Major contributing gases for acid rain are sulfur dioxide (SO2), oxides of nitrogen (NOx), carbon dioxide (CO2) and chlorine (CI2). ... Carbon dioxide (CO2) reacts with water to form carbonic acid (HCO3-). ... Some other gases that are being released in the air are carbon dioxide, carbon monoxides, chlorofluorocarbons, hazardous air pollutants, lead, nitrogen oxides, ozone, particulate matter, sulfur dioxides, and volatile organic compounds. Carbon dioxide is released by burning coal, oil, and natural gas. ... This prevents the plant from taking in carbon dioxide to perform photosynthesis, ...

Carbon dioxide, which is emitted largely by combustion of fossil fuels, is the most influential human-made greenhouse gas. ... If emissions of carbon dioxide were halted today, it would take more than a century for the atmospheric level of carbon dioxide to approach its pre-industrial level. ... They feel that there is not sufficient evidence that human release of carbon dioxide, or any greenhouse gas, will have a devastating impact on the global climate. ...

The immense amounts of sulphur dioxide emitted into the air causes high levels of acid in the atmosphere. ... As with sulphur dioxide in rain, mercury is also discharged into the water. ... Acidic soil causes the carbon dioxide respiration process to decelerate. In order for plants to perform photosynthesis, they require carbon dioxide. ... The acid rain corrodes the thin, waxy layer, which coats and protects the leaves which in turn blocks the absorption of carbon dioxide and "suffocates" the leaves. ...

It was also found that cars were the main producer of the harmful chemicals, carbon monoxide or CO (91%) and nitric oxide or NO (82%). ... Carbon monoxide is the result of incomplete combustion of carbon containing materials, found in motor vehicles. It has the ability to react with other naturally occurring gasses in the atmosphere to form the most commonly known greenhouse gas carbon dioxide. The greenhouse effect is the term referring to the suns heat being trapped within our atmosphere by being absorbed by greenhouse gasses just like carbon dioxide. ... Estimates show that for just one per...

Carbon dioxide, nitrous oxide, and methane (CH4) are produced by the burning of fossil fuels, expelled from living and dead biomass, and released by the metabolic processes of microorganisms in the soil, wetlands, and oceans of our planet. ... These gases may have consisted of hydrogen (H2), water vapor, methane (CH4) , and carbon oxides. Prior to 3.5 billion years ago the atmosphere probably consisted of carbon dioxide (CO2), carbon monoxide (CO), water (H2O), nitrogen (N2), and hydrogen. ...

Historically regulated by the Clean Air Act, Sulfur Dioxide (SO2) combines with other elements in the atmosphere to form sulfate aerosols that can be inhaled. ... The Title IV Clean Air Act Amendment of 1990 set forth a primary goal to reduce Sulfur Dioxide emissions by 10 million tons below levels set for 1980. ... The British firm Tesco is offering a "Trees for Petrol" program which contributes 1.5p (pounds) to the Carbon Storage Trust. The non-profit organization will use the funds to plant forests that absorb the carbon dioxide from incomplete fuel combustion. Excess carbon dioxide in ...

"By far the most common cause of acid rain is sulphur dioxide, which is believed to cause 70 percent of acid rain, with various oxides of Nitrogen (NOX) causing the remaining 30 percent"(4). ... This study explains that Congress had made amendments to the Clean Air Act in 1990, that was supposed to cut the sulfur dioxide and nitrogen oxide emissions in half in coal-fired power plants and other industries(2). ... By reacting sulfur dioxide with calcium oxide to form calcium sulfite is a way of preventing escape of sulfur dioxide form industrial operations. ... Calcium Carbonate can also react w...

The acidity of rain is determined by the pH of pure water in reaction with atmospheric concentrations of carbon dioxide, resulting in carbonic acid. ... A bicarbonate atom is an ion formed by one hydrogen atom, one carbon at atom, and three oxygen atoms, and is very effective in natural waters at neutralizing hydrogen ions and reducing acidity. ... Rain less than 5.7 is considered 'acid rain', meaning it has reacted with acidic atmospheric gases other than carbon dioxide, such as sulfur dioxide and nitrogen dioxide. ...

Unpolluted rainfall is slightly acidic, with a natural pH of about 5, due to naturally occurring constituents of the atmosphere, such as carbon dioxide, but acid rain has a pH of about 4. ... Since passage (1970) of the Clean Air Act, U.S. emissions of sulfur dioxide have been reduced substantially, due to the burning of low-sulfur oil and coal, installation of costly scrubbers in smokestacks (see smoke) and electric plants, use of pollution controls by metal processors, reduction of diesel-fuel sulfur contents, and the installation of catalytic converters to clean automobile exhausts. ...
