Sulfur Dioxide or SO2
An air pollutant generated from the sulfur present in diesel fuel. The concentration of SO2 in the exhaust gas depends on the sulfur content of the fuel.

Sulfur Dioxide, SO2-This is a colorless gas consisting of a single sulfur atom and two oxygen atoms. Sulfur dioxide is a major primary pollutant in the atmosphere originating mostly from coal fired power plants and other fossil fuels combustion.
Sulfur Dioxide (SO2): A pungent, colorless, gas formed primarily by the combustion of fossil fuels; becomes a pollutant when present in large amounts.
Sump: A pit or tank that catches liquid runoff for drainage or disposal.
Sulfur Dioxide - A criteria air pollutant and gas produced by burning coal, most notably in power plants. Some industrial processes, such as production of paper and smelting of metals, produce sulfur dioxide.
sulfur dioxide (SO2) A pungent, colorless, gaseous pollutant formed primarily by the oxidation of sulfur, such as in anaerobic biological decomposition, and combustion of fossil fuels.
Sulfur Dioxide: A form of air pollution that is a gas. It results from the combustion of fuels that contain sulfur. SO2 is most prevalent in the combustion of coal.
SF6: Sulfur hexafluoride; a physiologically inert gas used as a tracer in building investigations.
standard sulfuric acid required to lower the pH of the water

Removal of sulfur from fossil fuels to reduce pollution.
Detection Criterion
A predetermined rule to ascertain whether a tank is leaking or not. Most volumetric tests use a threshold value as the detection criterion.
beggiatda A sulfur reducing filamentous bacteria that forms in the presence of concentrated organic matter and low dissolved oxygen.
Acid Rain Rain or any form of precipitation of dilute solutions of strong mineral acids, created by the mixing in the atmosphere of pollutants, typically sulfur dioxide and nitrogen oxides compounds, ...
Acid rain:rain that is made more acidic by sulfuric and/or nitric acid in the air, due to the burning of fossil fuels. Active volcano:a volcano that continues to erupt regularly.
0 (is acid), because of its contact with sulfur-bearing material; acid drainage is harmful because it often kills aquatic organisms.
acid rain. Precipitation which has been rendered (made) acidic by airborne pollutants.
acidic (uh-SID-ick).
'Acid rain' Rain with a very low pH (often below 4.0) resulting from emissions to the atmosphere of oxides of sulfur and nitrogen. Adaptation A confusing word used to mean quite different things.
macronutrients nutrients needed in relatively large amounts, such as phosphorus, calcium, magnesium, potassium, sulfur, nitrogen, chlorine, and sodium
macrophyte a large plant, as opposed to small and microscopic plants such as algae ...
Sulfur oxide (SOx), which causes acid rain is derived from the burning of fuel containing sulfur, mostly at power plants, and during metal smelting and other industrial processes. In the U.S., 12.46 tons of sulfur dioxide (SO2) were released in 1999.
The most important trace gases contributing to the greenhouse effect are water vapor, carbon dioxide, ozone, methane, ammonia, nitric acid, nitrous oxide, ethylene, sulfur dioxide, nitric oxide, dichlorofluoromethane or Freon 12, ...
Soil organic matter serves as the primary source of three important plant nutrients: nitrogen, phosphorus, and sulfur. Soil organic matter compounds serve as binding agents, which aggregate smaller soil particle into larger, more stable units.
Even though the problem of acid rain has been reduced, sulfur and nitrogen pollution levels must be brought down further.

Acid rain forms when certain atmospheric gases (primarily carbon dioxide, sulfur dioxide, and nitrogen oxides) come in contact with water in the atmosphere or on the ground and are chemically converted to acidic substances.
Depending on the effect sought, fireworks produce smoke and dust that contain various heavy metals, sulfur-coal compounds and other noxious chemicals.
A complex chemical and atmospheric phenomenon that occurs when emissions of sulfur and nitrogen compounds and other substances are transformed by chemical processes in the atmosphere, often far from the original sources, ...
1. A precombustion process whereby a low-sulfur coal is used in place of a higher sulfur coal in a power plant to reduce sulfur dioxide emissions. 2. Illegally using leaded gasoline in a motor vehicle designed to use only unleaded.
The core is thought to be made up of iron and nickel, as well as lighter elements such as sulfur and silicon. The core is believed to rotate at a faster rate than the rest of the planet.
Any coal tht emits less than 1.2 pounds of sulfur dioxide per milion Btu when burned. Also known as low sulfur coal.
Compliance Coating
A coating whose volatile organic compound content does not exceed that allowed by regulation.
A technology that employs a sorbent, usually lime or limestone, to remove sulfur dioxide from the gases produced by burning fossil fuels. Flue gas desulfurisation is current state-of-the art technology for major SO2 emitters, like power plants.
Precipitation containing harmful amounts of nitric and sulfuric acids formed primarily by nitrogen oxides and sulfur oxides released into the atmosphere when fossil fuels are burned.
Acidic Soil ...
For example, the equivalent weight of sulfuric acid (H2SO4 is 49 (98 divided by 2 because there are two replaceable hydrogen ions).

Strong acids, such as muriatic (or hydrochloric), sulfuric and nitric acid have many industrial uses, and can be dangerous to those not familiar to handling them. Acids are chemical "opposites" to bases, in that they can neutralize each other.
Nutrients: Elements (e.g., nitrogen and phosphorus) and trace elements (including sulfur, potassium, calcium, and magnesium) that are essential for the growth of organisms.
acid rain - the precipitation of dilute solutions of strong mineral acids, formed by the mixing in the atmosphere of various industrial pollutants -- primarily sulfur dioxide and nitrogen oxides -- with naturally occurring oxygen and water vapor.
Nutrient: element essential for plant or animal growth. Major nutrients include nitrogen, phosphorus, carbon, oxygen, sulfur, and potassium.
Strong acid An acid that, for practical purposes, ionizes completely under the conditions of interest. Common strong acids are hydrochloric, nitric, and sulfuric. See weak acid.

In environmental chemistry, an area or part of the environment in which, or a process by which, one or more pollutants is removed from the medium in which it is dispersed.
Note: For example - moist ground acts as a sink for sulfur dioxide in the air.
