Where does most acid rain come from?
Causes of acid rain
The biggest sources are coal-burning power plants, factories, and automobiles. When humans burn fossil fuels, sulfur dioxide (SO2) and nitrogen oxides (NOx) are released into the atmosphere.
Why is there more acid rain in the Northeast?
The source of most sulfur dioxide is high-sulfur coal burned in power plants. Controlling this source of sulfur dioxide production can have a major impact on acid rain in Pennsylvania and other regions of the Northeast. Unfortunately, only 30 percent of the nitrogen oxides causing acid rain come from power production.
Why does Massachusetts have the most acid rain?
SO2 emissions are released from power plants that burn oil or coal to generate electricity and from industrial combustion of fossil fuels. … A substantial portion of acid deposition in Massachusetts can be attributed to SO2 and NOx emissions from out-of-state sources.
Is there acid rain in Massachusetts?
The average annual pH of precipitation in Massachusetts is near 4.2, approximately six times more acidic than uncontaminated precipitation. On every acre of land, 0.3 to 0.7 pounds of hydrogen ion, 16.2 to 27.5 pounds of sulfate and 8 to 22 pounds of nitrate falls per year as a result of acid precipitation.
Can acid rain burn your skin?
Very strong acids will burn if they touch your skin and can even destroy metals. Acid rain is much, much weaker than this; it is never acidic enough to burn your skin. Rain is always slightly acidic because it mixes with naturally occurring oxides in the air.
Where is acid rain?
It was not until the late 1960s and early 1970s, however, that acid rain was recognized as a regional environmental issue affecting large areas of western Europe and eastern North America. Acid rain also occurs in Asia and parts of Africa, South America, and Australia.
What has the United States done to reduce acid rain?
Regulations and new technologies are helping reduce acid rain. Power plants generate the electricity we use every day. Unfortunately, power plants also produce large amounts of nitrogen oxides and sulfur dioxide—the pollutants that cause acid rain—when they burn fossil fuels, especially coal, to produce energy.
