(SO2) A chemical present in emissions from combustion of fossil fuels that enters the atmosphere and returns to earth with precipitation as acid rain.
A preservative which is added to most wines (although the French say they don't do this - very much). Smelly when too much is used.
a preservative used in red and white wines, indicated on the label as preservative 220. If too much is used it can separate in the wine, and the free sulphur can be smelt. It is similar to a burnt match.
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 colourless gas which is given off during fossil fuel combustion.
A polluting gas formed from sulphur. It is produced when fossil fuels are burnt.
A colourless gas produced by burning sulphur.
A pungent toxic gas that is a major pollutant associated with electric generation from sulfur fuels through non-renewable sources.
Gas formed by the burning of fossil fuels, including fuel oil and diesel fuel, that contain small amounts of sulphur. SO2 emissions can result in acidification of soils and lakes.
a greenhouse gas emission resulting from the combustion of fossil fuels.
a gas which is the leading cause in contributing to the formation of acid rain
A compound of sulphur and oxygen produced by burning sulphur.
Gas produced mostly from human activities (such as metal smelting, and fossil fuel combustion by factories, power plants and motor vehicles). Sulphur dioxide combines with water vapor to form sulphuric acid, a contributor to acid rain. Human exposure to sulphur dioxide emissions can also cause respiratory problems.
A colourless gas with irritating odour, formed when sulphur burns in air. Dissolves in water to give sulphurous acid.
EPA uses six "criteria pollutants" as indicators of air quality, and has established for each of them a maximum concentration above which adverse. SO2 is also a primary contributor to acid deposition, or acid rain, which causes acidification of lakes and streams and can damage trees, crops, historic buildings and statues. In addition, sulfur compounds in the air contribute to visibility impairment in large parts of the country. See Attainment
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
An industrial gas which is used mainly by the forest industry and is manufactured, for example, by burning elementary sulphur or by means of its recovery from process gases. It is also an acidification-causing emission that is produced when sulphur-containing fuels are burnt.
forms when sulphur combines with oxygen in the air; major air pollutant that forms both smog and acid rain; major source: industrial processes
A gas consisting of sulphur and oxygen formed during combustion of sulphur-containing fuels such as black liquor and oil. In contact with damp air, sulphur dioxide is converted into sulphuric acid which causes acid precipitation.
A poisonous gas formed by burning hydrogen sulphide (or other sulphur compounds).
