Biodegradation
The natural process involved in recycling waste or breaking down organic matter into nutrients that can be used by other living organisms.
degradation
The changing of a soil to a more highly leached and weathered state, usually accompanied by morphological changes such as the development of an eluviated, light-colored A (Ae) horizon.
dehydrogenase ...
degradation The transformation over time of a compound into one or more similar chemicals through either a chemical or biological breakdown.
degradation : Chemical or biological breakdown of a complex compound into simpler compounds.
denitrification : Bacterial reduction of nitrite to gaseous nitrogen under anaerobic conditions.
Degradation
1) The process by which a chemical is reduced to a less complex form. 2) The physical destruction or decomposition of a clothing material due to exposure to chemicals, use, or ambient conditions (i.e., storage in sunlight).
Biodegradation
Decomposition or breakdown of a substance through the action of microorganisms (such as bacteria or fungi) or other natural physical processes (such as sunlight).
biodegradation
Breakdown of a substance catalysed by enzymes in vitro or in vivo. This may be characterized for purposes of hazard assessment as: ...
Non-degradation
An environmental policy that disallows any lowering of naturally occurring quality regardless of pre-established health standards.
Non-Ferrous Metals ...
Biodegradation
Transformation of a substance into new compounds through biochemical reactions or the actions of microorganisms such as bacteria.
Biogas ...
Land degradation: The reduction or loss of the biological or economic productivity from rainfed cropland, irrigated cropland, or range, pasture, forest and woodlands. Land degradation usually results from unsustainable land use.
Anti-Degradation Clause
Part of federal air quality and water quality requirements prohibiting deterioration where pollution levels are above the legal limit.
Anthropogenic ...
Limited Degradation
An environmental policy permitting some degradation of natural systems but terminating at a level well beneath an established health standard.
Limiting Factor ...
Degradation: The process by which a chemical is reduced to a less complex form.
Degradation Potential: The degree to which a substance is likely to be reduced to a simpler form by bacterial activity.
Degradation of the Web of Life - In some ways, the connections between the different forms of life on earth are robust. Most organisms have a variety of food sources and can withstand some amount of habitat change.
Land degradation in arid, semi-arid and dry sub-humid areas resulting from various factors, including climatic variations and human activities.
degradation Chemical or biological breakdown of a complex compound into simpler compounds. degrees of calcium carbonate concentrationCalcium carbonate concentration is commonly expressed as degrees.
Air Pollution: Degradation of air quality resulting from unwanted chemicals or other materials occurring in the air. (See also air pollutants.) ...
Eutrophication: degradation of water quality due enrichment by nutrients, primarily nitrogen (N) and phosphorus (P), which results in excessive plant (principally algae) growth and decay.
Desertification:the process by which semiarid lands turn to desert (also called land degradation). It is caused by prolonged drought, during which time the top layers of soil dry out and blow away.
degradation erosion of a stream's channel; the inverse of aggradation
delta a deposit of sand, silt, and clay where swift waters enter a slower body of water and drop their sediment load.
Landfill Design and Technology May Enhance Biodegradation
Some landfills are now being designed to promote biodegradation through the injection of water, oxygen, and even microbes.
It also describes the degradation of dry but productive land to the point where the land can no longer produce food or sustain life.
Atmospheric data have recently shown that the systematic banning of anthropogenic chlorine-containing compounds, CFCs such as Freon-11 and Freon-12, beginning with the Montreal Protocol in 1986, have stopped the degradation of stratospheric ozone, ...
The grade measures the amount of wear, natural mishaps and other surface degradation a coin has received after leaving the coining press.
desertification The progressive destruction or degradation of vegetative cover especially in arid or semiarid regions bordering existing deserts.
Composting The controlled aerobic degradation of organic wastes into a material which can be used for landscaping, landfill cover, or soil conditioning.
Compound A substance composed of two or more elements.
This includes Absorption (from the moment of entry at ingestion or initial exposure), Distribution (and transport throughout the body), Metabolism (biochemical modification or degradation, usually through specialized enzymatic systems) and Excretion ...
The process by which a compound is reduced in concentration over time, through absorption, adsorption, degradation, dilution, and/or transformation.
In view of the different contributions to global degradation States have common but differentiated responsibilities.
Diamonds produced without the involvement of violence, human rights violations or environmental degradation. The Conflict-Free Diamond Council examines the entire supply chain-from mine to consumer-before certifying that a diamond is conflict-free.
Activated carbon that supports active microbial growth, in order to aid in the degradation of organics that have been absorbed on its surface and in its pores.
Biological oxidation ...
Externalities: The inadvertent impact of one person's activity on the well-being of another person. Many aspects of environmental degradation, such as air pollution, global warming, loss of wilderness, and contamination of water bodies, ...
Data that characterize a pesticide's fate in the ecosystem, considering factors that foster its degradation (light, water, microbes), pathways and resultant products.
Environmental Impact Statement ...
REDD = reductions in deforestation and degradation (in developing countries), (global scheme promoting projects for first world countries to finance) ...
Dioxins
a group of toxic organic substances, containing carbon, hydrogen, oxygen and chlorine, resistant to biodegradation, produced when organic material is incinerated at low temperatures.
Biologically activated carbon: Activated carbon that supports active microbial growth, in order to aid in the degradation of organics that have been absorbed on its surface and in its pores.
Environmental Fate Data: Data that characterize a pesticide's fate in the ecosystem, considering factors that foster its degradation (light, water, microbes), pathways and resultant products.
Attenuation: The process of reduction of a compound's concentration over time. This can be through absorption, adsorption, degradation, dilution or transformation.
a term used to 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, ...
Subsets of essential fish habitat that serve an important ecological function, are particularly sensitive to human-induced environmental degradation, are particularly stressed by human development activities, or comprise a rare habitat type.
Past high grading may leave hardwood stand composition and quality in bad shape. High grading is an abusive practice where the stand is entered and only the best trees are removed resulting in an overall degradation of stand quality.
Once you have moved into your building, be sure and keep track of the VOC content of your cleaning materials too, they can also contribute to indoor air quality problems and environmental degradation.
