In the NASA study, lead author Dr. Bill Wolverton and his team “explored how plants and their associated microorganisms could reduce indoor air pollutants in controlled environments,” notes ...
Phytoremediation technologies use living plants to clean up soil, air and water contaminated with hazardous contaminants. [1] It is defined as "the use of green plants and the associated microorganisms, along with proper soil amendments and agronomic techniques to either contain, remove or render toxic environmental contaminants harmless". [2]
The Regional Greenhouse Gas Initiative (RGGI, pronounced "Reggie") is the first mandatory market-based program to reduce greenhouse gas emissions by the United States.RGGI is a cooperative effort among the states of Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Rhode Island, Vermont, and Virginia to cap and reduce carbon dioxide (CO 2) emissions ...
Since the release of the initial 1989 study, titled A study of interior landscape plants for indoor air pollution abatement: An Interim Report, [6] further research has been done including a 1993 paper [7] and 1996 book [8] by B. C. Wolverton, the primary researcher on the original NASA study, that listed additional plants and focused on the removal of specific chemicals.
Turning existing city infrastructure green by installing plants can filter out fine dust and noise, reduce urban heat island effects, and even reduce stress. All it takes is regreening 20 percent ...
Section 202(a)(1) of the Clean Air Act requires the Administrator of the EPA to establish standards "applicable to the emission of any air pollutant from…new motor vehicles or new motor vehicle engines, which in [her] judgment cause, or contribute to, air pollution which may reasonably be anticipated to endanger public health or welfare" (emphasis added). [3]
Biological control agents of plant diseases are most often referred to as antagonists. Biological control agents of weeds include seed predators, herbivores , and plant pathogens. Biological control can have side-effects on biodiversity through attacks on non-target species by any of the above mechanisms, especially when a species is introduced ...
After the original 30-megawatt system was shut down in 1972, total capacity has remained over 240 megawatts, delivered over a 30,000 sq mi (78,000 km 2) area. [4] On June 25, 2008, the Virginia Air Pollution Control Board voted to require Dominion Resources to adapt the plant to utilize natural gas. [9]
