University of New Hampshire For more than 40 years, policy makers have been working to reduce acid rain, a serious environmental problem that can devastate lakes, streams, and forests and the plants and animals that live in these ecosystems. Now new research funded by the NH Agricultural Experiment Station (NHAES) at the University of New Hampshire College of Life Sciences and Agriculture indicates that lakes in New England and the Adirondack Mountains are recovering rapidly from the...

US Power Plant Emissions Down

University of Colorado at Boulder Power plants that use natural gas and a new technology to squeeze more energy from the fuel release far less of the greenhouse gas carbon dioxide than coal-fired power plants do, according to a new analysis accepted for publication Jan. 8 in Earth's Future, a journal of the American Geophysical Union. The so-called "combined cycle" natural gas power plants also release significantly less nitrogen oxides and sulfur dioxide, which can worsen air quality....

Ice Cores From Greenland Show Atmospheric Acidity

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...

Sulfur dioxide emissions from shipping have sharply decreased in EU ports thanks to an EU policy which limits sulfur content in fuels for ships at berth or at anchor in ports. Scientists at the European Commission's Joint Research Centre measured key air quality parameters in Mediterranean harbors before and after the entry into force of the low-sulfur requirements in January 2010. In European harbors they found an average decrease of 66% in concentrations of sulfur dioxide, a chemical...

Image 1 - Aura Confirms Sharp Decline In US Pollution From Coal Power Plants

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...

The federal government on Thursday announced the adoption of a new rule that will require Texas coal-fired power plants to cut pollution that worsens air quality in neighboring states.The announcement, coming from the Obama administration, will likely be met with sharp disapproval from Congressional Texans and some electricity companies in the Lone Star State, which say the Environmental Protection Agency (EPA) didn't give the state enough opportunity to explain why it should be exempt from...

KNOXVILLE, Tenn., Jan. 6, 2011 /PRNewswire-USNewswire/ -- A federal study shows Tennessee Valley Authority power plants have reduced emissions of two key acid rain components to a fraction of what was being released 30 years ago, and at a rate faster than the national average for the industry. (Logo: http://photos.prnewswire.com/prnh/20100304/TVALOGO) The study released Dec. 20 by the Environmental Protection Agency touted the success of the Acid Rain Program, designed to reduce...

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...
