a heavy, smelly gas which can be condensed into a clear liquid; used to make sulfuric acid, bleaching agents, preservatives and refrigerants; a major source of air pollution in industrial areas.

A type of refrigerant.

Sulfur dioxide is a heavy, pungent, colorless gas formed primarily by the combustion of coal, oil, and diesel fuels. Elevated levels can impair breathing, lead to other respiratory symptoms, and at very high levels aggravate heart disease. People with asthma are most at risk. Sulfur dioxide also contributes to acid rain, which can damage plants, lakes and buildings. Learn More...

A colorless gas with sharp pungent odor. Uses include beer and wine preservative, fumigation, refrigeration, and production of sulfuric acid, potassium and sodium. Hazards: Highly toxic, symptoms include irritation and burning of eyes, nose, throat.

Sulfur dioxide (chemical formula SO2 ) is an acrid-smelling gas that even at low concentrations irritates the membranes of the nose and respiratory system. It is thought to exacerbate many respiratory diseases, including asthma. Sulfur dioxide is produced whenever sulfur-containing compounds are burnt. Its commonest source in Australia is power-stations burning coal containing slight sulfur impurities.

Toxic gas composed of oxygen and sulfur.

A colorless, irritating gas formed by the burning of sulfur-containing material. Sulfur dioxide can react with other atmospheric chemicals to form sulfuric acid.

Pollutant, colorless gas with a choking odor produced by burning fossil fuels.

A colorless gas having a sharp, pungent odor. Chemically identified as SO2, sulfur dioxide is formed by burning fossil fuels that include sulfur compounds in their makeup. Sulfur dioxide is an air pollutant and an acid rain precursor. Act 141, Section 10r(3), requires all Michigan electric suppliers, beginning January 1, 2002, to disclose to customers the environmental characteristics of the average fuel mix used to produce the electricity products purchased by the customers. This disclosure will include the average air emissions, in pounds per megawatt-hour, of sulfur dioxide, carbon dioxide, and oxides of nitrogen.

A heavy toxic gas that is easily condensed to a colorless liquid and is a major air pollutant. Certain large volcanic eruptions are thought to release enough aerosols in the form of sulfur dioxide to cool the climate.

a colorless toxic gas (SO2) that occurs in the gases from volcanoes; used in many manufacturing processes and present in industrial emissions; causes acid rain

a gas, released mainly from power plants that burn coal and oil to make electricity.

A gas that causes acid rain. Burning fossil fuels, such as coal, releases SO2 into the atmosphere. Various EPA programs are reducing SO2 emissions, including the Acid Rain Program.

A strong smelling, colorless gas that is formed by the burning of fossil fuels. Power plants, which may use coal or oil high in sulfur content, can be major sources of SO2. SO2 and other sulfur oxides contribute to the problem of acid deposition. SO2 is a criteria air pollutant.

Sulfur dioxide is a product of fossil fuel combustion, such as the burning of oil or coal. Small amounts of sulfur contained in the fuel is converted into sulfur dioxide in the combustion process. Emissions of sulfur dioxide are strictly regulated, monitored and enforced by local, state and federal environmental agencies to protect people, animals and vegetation.

A major air pollutant originating mostly from the burning of fuels. Introduction Task Process Information resources Guidance Dr. Bravo Ms. Alarcón Dr. Sosa Dr. Soto Mr. Sanchez

A colorless, corrosive gas directly damaging to both plants and animals.

A colorless, poisonous gas. Affects breathing, damages plants and contributes significantly to terrestrial and aquatic acidification. Large amounts are produced as an unwanted byproduct from the combustion of sulfurous fossil fuels. Sulfur dioxide can also be oxidized to sulfur trioxide, which forms sulfuric acid when exposed to air (humidity), contributing to acidification of land and water.

Sulfur dioxide is a criteria pollutant that contributes to respiratory problems and the creation of acid rain. Sulfur dioxide is created by burning fossil fuels with trace amounts of sulfur, like coal and oil. Smaller amounts can be created during industrial metal processing. The major source of sulfur dioxide is the use of fossil fuels in electricity production. Lesser sources include other energy production and transportation.

A colorless gas that can that can bother the lungs. It is formed when fossil fuels that contain sulfur are burned. It is also given off when volcanoes erupt.

one of the six criteria pollutants, formed from burning sulfur-containing compounds, such as coal and metal refining.

SO2, the decomposition of sulfur, corrosive.

A chemical compound that when emitted to the atmosphere is considered to be a major component of acid rain. One of the criteria pollutants regulated by the 1990 Clean Air Act Amendments, SO2 is emitted mainly by anthropogenic sources. Sources include industrial point sources, such as coal fired electric utilities.

A colourless and corrosive gas that originates largely from combustion of sulfur containing fuels like coal and oil.

A colorless gas consisting of sulfur and oxygen, produced primarily by the combustion of fossil fuel.

A colorless gas released as a by-product of combusted fossil fuels containing sulfur. The two primary sources of acid rain are sulfur dioxide and nitrogen oxides.

An EPA criteria pollutant.

Gas consisting of one sulfur atom and two oxygen atoms. Sulfur dioxide is important because it converts to an aerosol that is particularly efficient at scattering light.

a colorless, very irritating gas or liquid

This is an oxide or sulfur which is emitted during the combustion of fossil fuels.

Colorless gas, odorless at low concentrations but pungent at very high concentrations. One of the major pollutants that cause acid rain. Harmful to humans and vegetation when concentrations are sufficiently high. Major sources of this pollutant are petroleum refineries, coal or oil burning power plants and diesel engines.

A toxic, irritating, colorless gas soluble in water, alcohol, and ether. Used as a chemical intermediate, in paper pulping and ore refining, and as a solvent.

A gas formed when sulfur burns in the presence of oxygen, as for example in the burning of gasoline or diesel fuel in a vehicle engine. It is a major air pollutant that is corrosive and harmful to plants and animals, especially trees.

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 is closely related to sulfuric acid, a strong acid. Sulfur dioxide plays an important role in the production of acid rain.

A strong smelling, colorless gas that is formed by the combustion of fossil fuels. Sour gas processing plants, oil sands processing plants and coal-fired power generating plants are major sources of SO2. SO2 and other sulfur oxides contribute to the problem of acid deposition.

is a gas created when coal is burned to generate electricity. Emission control equipment removes as much 85% of the sulfur dioxide from the air that is returned to the atmosphere.

A gas released by Campden tablets and other metabisulfites that sterilizes and prevents oxidation in must and mead. Harmless in recommended quantities, but may cause an allergic reaction in some people.

Acidic gas, formula SO2, formed in the combustion of many fuels and in the oxidation of naturally occurring sulfur gases. It is the primary sulfur gas emitted from combustion sources and is a precursor to sulfuric acid, which is a major constituent of acid rain.

(formula: SO2) A colorless gas with an odor like a struck match produced by burning fossil fuels that contain a percentage of sulfur such as coal, oil, and natural gas. Atmospheric emissions of sulfur dioxide combine with water vapor and oxygen to form sulfuric acid, a component of acid deposition. Sulfur dioxide is listed as a criteria pollutant.

Sulfur dioxide (also sulphur dioxide) is the chemical compound with the formula SO2. This important gas is the main product from the combustion of sulfur compounds and is of significant environmental concern. SO2 is often described as the "smell of burning sulfur."
