So2 pollution

What are the health effects of SOexposure? How is SOan air pollutant? How does sulfur dioxide affect humans? Sulfur Dioxide ( SO) Pollution.

SO from the burning of either sulfur or materials containing sulfur. The other gases in the group are much less common in the atmosphere. Along with developing the SOstandards themselves (part of the National Ambient Air Quality Standards, or NAAQS), EPA also develops requirements for how to apply or implement them, and work toward about attaining and maintaining those standards. All standards and control measures for SOinclude all sulfur oxides, as sulfur dioxide is used as the indicator due to it has a major presence in the air. Its chemical formula is SO,.

SOemissions also contribute to the secondary formation of the dangerous pollutant called fine particulate matter (PM ),. It reacts easily with other substances to form harmful compounds, such as sulfuric aci sulfurous acid and sulfate particles. About of the sulfur dioxide in air comes from human sources.

The main source of sulfur dioxide in the air is industrial activity that processes materials that contain sulfur,. Air pollution in the form of sulfur dioxide can have detrimental effects on human health. Such effects include breathing problems, particularly in asthmatics, whereas short-term exposure can lead to chest tightness and coughing and wheezing.

Using a nationwide network of monitoring sites, EPA has developed ambient air quality trends for sulfur dioxide ( SO). Under the Clean Air Act, EPA sets and reviews national air quality standards for SO2. Upon being mixed with shale or marl, and roaste the sulfate liberated sulfur dioxide gas, used in sulfuric acid production, the reaction also produced calcium silicate, a precursor in cement production.

On a laboratory scale, the action of hot concentrated sulfuric acid on copper turnings produces sulfur dioxide. It is a toxic gas responsible for the smell of burnt matches. It is released naturally by volcanic activity and is produced as a by-product of copper extraction and the burning of fossil fuels contaminated with sulfur compounds. Revised on: September 12:01pm. Chemically, it is a compound made up of one sulfur atom and two oxygen atoms.

SOforms when sulfur-containing fuel such as coal, oil, or diesel is burned. This website uses cookies. It causes coughing, mucus secretion and aggravates conditions such as asthma and chronic bronchitis. Air quality monitors measure concentrations of SOthroughout the country.

EPA, state, tribal and local agencies use that data to ensure that SOin the air is at levels that protect public health and the environment. Environmental effects. When sulfur dioxide combines with water and air, it forms sulfuric aci which is the main component of acid rain. Acid rain can: cause deforestation.

It is also emitted by trains, large ships, and some diesel equipment that burns high sulfur fuel, and by volcanic eruptions. It becomes a liquid under pressure. The subsequent impacts of acid deposition can be significant, including adverse effects on aquatic ecosystems in rivers and lakes and damage to forests, crops and other vegetation. The SOemissions are controlled using a spray dryer absorber (SDA) flue gas desulfurization system. It reacts on the surface of a variety of airborne solid particles, it is soluble in water and can be oxidised within airborne water droplets to form sulphuric acid (H SO 4), which falls as acid precipitation or acid rain.

Sulphur dioxide (SO 2) is a colourless gas. SO), which is a colourless gas with a burnt match type smell. They are formed during the burning of fuels containing sulphur, such as coal and oil, and metal-containing ores (including aluminium, copper, zinc, lead and iron).

The primary causes are deforestation and the burning of fossil fuels such as coal. As carbon dioxide levels have risen, so have its effects on air pollution. Carbon dioxide accounts for less than percent of the atmospheric gases.

However, a delicate balance exists between carbon dioxide and other gases. It does, however, have a long and evolving history with interesting transitions in line with economic, technological and political change.
