Question
b. A coastal city has only two major sources of sulfur, rain derived from the ocean and sulfur derived from a coal-burning power plant. A sample of city air yields ?34S = +14.0
2. The delta values for sulfur from different sources are (1) biogenic hydrogen sulfide = -2.0%0, (2) seawater sulfate = +20.0% and (3) sulfur in coal = +5.0%. Case Study 6-7 may be of use in solving this problem (attached) b. A coastal city has only two major sources of sulfur, rain derived from the ocean and sulfur derived from a coal-burning power plant. A sample of city air yields ?34S = +14.0?. Calculate the percent sulfur in the city air that is derived from the power plant.Explanation / Answer
This smoke comes from a coal-fired power plant and its pollutants include sulfur dioxide and the "greenhouse gas" carbon dioxide.Sulfur dioxide: Coal, petroleum, and other fuels are often impure and contain sulfur as well as organic (carbon-based) compounds. When sulfur (spelled "sulphur" in some countries) burns with oxygen from the air, sulfur dioxide (SO2) is produced. Coal-fired power plants are the world's biggest source of sulfur-dioxide air pollution, which contributes to smog, acid rain, and health problems that include lung disease.
