Sulfur dioxide causes acid rain. Which is the main source of so2
Answers
Sulfur dioxide (SO2) is a gas primarily emitted from fossil fuel combustion at power plants and other industrial facilities, as well as fuel combustion in mobile sources such as locomotives, ships, and other equipment. Over 100,000 tons of SO2 were emitted in 2009 in Minnesota. Current scientific evidence links SO2 exposure with adverse impacts on the respiratory system. In recent reviews of the standard, EPA has determined that even short term exposure to high levels of SO2 can have a detrimental effect on breathing function, particular for those that suffer from asthma. SO2 also reacts with other chemicals in the air to form tiny sulfate particles, contributing to levels of PM 2.5.
SO2 also reacts with other chemicals in the air to form acids, which fall to the earth as acid rain. Acid rain damages forests and crops, changes the makeup of soil, and makes lakes and streams acidic and unsuitable for fish.
