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.

is a strong smelling, colorless gas that is formed by the combustion 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 [..]

(American spelling,inorganic compound) A toxic gas, of molecular formula SO₂ that is found in the emissions of volcanos and those of burning coal or petroleum; dissolves in water to form [..]

An atmospheric pollutant formed by the oxidation of sulfur; it contributes to acid rain.

A poisonous gas created during the combustion of fossil fuels when sulfates combine with oxygen.

A gaseous chemical compound. It is produced by volcanoes and in various industrial processes. Since coal and petroleum often contain sulfur compounds, their combustion generates sulfur dioxide. A redu [..]

A heavy, smelly gas that 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 pungent, colorless, gasformed primarily by the combustion of fossil fuels; becomes a pollutant when present in large amounts.

A pungent, colorless, gasformed primarily by the combustion of fossil fuels; becomes a pollutant when present in large amounts.

A colorless, reactive gas produced during the burning of sulfur-containing fuels such as coal and oil, during metal smelting, and during other industrial processes. Generally, the highest concentratio [..]

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.

A highly toxic, colorless, nonflammable gas. It is used as a pharmaceutical aid and antioxidant. It is also an environmental air pollutant.

A highly toxic, colorless, nonflammable gas. It is used as a pharmaceutical aid and antioxidant. It is also an environmental air pollutant.

A compound composed of one sulfur and two oxygen molecules. Sulfur dioxide emitted into the atmosphere through natural and anthropogenic processes is changed in a complex series of chemical reactions [..]

SO2

A criteria air pollutant. Sulfur dioxide is a 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.

, 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 [..]

A gas formed when fuel containing sulfur, such as coal or oil, is burned. S02 dissolves in water vapour to form acid, and interacts with other gases and particles in the air to form sulfates and other [..]

A strong smelling, colorless gas that is formed by the combustion 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 pollutant.

An old refrigerant.

greenhouse gas that can cause acid rain.

Chemical compound produced when boilers burn fuel that contains sulfur. Of the fuels used in the paper industry, oil and coal generally contain the highest quantities of sulfur.

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 heavy, pungent, colorless air pollutant formed primarily by the combustion of fossil fuels. It is a respiratory irritant, especially for asthmatics.

One compound of the family of sulfur oxide gases (SOx). These gases are formed when fuel containing sulfur – such as coal and oil – is burned, when gasoline is extracted from oil, and/or when metals a [..]

One of several forms of sulfur in the air, sulfur dioxide is an air pollutant generated principally from combustion of fuels that contain sulfur (i.e. coal and other fossil fuels).

A pungent, colorless, gaseous pollutant formed primarily by the combustion of fossil fuels.
