinal track wall.
Absorption The process of taking in, as when a sponge takes up water. Chemicals can be absorbed into the bloodstream after breathing or swallowing.
Dermal Absorption/Penetration- Process by which a chemical penetrates the skin and enters the body as an internal dose.
Dermal Exposure- Contact between a chemical and the skin.
Carbon Adsorption
A treatment system that removes contaminants from ground water or surface water by forcing it through tanks containing activated carbon treated to attract the contaminants.
Carbon Monoxide ...
Gas-Fired Absorption Chiller - Mechanical equipment that is used to generate chilled water for cooling of buildings. Conventional chillers use electricity as the energy source, whereas gas-fired absorption chillers use clean burning natural gas.
Atmospheric absorption of various wavelengths of electromagnetic radiation (measured along sea level).
Absorption Process, either chemical or physical, by which a substance or particle, gas or liquid, is drawn into the structure of another. Acid A material with pH of less than 7.0.
Measure of the sorption phenomenon, whereby a pesticide is divided between the soil and water phase; also referred to as adsorption partition coefficient.

absorption coefficient A measure of the amount of radiant energy, incident normal to a planar surface, that is absorbed per unit distance or unit mass of a substance.
adsorption the adhesion of a very thin layer of molecules to the surfaces of solids or liquids with which they come into contact.
adsorptionThe process by which chemicals are held on the surface of a mineral or soil particle.
Ion exchange An adsorption process in which one ion is exchanged for another ion of like charge. There is an equivalence of exchanged charge.
...
The effect of trapping heat by the transmission of visible solar energy, and the absorption (or reflection) of infra red heat energy. This can be done by a sheet of glass or a layer of some gases, known as greenhouse gases.
The materials can enter via inhalation, ingestion, absorption or injection.
Chlorophyll has minimal absorption in the green and yellow wavelength which is why most leaves are green. Other pigments also occur in tree leaves but normally are masked by the large amount of green chlorophyll.
Dermal - Referring to the skin. For example, dermal absorption means absorption through the skin.
Detection limit - The smallest amount of substance that a laboratory test can reliably measure in a sample of air, water, soil or other medium.
Radiation originating as the result of absorption of other radiation in matter. It may be either electromagnetic (e.g. Bremstrahlung from 32P betas passing through lead) or particulate in nature.
Shallow Dose Equivalent ...
Thermospheric temperatures increase with altitude due to absorption of highly energetic solar radiation by the small amount of residual oxygen still present. Temperatures can rise to 2,000 degrees Celsius.
Can be controlled by chemical dispersion, combustion, mechanical containment, and/or adsorption.
But when a tree is cut down or an animal dies, the absorption stops and the level of carbon-14 begins to fall as the isotope decays.
Scrubber - a device that uses a high energy liquid spray to remove aerosol and gaseous pollutants from an air stream. The gases are removed either by absorption or chemical reaction ...
Adding simulation of the ability of the environment to sink carbon dioxide suggested that rising fossil fuel emissions would decrease absorption from the atmosphere, amplifying climate warming beyond previous predictions, although "Globally, ...
A dose of one rad is equivalent to the absorption of 100 ergs (a small but measurable amount of energy) per gram of absorbing tissue. The rad has been replaced by the gray in the SI system of units (1 gray = 100 rad).
describe the slowing, modification, or diversion of the flow of water as with Detention and Retention.
(2) (Water Quality) The process of diminishing contaminant concentrations in ground water, due to filtration, biodegradation, dilution, sorption, ...
Scrubber: An air pollution control device that uses a high energy liquid spray to remove aerosol and gaseous pollutants from an air stream. The gases are removed either by absorption or chemical reaction.
Children are more susceptible to contaminants in food because they take in four times the amount of food per kilogram of body weight that adults do, are more likely to be exposed to impurities in food, and their absorption of foods is greater than is ...
Sodium adsorption ratio (SAR) - a way to measure sodium in the soil. A value of 13 or higher indicates the soil is sodic.
Stratified - formed, arranged, or laid down in layers. The term refers to geologic deposits.
