Acid rain is rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH).Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and ranges from 4–5 on average.
The Acid Rain Retirement Fund (A.R.R.F) is an all-volunteer, non-profit environmental educational organization, incorporated in Maine, dedicated to reducing pollution by purchasing and "retiring" marketable sulfur dioxide emissions allowances issued by the U.S. Environmental Protection Agency’s Acid Rain Program. A.R.R.F. was created in 1995 ...
Diagram depicting the sources and cycles of acid rain precipitation. Freshwater acidification occurs when acidic inputs enter a body of fresh water through the weathering of rocks, invasion of acidifying gas (e.g. carbon dioxide), or by the reduction of acid anions, like sulfate and nitrate within a lake, pond, or reservoir.

Two major causes of acid rain are sulphur dioxide and nitrogen oxide. [7] Acid rain can cause damage to soil, water, wildlife, plants and buildings. Additionally, the airborne particles that cause acid rain can also contribute to smog. [7] In recent years progress has been made in reducing acid rain, however, Alberta's oil sands may soon set ...
Sulfur dioxide causes acid rain, but it also produces sulfate aerosols in the atmosphere, which reflect sunlight and cause global dimming. After 1970, the increasing accumulation of greenhouse gases and controls on sulfur pollution led to a marked increase in temperature.
The entire state remains under a drought emergency declaration that Gov. Gavin Newsom issued in 2021, with millions of residents still under strict watering restrictions.
Every so often we hear horrifying stories of modern day cannibalism. In 2012, a naked man attacked and ate the face of a homeless man in Miami.That same year, a Brazilian trio killed a woman and ...
Robert Angus Smith FRS (15 February 1817 – 12 May 1884), commonly referred to as Angus Smith, [1] was a Scottish chemist, who investigated numerous environmental issues.He is known for his research on air pollution in 1852, in the course of which he discovered what came to be known as acid rain.
