The effects of SO2 on people and the environment vary widely depending on (1) the amount of gas a volcano emits into the atmosphere; (2) whether the gas is injected into the troposphere or stratosphere; and (3) the regional or global wind and weather pattern that disperses the gas. Sulfur dioxide (SO2) is a colorless gas with a pungent odor that irritates skin and the tissues and mucous membranes of the eyes, nose, and throat. Sulfur dioxide chiefly affects upper respiratory tract and bronchi. The World Health Organization recommends a concentration of no greater than 0.5 ppm over 24 hours for maximum exposure. A concentration of 6-12 ppm can cause immediate irritation of the nose and throat; 20 ppm can cause eye irritation; 10,000 ppm will irritate moist skin within minutes.
Emission rates of SO2 from an active volcano range from <20 tonnes/day to >10 million tonnes/day according to the style of volcanic activity and type and volume of magma involved. For example, the large explosive eruption of Mount Pinatubo on 15 June 1991 expelled 3-5 km3 of dacite magma and injected about 20 million metric tons of SO2 into the stratosphere. The sulfur aerosols resulted in a 0.5-0.6°C cooling of the Earth's surface in the Northern Hemisphere. The sulfate aerosols also accelerated chemical reactions that, together with the increased stratospheric chlorine levels from human-made chlorofluorocarbon (CFC) pollution, destroyed ozone and led to some of the lowest ozone levels ever observed in the atmosphere.
At Kilauea Volcano, the recent effusive eruption of about 0.0005 km3/day (500,000 m3) of basalt magma releases about 2,000 tonnes of SO2 into the lower troposphere. Downwind from the vent, acid rain and air pollution is a persistent health problem when the volcano is erupting.
So the answer is yes, volcanoes do release Sulfur Dioxide.
What else can I help you with?
Is sulfur found in Hawaii?
There is some sulfur in Hawaii, as there is wherever there are volcanoes. There is an attraction called the Sulfur Banks in Hawaii Volcanoes National Park. There has recently been an air quality advisory that there is sulfur dioxide in the air. However, there is not enough sulfur to be commercially mined.
How do you separate sulphur dioxide?
Sulfur dioxide can be separated by processes such as scrubbing, which involves passing the gas through a liquid that reacts with and removes the sulfur dioxide. Another method is precipitation, where a chemical is added to cause sulfur dioxide to form a solid that can be separated from the gas.
How is sulfur dioxide form?
Sulfur dioxide (also sulphur dioxide) is the chemical compound with the formula SO2. It is produced by volcanoes and in various industrial processes. Since coal and petroleum often contain sulfur compounds, their combustion generates sulfur dioxide unless the sulfur compounds are removed before burning the fuel. Further oxidation of SO2, usually in the presence of a catalyst such as NO2, forms H2SO4, and thus acid rain.[2] Sulfur dioxide emissions are also a precursor to particulates in the atmosphere. Both of these impacts are cause for concern over the environmental impact of these fuels.
How is sulfur dioxide produced?
Sulfur dioxide is typically produced by the burning of fossil fuels containing sulfur, such as coal and oil. It can also be released during volcanic eruptions and through certain industrial processes like metal smelting and paper production.
Which elements are present in sulfur dioxide?
Sulfur and oxygen are present in sulfur dioxide.
What is the primary source of sulfur dioxide?
Volcanoes produce more sulfur dioxide than any other cause. Some sulfur dioxide is also release from the burning of sulfur-rich fossil fuels.
Is sulfur dioxide emitted from a volcano?
Volcanoes often emit a harmful gas called sulfur dioxide. Sulfur dioxide is an air pollutant. It causes acid rain.
What are the two main gases in a volcanoes emit?
Steam, Sulfur dioxide, Carbon Dioxide.
Are they any volcanoes contributing to air pollution?
Most active volcanoes release sulfur dioxide and carbon dioxide into the atmosphere, which is air pollution
What material erupted from volcanoes that is important in acid rain?
sulfur dioxide

There is some sulfur in Hawaii, as there is wherever there are volcanoes. There is an attraction called the Sulfur Banks in Hawaii Volcanoes National Park. There has recently been an air quality advisory that there is sulfur dioxide in the air. However, there is not enough sulfur to be commercially mined.
What types of gases are found in volcanoes?
Here are some: Steam, Carbon Dioxide , Sulfur Dioxide , Hydrogen Sulfide
Why does it smell around volcanoes?
Because of the large amounts of sulfur usually present where molten rock is close to the surface.
What gasses come from volcanoes?
i can only name one. One of them is sulfur dioxide. Sincerely, Dan
What acid does sulfur dioxide form?
Sulphur dioxide is an intermediate towards producing Sulphurous acid. It is a chemical compound produced by volcanoes, burning coal and petrol, such fumes passing into the air produce acid rain thus are a cause for being an environmental concern.
