Gas produced by burning sulphur-containing fuels and as a by-product in chemical pulping Reacts with oxygen and water vapour in the air to produce sulphuric and sulphurous acids, which dissolve in rain, causing acidification of soil and water
Used to kill wild yeast's, sterilize equipment and prevent oxidation A naturally occurring substance
A colourless gas, consisting of molecules of sulphur (1) and oxygen (2) atoms, which is given off during fossil fuel combustion
sulfur dioxide: 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 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 sulfurous acid and, in the presence of oxygen, sulfuric acid, and is thus responsible for acid rain
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 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
A colorless gas formed during the burning of fuels containing sulfur, such as coal Breathing SO2 may irritate the respiratory system and aggravate asthmatic symptoms
A colorless, irritating gas formed by the burning of sulfur-containing material Sulfur dioxide can react with other atmospheric chemicals to form sulfuric acid
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
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
Poisonous gas primarily produced by burning coal, most notably in power plants Also a by-product of certain industrial processes, such as the production of paper and metal smelting Involved in the formation of acid rain
A colorless, extremely irritating gas or liquid, SO, used in many industrial processes, especially the manufacture of sulfuric acid. the American spelling of sulphur dioxide. Inorganic compound, heavy, colourless, poisonous gas (SO2). It has a pungent, irritating odour (the smell of a just-struck match). It occurs in volcanic gases and dissolved in the waters of some warm springs. Huge quantities are made industrially for use as a bleach, as a reducing agent, and as sulfites, which are food preservatives. It is a precursor of the trioxide (SO3), used to make sulfuric acid. Sulfur dioxide is formed when sulfur-containing fuels are burned; in the atmosphere it can combine with water vapour to form sulfuric acid, a major component of acid rain
A compound used to inhibit the growth of undesirable microorganisms and inhibit browning It gives an unpleasant match stick odor to wine when present in noticeable quantities
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 consisting of one sulfur atom and two oxygen atoms It is produced by life, by volcanoes, and during the combustion of fuels containing sulfur In the atmosphere it is converted into sulfuric acid aerosol, which may form hazes and serve as cloud condensation nuclei
A gas produced from volcanic eruptions, ocean spray, organic decomposition and the burning of fossil fuels Sulfur dioxide is a component in the creation of acid precipitation This colorless gas has the chemical formula 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
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
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 heavy, pungent, colorless gas formed primarily by the combustion of fossil fuels This major air pollutant is unhealthy for plants, animals, and people
a gas (SO2) consisting of one sulfur and two oxygen atoms Of interest because sulfur dioxide converts to an aerosol that is a very efficient light scatterer Also, it can convert into acid droplets consisting primarily of sulfuric acid
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 in the atmosphere to sulfate aerosols These aerosols result in negative radiative forcing (i e , tending to cool the Earth's surface)
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
