What are the 3 sources of sulfur dioxide emissions?
Most of the sulfur dioxide released into the environment comes from electric utilities, especially those that burn coal. Some other sources of sulfur dioxide include petroleum refineries, cement manufacturing, paper pulp manufacturing, and metal smelting and processing facilities.
What produces sulfur dioxide emission?
Sulfur dioxide (SO2) is a colourless gas with a sharp, irritating odour. 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.
What is the largest source of sulfur dioxide emissions?
fossil fuel combustion
The largest sources of SO2 emissions are from fossil fuel combustion at power plants andother industrial facilities.
What is the main source for sulfur oxides?
Volcanoes are a natural source of sulfur oxides in the atmosphere, but 99% of the sulfur dioxide in the atmosphere comes from human activity, such as burning coal, oil, and gas to make electricity and heat. When coal and oil burn, the sulfur in them combines with oxygen in the air to make sulfur oxides.
Which of the following is the source of SO2 pollution?
These gases, especially SO2, are emitted by the burning of fossil fuels — coal, oil, and diesel — or other materials that contain sulfur. Sources include power plants, metals processing and smelting facilities, and vehicles.
What is the major source of Sulphur dioxide Mcq?
Which is the major source for sulphur dioxide? Explanation: Though emission of sulphur dioxide is peak during volcanic eruptions, its major source is during combustion of crude oil and coal for heat and power generation.
Which of the following are natural contributors to Sulphur dioxide in the atmosphere?
Explanation: Though primary natural contributor to sulphur dioxide is volcanic eruptions, even sea sprays and decaying vegetation release sulphur dioxide to the atmosphere.
Which is the major source of air pollutants sulphur dioxide?
Coal burning releases the largest amount of sulphur dioxide air pollution.
What is a natural source of sulfur dioxide in the atmosphere?
Natural sources (volcanoes, fires, phytoplankton) produce sulfur dioxide, but burning sulfur-rich fossil fuels—primarily coal, oil, and petroleum—is the main source of the gas. Smelter ovens, which are used to concentrate metals found in ore, also produce it.
Why is Sulphur dioxide considered an air pollutant?
Correct option D It is a strong oxidant and oxidizes other components of atmosphere Explanation:Sulphur dioxide SO2 is considered as air pollutant because it readily undergoes oxidation in the atmosphere to form Sulphur trioxide SO3.
Is sulfur dioxide primary or secondary pollutant?
Examples of primary pollutants include sulfur dioxide (SO2), carbon monoxide (CO), nitrogen oxides (NOX), and particulate matter (PM). Examples of secondary pollutants include photochemical oxidants (ozone, nitrogen dioxide, sulfur trioxide) and secondary particulate matter.
What is the main source of sulphur dioxide in South Africa?
coal-fired power stations
The most important sources for SO2 emissions are coal-fired power stations, smelter sites, oil and gas industry installations, and volcanoes.
