Acid Rain - What Is Acid Rain?, Factors Affecting Acid Deposition, Sources Of Sulfate And Nitrate Inthe AtmosphereAdditional TopicsAcid Rain - What Is Acid Rain?Sulfur dioxide and nitrogen oxides are gases that occur naturally in the Earth's atmosphere. These gases react with water, oxygen, and other chemicals in the atmosphere to form various acidic compounds, including mild sulfuric acid and nitric acid. In nature, the combination of rain and these oxides is part of a natural balance that nourishes plants and aquatic life. However, when human act… Acid Rain - Factors Affecting Acid DepositionThe interplay of soil, water, climate, and winds can have a profound impact on the effects of acid deposition. The effects of acid rain can be greatly reduced by the presence of alkali (basic) substances. Sodium, potassium, magnesium, calcium, and bicarbonate are examples of chemicals with buffering (neutralizing) capacity. In areas where soils contain limestone (calcium carbonate) or other minera… Acid Rain - Sources Of Sulfate And Nitrate Inthe AtmosphereNatural causes of sulfate (sulfur oxides) in the atmosphere include ocean spray, volcanic emissions, and readily oxidized hydrogen sulfide released from the decomposition of organic matter found on land and in water. Natural sources of nitrogen or nitrates include nitrogen oxides produced by microorganisms in soils, by lightning during thunderstorms, and by forest fires. Scientists believe that on… Acid Rain - Effects Of Acid Deposition Onliving OrganismsAn ecosystem is a particular environment and the biological organisms that live there. Ecosystems can be global or tiny. The plants and animals living within an ecosystem are interdependent. For example, frogs eat water insects. If the insects disappear because of acid deposition effects, the frogs may not thrive because part of their food supply has disappeared. Because of the many and varied int… Acid Rain - Other Effects Of Acid RainSulfates and nitrates in the air contribute to reduced visibility, which means that people cannot see clearly or as far through the air. The air looks "hazy." Sulfate particles account for 50% to 70% of the visibility reduction in the eastern United States. Visibility in the East was expected to improve by 30% by 2010 because of acid rain program controls. The EPA has projected that … Acid Rain - Politics Of Acid RainThe early acid rain debate centered almost exclusively on the eastern portion of the United States and Canada. The controversy was often defined as a problem of property rights. The highly valued production of electricity in coal-fired utilities in the Ohio River Valley caused acid rain to fall on land in the Northeast and Canada. An important part of the acid rain controversy in the 1980s was the… Acid Rain - Are Efforts To Reduceacid Rain Working?During the years since the enactment of the Acid Rain Program, much progress has been made in reducing power plant emissions across the nation, particularly in the Ohio Valley and the Northeast, where emissions have been historically highest. Figure 9.6 shows the average sulfur dioxide emissions from power plants by state for the year 1990 and for the two phases of the Program. Figure 9.7 and Figu… Citing this materialPlease include a link to this page if you have found this material useful for research or writing a related article.
