How does sulfur dioxide cause air pollution?
Sulfur dioxide (SO2) results from the combustion of fuels containing sulfur or sulfurous chemicals, the combustion of H2S in flares, paper production, and the smelting of ores containing sulfides.
SO2 exhausted to the atmosphere may cause respiratory problems in sensitive individuals such as asthmatics. It can also cause damage to plants and trees, such as the reddening of pine needles. It can hasten the corrosion of iron and other metals.
If the SO2 combines with water vapour, it can cause acid precipitation which can erode metal and limestone, impact the ionic balance of clay soils, fade paints and change the pH of river and lake water to the detriment of fish and other aquatic organisms.
In all of these cased the impact of atmospheric SO2 is to combine with water in plant ot animal cells, atmospheric water, or standing water to make sulfurous acid (H2SO3). If the SO2 oxidizes in the atmosphere to sulfur trioxide (SO3) it can combine with water to form sulfuric acid (H2SO4) with stronger environmental chemical reactions.
lichens are sensitive to sulfur dioxide, they are biological indicators. The cleaner the air the more lichens will grow. Therefore if there are houses right by a road, if you look on the roof there would be less lichens as there would be more sulfur dioxide in the air because of pollution. Hope this helps By Troy Flynn
Basically, sulfur dioxide is a acidic gas. As acid reacts with alkali, carbonates and metals, all 3 are actually ideal to remove sulfur dioxide. However, in the context of removing sulfur dioxide due to air pollution, reacting sulfur dioxide with alkali and carbonate would be more appropriate. For example, removing sulfur dioxide with calcium carbonate would result in calcium sulfate, water and carbon dioxide.
this affect planets and animails by the air pollution. Coming from the air pollution is carbon dioxide with kill animals by the old oxgyen laying on there food, which then the animals eat. Plants will also die by air pollution, by atmosphere carbon dioxide which then it burns to the soil and kills the roots then leading to no more plants for the animals to eat.
Sulfur dioxide is a gas. 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. About 99% 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, eg the generation of electricity from coal, oil or gas that contains…
The main human cause of air pollution is probably the burning of fossil fuels in industry, transport and to generate electricity. This releases additional carbon dioxide which is seriously damaging our planet by causing global warming. The US EPA has classified carbon dioxide as a pollutant. As well as carbon dioxide, fossil fuel burning releases many other pollutants, such as carbon monoxide, nitrogen oxides, sulfur oxides, and hydrocarbons.
