Because all Na + (sodium) and K + (potassium) and many Ca 2+ (calcium) and Mg 2+ (magnesium) salts of chloride, sulfide, and carbonate are readily soluble, it is this set of metal ions that contributes most to soil salinity. (britannica.com)
Carbon dioxide is a greenhouse gas that contributes to the increased greenhouse gas effect 8 . (naturvardsverket.se)

Carbon dioxide, the chief greenhouse gas, is emitted by burning forests to create animal pastures and by combustion of fossil fuels to operate farm machinery, trucks, refrigeration equipment, factory farms and slaughterhouses. (sfexaminer.com)
Animal agriculture generates carbon dioxide by burning forests to create animal pastures and by combustion of fossil fuels to confine, feed, transport, and slaughter animals. (farmusa.org)

SDE is in the final stages of building the second power plant in a series of 3 power plants that will be built on Chinese soil. (environmental-expert.com)
The U.S. Environmental Protection Agency has finalized a plan to clean up contaminated soil from residential properties at the Sherwin-Williams/Hilliards Creek Superfund site in Gibbsboro and Voorhees, N.J. The site includes a former paint manufacturing plant and the waters of Hilliards Creek, which flow into Kirkwood Lake. (environmental-expert.com)
Although a greenhouse gas and pollutant, carbon dioxide also supports plant growth. (eurekalert.org)
Plant residues contribute to the soil's carbon source. (kenyon.edu)
Soil-dwelling beneficial life forms may also play a role in reducing crop, livestock and human diseases, UNEP said today, as they attack and neutralize plant, animal and human pests and pathogens. (ens-news.com)
Rinorea absorbs up to 1,000 times as much nickel as most other plants, making it theoretically possible to plant fields of it in nickel-rich soils and then extract the metal from the harvested crop. (inhabitat.com)
Faculty, students and staff selected plant and soil types to analyze the effectiveness of existing combinations already commonly deployed on green roofs -- for example, different species of sedum and chives planted in a lightweight soil. (uvm.edu)
A separate area of the roof will remain plant and soil-less, serving as the all-important control by which to measure the other efforts. (uvm.edu)
The story of how soil can come to be polluted is explained by the history of manufactured gas plant (MGP) sites. (usf.edu)
Adequate plant cover keeps the soil temperature lower. (preservearticles.com)
At all depths up to 70 cm a higher temperature is observed in soil devoid of plant cover. (preservearticles.com)
With plant cover gone the battering action of wind and rains loosen the top soil which is thus carried along with water or air currents and deposited elsewhere. (preservearticles.com)
Measurements will include inputs such as those due to plant and mycorrhizal fungal production, and outputs including soil respiration. (trb.org)
Bamboo grows naturally without the need for agricultural tending and large diesel exhaust-spewing tractors to plant seeds and cultivate the soil. (outspokes.com)

Black carbon is the sooty part of the particulates emitted from combustion. (europa.eu)

A few centuries of fossil fuel-based civilization have brought our very survival under threat by rupturing the Earth's carbon cycle, disrupting key climate systems and self-regulatory capacity, and pushing diverse species to extinction at 1000 times the normal rate. (commondreams.org)

Primary pollutants in particular are known for their corrosive properties, which can cause damage to ecosystems as well as manmade infrastructure. (worldatlas.com)
Many of these so-called xenobiotic (from Greek xenos , "stranger," and bios , "life") chemicals have been found to be carcinogens or may accumulate in the environment with toxic effects on ecosystems (see the table of major soil pollutants). (britannica.com)
Excess deposition of air pollutants can lead to disturbances in the function and structure of ecosystems. (europa.eu)

An oversimplified perception of the soil carbon cycle has left scientists with a glaring uncertainty as to whether soil would help mitigate future carbon dioxide levels -- or make them worse, Sulman said. (eurekalert.org)

The advent of the "energy crisis" a number of years back has increased the problems associated with indoor pollutants. (umn.edu)
Bringing in outside air and exhausting indoor air (ventilation) dilutes or removes the indoor pollutants and moisture. (ndsu.edu)

Primary pollutants are produced directly from a source but secondary pollutants are produced by reactions between primary pollutants and other chemicals. (worldatlas.com)
Many experts report that secondary pollutants can cause much greater damage to the environment than primary pollutants. (worldatlas.com)
Additionally, these substances are of particular concern given their variability and propensity to form from a wide range of primary pollutants. (worldatlas.com)

She investigated a technique to improve the cleanup of contaminated soils at MGP sites. (usf.edu)
This entry addresses the cleanup of contaminated soil and water. (pollutionissues.com)

Our collaboration with American Forests provides us with a great opportunity to help the local climate by planting trees and reducing our carbon footprint. (asaecenter.org)
Organizations can make a real difference in the health of our planet by planting trees to offset the carbon footprint of their meetings and conventions," says Scott Steen FASAE, CAE, CEO and president at American Forests. (asaecenter.org)
Planting trees in carefully chosen forest restoration projects is one of the most cost effective ways to sequester carbon, plus it has all sorts of added benefits for the environment. (asaecenter.org)
However, when trees are used for building construction, furniture, etc, the carbon is not released rapidly into the environment. (environmentalchemistry.com)
Trees also filter some pollutants out of the water and soil, and they can prevent or control flooding . (thegreenspotlight.com)

Crop production problems in agriculture are encountered when excess salinity ( salt accumulation) occurs in soils in arid climates where the rate of evaporation exceeds the rate of precipitation . (britannica.com)
Two of the most common quality issues are excess humidity and pollutants. (ndsu.edu)

Understanding details about which contaminants are making their way into the soil, waterways, and air is important in order to combat any damage they may cause. (worldatlas.com)
