Exposure to sulfur dioxide emissions by coal power plants (coal PM 2.5) in the US was associated with 2.1 times greater mortality risk than exposure to PM 2.5 from all sources. [53] Meanwhile, the Southern Hemisphere had much lower concentrations due to being much less densely populated, with an estimated 90% of the human population in the north.
Sulfur dioxide emissions increased on March 12, 2008, when a new vent opened. The increased vog level has caused evacuations and damaged crops. In the summer of 2008 and in 2012, the County of Hawaiʻi received a disaster designation due to the agricultural damage.
Acid rain can have harmful effects on plants, aquatic animals, and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids. Acid rain has been shown to have adverse impacts on forests, freshwaters, soils, microbes, insects and aquatic life ...
The group warned that illegal fireworks that contain lead can cause long-term damage, although inhaling gases like carbon dioxide, carbon monoxide, and sulfur dioxide can make it hard to breathe.
After 1 tonne of crop residue is burnt in a field there is a release of 1,400 kg of carbon dioxide (CO 2), 58 kg of Carbon Monoxide (CO), 11 kg of particulate matter, 4.9 kg of nitrogen oxides (NO x), [37] and 1.2 kg of sulfur dioxide (SO 2). [36]
Title IV of the Clean Air Act Amendments of 1990 established the allowance market system known today as the Acid Rain Program. Initially targeting only sulfur dioxide, Title IV set a decreasing cap on total SO 2 emissions for each of the following several years, aiming to reduce overall emissions to 50% of 1980 levels.
The United States has a "cap-and-trade" program for two of the major pollutants, sulfur dioxide and nitrogen oxides. [15] The Acid Rain Program, as it is known, applies to power plants that use fossil fuels, and was required by the Clean Air Act of 1990.
Illustration of air pollutants generated by U.S. power plants (includes both coal-fired and oil-fired plants) During combustion, the reaction between coal and the air produces oxides of carbon, including carbon dioxide (CO 2, an important greenhouse gas), oxides of sulfur (mainly sulfur dioxide, SO 2), and various oxides of nitrogen (NO x).
