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

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...

UD's long-term monitoring shows 60 percent reduction in acidity of Delaware rain Several decades ago, precipitation in Delaware was among the most acidic in the country. Pollutants in the air reacted with rainwater to sprinkle sulfuric, nitric and carbonic acids onto the ground below, affecting crops and ecosystems statewide. The scientific consensus is that pollution controls enacted through the Clean Air Act Amendments in the 1990s and other measures have helped decrease the acidity...

Image 1 - Nitrogen From Humans Pollutes Remote Lakes

Nitrogen derived from human activities has polluted lakes throughout the Northern Hemisphere for more than a century and the fingerprint of these changes is evident even in remote lakes located thousands of miles from the nearest city, industrial area or farm. The findings, published in the journal Science Dec. 16, are based on historical changes in the chemical composition of bottom deposits in 36 lakes using an approach similar to aquatic archeology. More than three quarters of the...

The number of sugar maples in Upper Great Lakes forests is likely to decline in coming decades, according to University of Michigan ecologists and their colleagues, due to a previously unrecognized threat from a familiar enemy: acid rain. Over the past four decades, sugar maple abundance has declined in some regions of the northeastern United States and southeastern Canada, due largely to acidification of calcium-poor granitic soils in response to acid rain. Sugar maple forests in the...

New Effect Of Acid Rain On Forests
2011-12-09 03:49:42

Too Many Dead Leaves a Bad Sign for Sugar Maples Scientists have discovered that nitrogen that falls from the atmosphere in acid rain can influence large tracts of sugar maples in North America. The atmospheric nitrogen in acid rain can affect forest ecosystems by acidifying soils and causing nutrient imbalances. Sugar maples in northeastern North America are especially vulnerable. Vast maple areas have been affected by this acidification process, which depletes soil calcium in...

Image 1 - Aura Confirms Sharp Decline In US Pollution From Coal Power Plants
2011-12-02 04:48:03

A team of scientists have used the Ozone Monitoring Instrument (OMI) on NASA's Aura satellite to confirm major reductions in the levels of a key air pollutant generated by coal power plants in the eastern United States. The pollutant, sulfur dioxide, contributes to the formation of acid rain and can cause serious health problems. The scientists, led by an Environment Canada researcher, have shown that sulfur dioxide levels in the vicinity of major coal power plants have fallen by nearly...

Emissions regulations do have an environmental impact, according to a long-term study of acidic rainfall by researchers at the University of Illinois. The National Atmospheric Deposition Program collects rainfall samples weekly from more than 250 stations across the United States and analyzes them for pollutants. The program recently released a report detailing trends in acidic rainfall frequency and concentration over 25 years, from 1984 to 2009. "This is the longest-term, widest-scale...

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...
