Sulphur dioxide pollution

Why is sulfur dioxide produced when fuels are burnt? What causes sulphur dioxide? The other gases in the group are much less common in the atmosphere. Health Effects: High concentrations of sulfur dioxide (SO 2) can result in breathing problems with asthmatic children and adults who are active outdoors.

Short-term exposure has been linked to wheezing, chest tightness and shortness of breath. Other effects associated with longer-term exposure to sulfur dioxide ,. It is also produced in the burning of fossil fuels on industrial facilities, by the extraction of metal from ore or by vehicles such as cars, ships or locomotives that burn fuel. This atmospheric deposition can damage vegetation, affect soils, acidify lakes and streams, and ruin memorials, buildings, and statues at our national cultural monuments. The primary anthropogenic sources of sulfur dioxide emissions are the burning of high-sulfur coals and heating oils in power plants, followed by industrial boilers and metal smelting. It is invisible and has a nasty, sharp smell.

It reacts easily with other substances to form harmful compounds, such as sulfuric acid , sulfurous acid and sulfate particles. Using a nationwide network of monitoring sites, EPA has developed ambient air quality trends for sulfur dioxide (SO2). Sulfur dioxide is a gas. Under the Clean Air Act, EPA sets and reviews national air quality standards for SO2.

In addition, the concentration of sulfur dioxide in the atmosphere can influence the habitat suitability for plant communities, as well as animal life. Chemically, it is a compound made up of one sulfur atom and two oxygen atoms. SOis also part of a larger group of compounds found in the atmosphere called “ sulfur oxides” (SOx). This site provides information about sulfur dioxide and its effects.

It is produced by burning fossil fuels and by the smelting of mineral ores that contain sulfur. Erupting volcanoes can be a significant natural source of sulfur dioxide emissions. Such effects include breathing problems, particularly in asthmatics, whereas short-term exposure can lead to chest tightness and coughing and wheezing.

Sulphur dioxide (SO 2) is a colourless, nonflammable gas with a penetrating odour that irritates the eyes and air passages. It reacts on the surface of a variety of airborne solid particles, is soluble in water and can be oxidised within airborne water droplets. Exposure is primarily seen in the occupational setting. Solutions adapted to each situation.

SO emissions are proportional to feed sulphur content. Count on our experts to help you. National Ambient Air Quality Standards (NAAQS) for SO specify maximum amounts of sulfur dioxide to be present in outdoor air. See primary NAAQS for SO for an in-depth explanation of the current SO primary (health-based) standards, including Federal Register citations and fact sheets. Btu, with lower emissions produced by either lower sulfur content or higher Btu content.

As an incentive for reducing emissions, for each ton of sulfur dioxide reduced below the applicable emissions limit,. Revised on: September 12:01pm. Emission Sources and Trends. Current methods to lessen sulfur release such as coal washing, switching to low sulfur fuels, or fluidized bed combustion is not being employed at the level it needs to be for significant change. Ideally, if an industrial source of sulfuric pollution could utilize multiple methods of controlling emissions,.

Crude oil contains sulphur which, following combustion in the engine, ends up in ship emissions. Sulphur oxides (SO x) are known to be harmful to human health, causing respiratory symptoms and lung disease. In the atmosphere, SO x can lead to acid rain, which can harm crops, forests and aquatic species,.
