Acid rain description

Acid rain is the popular term for a very complex environmental problem. Over the past 25 years, evidence has accumulated on changes in aquatic life and soil pH in Scandinavia, Canada, and the northeastern United States. Many believe that these changes are caused by acidic deposition traceable to pollutant acid precursors that result from the burning of fossil fuels. Acid rain is only one component of acidic deposition, a more appropriate description of this phenomenon. Acidic deposition is the combined total of wet and dry deposition, with wet acidic deposition being commonly referred to as acid rain. 

Description Sulfur dioxide (S02) is a gas resulting from the combustion of coal, mainly in power plants, and certain types of liquid fuels that contain sulfur. In addition, it is produced during the manufacture of paper and smelting of metals. It may cause respiratory problems and permanent damage to the lungs when inhaled at high levels. It plays a major role in the production of acid rain (EPA site). Carbon disulfide (CS2) has many industrial... 

Hotlines, either maintained by government agencies, universities, or organizations, offer a quick, useful resource for obtaining information or starting a path for further exploration. The hotlines here cover subjects from acid rain, air and asbestos to EPCRA and the Toxic Substances Control Act. A brief description of their contents and hours of operation are given. Use the hotlines to report emergencies, spills and other incidents that require instant notification and assistance. 

The emission of tropospheric sulphur oxide, and that of NO emission, is now of great concern, known colloquially, but inaccurately as acid rain . Acid deposition would be a better description of the phenomenon. 

One of the best present examples of the description of a toxic effect without much awareness or proof of tlie causality of the possible agents is the so-called acid rain wliich results in some Northern European countries in the acidification of poorly buffered soil and lakes, and to a decreased productivity in forest wood and lake-fisb. This toxic effect has been attributed to the acidity and mobility of aluminium salts resulting from the input of large quantities of SO ions in systems previously out of l each of pollutants from the dense industrial zones...

Plants were transferred to a special rain chamber and exposed to a simulated sulfate acid rain solution for one, 20 min period daily (except Tradescantia, 2 rainfalls daily). Descriptions of the chamber, the simulated rain solution, and the rain drop size distributions are given elsewhere (Evans, Gmur, and Da Costa, 1977). The pH levels of the simulated rain solutions were 5.7, 3.4, 3.1, 2.9, 2.7, 2.5, and 2.3. A plant was exposed to... 

Acid rain is an environmental issue that crosses state and national boundaries. Conduct library research on this topic and write a brief report. Include a description of the areas in the United States affected by acid rain, and the geographical source of the sulfur and nitrogen oxides that are responsible for acid rain in each region.
