Radionuclides are radioactive elements that are naturally present in rocks and soil but they also may be man-made.
On the technological front, engineers are hard at work developing man-made ways to capture the carbon spewing from coal-fired power plants and industrial smokestacks and sequester it by burying it deep within the Earth or the oceans.
In this series of experiments, the students will study whether familiar materials, both natural and man-made can be utilized as carbon sources by consortia of microorganisms obtained from soil samples.
Climate change refers to the buildup of man-made gases in the atmosphere that trap the suns heat, causing changes in weather patterns on a global scale.
There are many types of pollutants, both human-made and natural, that wash into our lakes, rivers, streams, wetlands, and coastal waters and percolated into our groundwater every year.
The major source of man-made CO2 emissions is from the combustion of fossil fuels. Carbon dioxide is the primary greenhouse gas and is known to contribute to global warming and climate change.
Natural products do not contain any man-made (synthetic) ingredients. On food, "Natural" or "All Natural" labels are not meaningful because the federal standard is weak.
These models do not unambiguously attribute the warming that occurred from approximately 1910 to 1945 to either natural variation or human effects; however, they suggest that the warming since 1975 is dominated by man-made greenhouse gas emissions.
Oxidation Pond: A man-made (anthropogenic) body of water in which waste is consumed by bacteria, used most frequently with other waste-treatment processes; a sewage lagoon.
Note: The contamination of the natural environment by some man-made compounds may be so widespread that it is practically impossible to get access to biota with a truly natural level; only ‘normal’ levels can be measured, ...
Air Pollution - How the air we breathe is contaminated by man-made or natural particles, liquids or gases. This could include everything from factory exhaust to emissions from our cars.
irrigation: Irrigation is when man-made water channels are used to bring in water to grow crops.
Volatile Organic Compounds (VOCs): compounds that vaporize easily and have low water solubility that are often human-made chemicals used and produced in the manufacture of paints, pharmaceuticals, ...
3. Areas where the climate or man-made changes have occurred more quickly than local species could adapt.
The process is characterized by development of an environment rich in nutrients and consequent proliferous plant production. Man-made eutrophication of inland water courses and shallow coastal waters is caused by excessive discharge of nutrients, ...
Irrigation: The controlled application of water for agricultural purposes through human-made systems to supply water requirements for crops not satisfied by rainfall.
Natural flows. Flows, typically in the Santa Ana River, that are not placed into the system by man-made activities.
Non-interruptible. Water from MWD that is not subject to any interruption.
A waterway constructed or altered primarily to carry water from man-made structures such as terraces, subsurface drains, diversions and impoundments.
OVERFLOW CHAMBER ...
The level of use, at a given level of management, at which a natural or man-made resource can sustain itself over a long period of time.
Topography. The configuration of a surface including its relief and the position of its natural and man-made features. The shape of a surface.
The water is cleaned as it slowly travels downward and eventually reaches an underground aquifer. The purpose of man-made percolation ponds is both to clean the water and to keep the ground from sinking.
The Convention's primary objective is the "stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic (man-made) interference with the climate system.
Part of project management concerned with identifying through a formal written technical evaluation likely impact (positive and negative) of a proposed development or activity on natural and man-made environment.
Haze (Hazy): A phenomenon that results in reduced visibility due to the scattering of light caused by aerosols. Haze is caused in large part by man-made air pollutants.
