Where do most sulfur dioxide emissions come from?
The largest sources of SO2 emissions are from fossil fuel combustion at power plants andother industrial facilities.
How can Sulphur dioxide emissions be reduced?
Reducing Pollution One option is to use coal that contains less sulfur. Another option is to “wash” the coal to remove some of the sulfur. The power plant can also install equipment called scrubbers, which remove the sulfur dioxide from gases leaving the smokestack.
How does Sulphur dioxide cause global warming?
Sulfur dioxide (SO2) is the most voluminous chemically active gas emitted by volcanoes and is readily oxidized to sulfuric acid normally within weeks. Large volumes of SO2 erupted frequently appear to overdrive the oxidizing capacity of the atmosphere resulting in very rapid Warming.
Is Sulphur dioxide a greenhouse gas?
While sulfur dioxide isn’t a direct greenhouse gas like carbon dioxide or methane, it is considered an indirect greenhouse gas. Sulfur dioxide is regarded as an indirect greenhouse gas because, when coupled with elemental carbon, it forms aerosols.
Why Sulphur dioxide is a pollutant?
Sulphur dioxide (SO2 expressed as SOx) has long been recognized as a pollutant because of its role, along with particulate matter, in forming winter-time smog. Studies indicate that SO2 causes nerve stimulation in the lining of the nose and throat.
How is Sulphur dioxide removed from waste gases?
Sulfur dioxide may be removed from the waste gases by a process called gas scrubbing.
What are the primary sources of sulfur dioxide emissions?
Human Sources. Burning of fossil fuels such as coal,oil and natural gas are the main source of sulfur dioxide emissions.
How does sulfur dioxide affect the atmosphere?
Sulfur dioxide is a pungent, toxic gas found in Earth’s atmosphere. In addition to harming human health, the gas affects the environment by reacting with water vapor to produce acid rain. Sulfur dioxide also can react in the atmosphere to form aerosol particles, which can cause outbreaks of haze and other climate problems.
How does sulfur dioxide cause harm?
Sulfur dioxide affects the respiratory system, particularly lung function, and can irritate the eyes . Sulfur dioxide irritates the respiratory tract and increases the risk of tract infections. It causes coughing, mucus secretion and aggravates conditions such as asthma and chronic bronchitis.
How is sulfur dioxide produced from burning fossil fuels?
Many fossil fuels contain sulfur impurities. When these fuels are burned, the sulfur is oxidised to form sulfur dioxide. S (s) + O2(g) → SO2(g) This sulfur dioxide then dissolves in droplets of rainwater to form sulfurous acid.
