Acid rain is comprised of water droplets that are strangely acidic as a result of atmospheric contamination, most strikingly the excessive amounts of sulfur and nitrogen discharged via vehicles and industrial procedures. Acid rain is additionally called acid deposition since this term incorporates different types of acidic precipitation, (for example, snow).
Today, acid deposition is available in the northeastern United States, southeastern Canada, and much of Europe, including parts of Sweden, Norway, and Germany. Likewise, portions of South Asia (especially China, Sri Lanka, and southern India) and South Africa are all in risk of being influenced by acid deposition later on.
Acid deposition can be brought about by natural sources, for example, volcanoes, yet it is for the most part brought about by the arrival of sulfur dioxide and nitrogen oxide during fossil fuel burning. At the point when these gases are released into the air, they respond with the water, oxygen, and different gases present there to create sulfuric acid, ammonium nitrate, and nitric acid. These acids at that point scatter over enormous regions due to wind patterns and fall back to the ground as acid rain or different types of precipitation.
The gases most respinsible for acid deposition are a byproduct of electric power production and the consuming of coal. In that capacity, man-made acid sdeposition started turning into a huge issue during the Industrial Revolution and was first found by a Scottish scientist Robert Angus Smith in 1852. In that year, he found the connection between acid rain and atmospheric contamination in Manchester, England.
Despite the fact that it was found during the 1800s, acid deposition didn't gain public attention until the 1960s, and the expression "acid rain" was formed in 1972. Public attention further expanded during the 1970s when the "New York Times" distributed reports about issues happening in the Hubbard Brook Experimental Forest in New Hampshire.
