Wetlands Could Be Key In Revitalizing Acid Streams
2013-09-05 10:28:37

University of Texas at Arlington A team of University of Texas at Arlington biologists working with the U.S. Geological Survey has found that watershed wetlands can serve as a natural source for the improvement of streams polluted by acid rain. The group, led by associate professor of biology Sophia Passy, also contends that recent increases in the level of organic matter in surface waters in regions of North America and Europe – also known as “brownification” – holds benefits...

Legacy Of Acid Rain Threatens Eastern US Water Supplies
2013-08-27 06:39:58

Cary Institute of Ecosystem Studies Human activities are changing the water chemistry of many streams and rivers in the Eastern U.S., with consequences for water supplies and aquatic life, so reports a new study in the journal Environmental Science and Technology. In the first survey of its kind, researchers looked at long-term alkalinity trends in 97 streams and rivers from Florida to New Hampshire. Sites ranged from small headwater streams to some of the nation's largest rivers. Over...

Eastern US Water Supplies Affected By Changing River Chemistry

University of Maryland 25+ years of records show two-thirds of region's rivers are now alkaline -- a legacy of acid rain, researchers say Human activities are changing the basic chemistry of many rivers in the Eastern U.S. in ways that have potentially major consequences for urban water supplies and aquatic ecosystems, a University of Maryland-led study has found. In the first survey of its kind, a research team looked at long-term records of alkalinity trends in 97 rivers from...

Freshwater fish and habitat will benefit from new Climate Action Plan, says the Atlantic Salmon Federation, through actions that promote switching fuel sources from coal to natural gas and renewables. St. Andrews, NB (PRWEB) June 28, 2013 Conservation groups concerned with the preservation and restoration of wild Atlantic salmon in both Canada and the United States can breathe a little easier this week, following President Obama’s announcement on Tuesday that he will unveil a new...

Decreased Water Flow May Allow For More Productive Forest
2013-03-25 16:22:39

Northern Research Station - USDA Forest Service Bubbling brooks and streams are a scenic and much loved feature of forest ecosystems, but long-term data at the U.S. Forest Service´s Hubbard Brook Experimental Forest suggests that more productive forests might carry considerably less water, according to a study published today in the journal Proceedings of the National Academy of Sciences. Mark Green, a research hydrologist with the Forest Service´s Northern Research Station...

Ice Cores From Greenland Show Atmospheric Acidity
2012-12-08 07:12:48

redOrbit Staff & Wire Reports - Your Universe Online Researchers from the University of Washington (UW) have linked decreasing levels of a nitrogen isotope in Greenland ice sheet samples to increased acidity levels in the atmosphere. Previously, the decrease in levels of the isotope nitrogen-15 had been linked to a correlating increase in nitrates linked with the burning of fossil fuels, the university explained in a December 7 report. However, the new research suggests sulfur...

Atmospheric Compound Linked To Climate Change, Human Health
2012-08-09 05:34:42

April Flowers for redOrbit.com - Your Universe Online An international team of researchers has discovered a surprising new chemical compound in Earth's atmosphere that reacts with sulfur dioxide to form sulfuric acid, which is known to have significant impacts on climate and health. The team, led by the University of Colorado Boulder and the University of Helsinki, found that the new compound, a type of carbonyl oxide, is formed from the reaction of ozone with alkenes. Alkenes are a...

Reign Of Acid Rain Is Far From Over
2012-07-26 05:46:01

New connection between climate change and acidification of Northeast's forests and streams Acid rain. It was a problem that largely affected U.S. eastern states. It began in the 1950s when Midwest coal plants spewed sulfur dioxide and nitrogen oxides into the air, turning clouds--and rainfall--acidic. As acid rain fell, it affected everything it touched, leaching calcium from soils and robbing plants of important nutrients. New England's sugar maples were among the trees left high and...

Acid Rain
2013-04-01 10:21:17

Acid rain is any form of precipitation that is unusually acidic, meaning that is possesses high levels of hydrogen ions. It can have harmful effects on aquatic animals, plants, and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules within the atmosphere to produce acids. Nitrogen oxides can be produced naturally by lightening strikes. Sulfur dioxide can be produced naturally by volcanic eruptions. The chemicals that are...

Rain is a type of liquid precipitation. It is defined as condensation of atmospheric water vapor that forms into drops that become heavy enough to fall, and often making it to the surface. Rain is the primary source of most of the fresh water in the world. Rain provides suitable conditions for diverse ecosystems, water for power sources and for crop irrigation. Not all rain reaches the surface. Some rain evaporates as it falls, especially through dry air. This type of rainfall is known as...
