Carbon monoxide, sulfur dioxide and nitrogen oxides produced by industry and motor vehicles are common air pollutants.

Such technology could cut acid rain — causing sulfur dioxide emissions by more than 90 percent, smog - forming nitrogen oxides by 75 percent, and — ultimately — capture more than 80 percent of the CO2 normally produced by combustion, storing it in nearby depleted oil fields by 2015.

If engineers were to spray about 10 million metric tons of sulfur dioxide droplets into the stratosphere each year between 2020 and 2070, the number of storm surge inundations produced by large hurricanes each year after 2070 drops by about half, the researchers report online today in the Proceedings of the National Academy of Sciences.

Interestingly, he consulted the literature in a rather unexpected subject while conducting these calculations: winemaking — a science that involves, in part, dissolving sulfur dioxide in water to produce sulfites and bisulfites under oxygenless conditions similar to those on early Earth.

Ultimately, he found that, while volcanic eruptions would have spewed huge quantities of both sulfur dioxide and hydrogen sulfide into the atmosphere, it was the former that dissolved more easily in shallow waters, producing large concentrations of sulfidic anions, in the form of sulfites and bisulfites.

The sulfur could produce torrents of acid rain, the carbon dioxide and methane could lead to rapid greenhouse warming, and life on Earth just might not have been worth living for a while.

The reaction thought to occur before 2.4 billion years ago is that sulfur dioxide produced by volcanos is separated into native sulfur and sulfuric acids by ultra violet light.

In particular, aircraft jet engines produce carbon dioxide (CO2), water vapor (H2O), nitrogen oxides (NOx), carbon monoxide (CO), oxides of sulfur (SOx), unburned or partially combusted hydrocarbons (also known as volatile organic compounds, or VOCs), particulates, and other trace compounds.

Natural gas is much more environmentally friendly than coal, which continues to be the mainstay of electricity production around the world and in the U.K. Gas emits less than half the CO2 per kilowatt hour produced, and it emits much lower amounts of other pollutants like nitrous oxide, sulfur dioxide, black carbon, carbon monoxide, mercury, and particulates.

Compared to petroleum diesel fuel, which is refined from crude oil, biodiesel combustion produces fewer air pollutants such as particulates, carbon monoxide, sulfur dioxide, hydrocarbons, and air toxics.

The protocol embraces six greenhouse gases, carbon dioxide, methane, nitrous oxide and industrial gases HFCs, PFCs and sulfur hexafluoride (SF6), that are combined in a «basket», so that individual gases are translated into CO2 equivalents, which are then added up to produce a single figure.

Each day almost 50,000 tons of unpleasant, and sometimes poisonous, sulfur dioxide are added to the atmosphere, and our automobiles produce almost 300,000 tons of other pollutants.

In response, the IPCC added a cooling factor to its models of the atmosphere, consisting of tiny aerosol particles produced by the emission of sulfur dioxide from electric power plants.

Cap and trade was first used to remove lead from gasoline and then worked into amendments to the Clean Air Act in 1990 to force power plants to cut back on sulfur dioxide, one of the chemicals that produce acid rain.

Sulfur dioxide (SO2): Produced when the sulfur in coal reacts with oxygen, SO2 combines with other molecules in the atmosphere to form small, acidic particulates that can penetrate human Sulfur dioxide (SO2): Produced when the sulfur in coal reacts with oxygen, SO2 combines with other molecules in the atmosphere to form small, acidic particulates that can penetrate human sulfur in coal reacts with oxygen, SO2 combines with other molecules in the atmosphere to form small, acidic particulates that can penetrate human lungs.

Another method - wet milling - produces an odor because it requires the input of sulfur dioxide.

When fossil fuels are burned they produce gasses (most significantly carbon dioxide, but others as well, including sulfur dioxide) which are released into, and pollute, the atmosphere.

The Tennessee Valley Authority's Gallatin Fossil Plant, near Nashville, is set for a $ 1.1 billion environmental upgrade, a suite of sulfur dioxide scrubbing and ozone - busting equipment that operators hope will enable it to produce power through the next century.

One type of sulfur oxide, sulfur dioxide, is produced by burning fuel that contains high levels of sulfur.

Better air quality: If the same amount of electricity as that generated by America's 10,000 - MW wind turbine fleet were instead produced using the average utility fuel mix, it would emit 73,000 tons of sulfur dioxide and 27,000 tons of nitrogen oxide per year, as well as other pollutants such as mercury.

Still, nuclear power does not produce the dirty emissions of coal - fired power plants, including soot, mercury and sulfur dioxide.

Rights - of - way on public lands result in landscape and habitat fragmentation, while coal combustion produces a number of gaseous byproducts, including CO2, nitrogen dioxide, sulfur dioxide, and methane — which exacerbate climate change and are associated with ground - level ozone (smog), air pollution, and acid rain.

True, if you look at it strictly from the point of view smog - producing chemicals like sulfur dioxide, new coal plants are cleaner than the old coal burners of yore.
