leachability
Noun: - The quality or state of being able to be leached: "leachability" refers to the degree to which a substance can be dissolved, extracted, or removed from a solid material (such as soil, rock, or waste) by the action of a liquid (typically water) percolating through it. It is a measure of how readily components are mobilized and carried away by a solvent.
- (The ability of these metals to dissolve and be carried by water is a concern.)
- (They measured how easily the fertilizer's components could be extracted by water.)
- (A high degree of extraction by liquid indicates potential contamination.)
"Leachability test": a standardized laboratory procedure used to assess the potential for a substance to release contaminants into the environment.
- The leachability test showed that the treated wood still released arsenic. (The test measured the wood's tendency to lose harmful chemicals when wet.)
"Leachability factor": a numerical value representing the rate or extent at which a substance is leached under specific conditions.
- The leachability factor for nitrate in sandy soil is much higher than in clay. (The number indicates how quickly nitrate is dissolved and carried away.)
Leach (verb): to remove or extract soluble substances from a solid by the action of a liquid.
- Rainwater can leach nutrients from the soil. (Water dissolves and carries away nutrients.)
Leachable (adjective): capable of being leached.
- Some pesticides are highly leachable and can contaminate water supplies. (They are easily dissolved and removed by water.)
Leaching (noun): the process by which soluble substances are dissolved and carried away by a liquid.
- The leaching of minerals from the ore is an important part of mining. (The process of extraction by liquid.)
- Extractability: the ability to be removed or drawn out.
- Solubility: the ability to dissolve in a liquid, though "leachability" specifically implies transport through a solid matrix.
- Mobility: the tendency of a substance to move through a medium, often used in environmental chemistry.
- There are no common idioms using "leachability," as it is a technical term. However, the concept is related to the phrase "leach out" (as a verb phrase), meaning to be gradually removed by liquid.
- The salt leached out of the soil after heavy rain. (The salt was dissolved and carried away by water.)
Leach away: to be removed gradually by the action of a liquid.
- The nutrients leached away from the farmland over time. (They were dissolved and carried off by water.)
Leach into: to seep or percolate into a substance.
- Toxic chemicals leach into the groundwater from the old dump. (They dissolve and move into the water below.)
