Course # Student name / Names of members of group Date: Exp # : Estimating the effects of acid rain Introduction: Precipitation that measures a pH value below 5.6 is generally considered as acid rain. Burning fossil fuels is the main reason for the elevated levels of gaseous oxides in a polluted atmosphere that in-turn forms acid rain. Gaseous oxides such as that of carbon, sulfur, nitrogen and phosphorus could dissolve in water to form an acidic solution. A generalized reaction sequence on the formation of acid rain is as follows; One of the determinants of clean water in the natural environment is its alkalinity. Alkalinity can be defined as the capacity to neutralize acids.
More animal species are becoming endangered or extinct as a result of global warming.” “The carbon emissions, pollution and human health problems that have resulted directly from the Industrial Revolution’s accomplishments have only been disastrous for the world environment. For example the increase of the production in the textile industry, iron and steel and the steam power. As a result, many people died cause of too much smoke spread in the air. Another example according to the reading, air and water pollution came from coal burning, as well as most stages in the production of metals and basic chemicals. Moreover, “The advent of the steam locomotive and railroad also saw the start of major pollution caused by big business, which is all too often seen today.
1b)Coal is a fossil fuel, which means when it is burnt it releases unwanted pollutants which have a negative and harmful impact on our environment. These pollutants are: Carbon Dioxide- This gas is considered to be the most harmful pollutant as it contributes to global warming. Coal is attributed to approximately 20% of the total pollution globally per year of all the fossil fuels. Sulfur emissions- when sulfur mixes with oxygen a harmful substance is formed. SO2, sulfur dioxide effects our trees and water systems and is the prominent cause of acid rain.
2013).Pharmaceutical companies sometimes place active chemicals and waste into groundwater sources, in which almost all of the groundwater may be untreated which most likely cause contamination. (Herber, 2002). Abstract: Increase in the emissions of carbon dioxide by burning fossil fuels is the largest cause of environmental down grading resulting not only in global warming but also causing acid rain which alters the pH balance of ground water. Water is a universal solvent; however, its dissolving properties are very sensitive to changes in temperature and pH. Global economic growth has, unfortunately,
Large amounts of methane and other poisonous gases released into the air from the gas wells contribute to heavy air pollution and global warming. Fracking has been linked to movement of radioactive materials and heavy metals from the underground layers of the earth to the surface through flow-back
Examine the environmental impact caused by the extraction process. From mining to coal cleaning, from transportation to electricity generation to disposal, coal releases toxic pollutants into our air, our waters and onto our lands. The impact of all of these effects is magnified by the enormous quantities of coal burned each year. The trace elements contained in coal are a large group of pollutants with a number of health and environmental effects. They are a public health concern because at sufficient exposure levels they adversely affect human health.
Effect of Local Steel Slag as a Coarse Aggregate on Properties of Fly Ash Based-Geopolymer Concrete O. M. Omar, A. M. Heniegal, G. D. Abd Elhameed, H. A. Mohamadien Abstract—Local steel slag is produced as a by-product during the oxidation of steel pellets in an electric arc furnace. Using local steel slag waste as a hundred substitutes of crushed stone in construction materials would resolve the environmental problems caused by the large-scale depletion of the natural sources of dolomite. This paper reports the experimental study to investigate the influence of a hundred replacement of dolomite as a coarse aggregate with local steel slag, on the fresh and hardened geopolymer concrete properties. The investigation includes traditional testing
Research question: Will the level of acidity of the rain have an effect on the corrosion of limestone, as measured by change in mass of marble chips in a beaker? Introduction: Acid rain is any form of precipitation due to excess or elevated levels of hydrogen ions. It is also a process by which acid particles leave the atmosphere. Natural rain has a pH of 5.6; this is due to the presence of carbonic acid by the mixture of carbon dioxide dissolved in water in the atmosphere. H2O + CO2 → H2CO3 The carbonic acid molecules immediately dissociate in water to form hydrogen carbonate ions: HCO3−, and hydronium ions, H3O+: H2CO3 + H2O → HCO3− + H3O+ The deposition of acid like sulfuric and sulfurous make rain water acidic this is from the sulfur
When humans burn fossil fuels, most of the carbon quickly enters the atmosphere as carbon dioxide. Carbon dioxide is a greenhouse gas and traps heat in the atmosphere. Without it and other greenhouse gases, Earth would be a frozen world. But humans have burned so much
Fossil fuels are fuels made of organic matter such as oil or coal. When these fossil fuels are burned they give off another green house gas called carbon dioxide. Now we look at the ways in which global warming damages the world we live in. Global warming, as mentioned above is the rise in the average temperature of the earth’s atmosphere. What does this rise in temperature actually do?
