Antarctic Ozone Hole Smaller This Year
2013-10-26 05:52:20

[ Watch The Video: Daily Ozone Hole for 2013 ] redOrbit Staff & Wire Reports - Your Universe Online The Antarctic ozone hole, a seasonal phenomenon that starts forming during the month of August was slightly smaller this year than it was on average over the past several decades, NASA satellite data has revealed. The average size of the ozone hole in September-October 2013 was 8.1 million square miles (21 million square kilometers), the US space agency reported on Friday. In...

Researchers Demonstrate Effective Recycling Of Radicals During Isoprene Degradation
2013-10-07 07:02:51

Forschungszentrum Juelich Hydroxyl (OH) radicals – known as the detergent of the atmosphere – decompose isoprene in the air. This leads to the creation of new OH radicals, which are then able to purify the air of other pollutants and trace gases. The scientific community had previously only been able to speculate about this mechanism. The atmosphere has an astonishing ability to cleanse itself. Chemical processes ensure that trace gases and pollutants are removed from the atmosphere...

Plasmas attack bacterial cells on several levels RUB researchers analyse the mechanism of action of UV photons and radicals As they destroy bacteria very efficiently, plasmas constitute an alternative to chemical disinfectants and potentially to antibiotics, as well. How they achieve this effect has been investigated by biologists, plasma physicists and chemists at the Ruhr-Universität (RUB). Cold atmospheric-pressure plasmas attack the prokaryote’s cell envelope, proteins and DNA....

Surface Mining Environmental Cost
2013-09-12 10:02:17

Brett Smith for redOrbit.com - Your Universe Online To satiate the United States’ fierce appetite for coal, miners often utilize a tactic called surface mining, which involves stripping away rock and topsoil to access the fossil fuel below. According to a new report from researchers from Duke University just published in the journal PLOS ONE, coal retrieved from the Earth through surface mining comes at a significant cost to the ecosystem. Study researcher Brian D. Lutz, currently...

South Pacific Flights Make More Ozone
2013-09-05 15:12:27

Brett Smith for redOrbit.com - Your Universe Online A short-lived greenhouse gas, ozone’s formation and destruction depends mostly on the local chemical environment. Now, a new study from MIT researchers has indicated that flights passing over a certain section of the South Pacific produce the most ozone from their emissions. The results of the study, which was published in Environmental Research Letters, could have far-reaching implications for the timing and course taken by some...

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
2013-08-26 14:41:20

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...

NASA Study Finds Connection Between Population And Pollution
2013-08-20 14:33:41

Brett Smith for redOrbit.com - Your Universe Online While previous research has linked employment or innovation statistics to urban population density, a new study from NASA scientists has made a connection between pollution and the number of people living in a city. Using satellite observations, the NASA team was able to calculate air pollution's dependence on population for cities in the United States, Europe, China and India. According to the report, which was published in the...

Atlantis launched from Kennedy Space Center on November 3, 1994 at 11:59 AM EST and landed at Edwards AFB on November 14 at 7:33 AM PST. The shuttle orbited 174 times at an altitude of 164 nautical miles at an inclination of 57 degrees and travelled 4.5 million miles. The mission lasted 10 days, 22 hours, 34 minutes, and 2 seconds. This mission further advanced efforts to collect data about sun's energy output, chemical makeup of the Earth's middle atmosphere, and how these factors affect...

Today's soil contamination is a direct result of man-made chemicals or other changes in nature's soil environment. This contamination most commonly occurs from underground storage tanks bursting, use of pesticides, discarding oil and fuel illegally, leakage of dirty surface water, draining of wastes from landfalls and knowingly dumping industrial wastes into the soil. The most widespread chemicals found are petroleum hydrocarbons, solvents, common pesticides, lead and additional heavy metals....

Environmental science is a science that contains a wide range of scientific disciplines. These disciplines are grouped together based on the natural environment which they encompass and interact with. These sciences include physical, chemical, and biological components. Environmental science provides an interdisciplinary approach to the study of the environmental systems. The most common way environmental science is studied is through the work of one individual or small team drawing on the...
