Current computer models may underestimate levels of ground-level ozone A team of scientists has, for the first time, completely characterized an important chemical reaction that is critical to the formation of ground-level ozone in urban areas. The team's results indicate that computer models may be underestimating ozone levels in urban areas during episodes of poor air quality (smoggy days) by as much as five to 10 percent. Ground level ozone poses significant health hazards to people,...

LONDON, October 29, 2010 /PRNewswire/ -- Global shipping is causing damage to the marine environment estimated at EUR13 billion ($18 billion) annually, according to environmental charity The Going Blue Foundation. This is the first time a cost has been attributed to the reparation expense of all pollution caused solely by commercial shipping and cruises. The figure was arrived at using the Acquatrail formula(c) devised by Marine Positive. Marine Positive advises municipalities and...

Eutrophication of the Baltic Sea has clear negative effects, such as dead bottoms and massive blooms of cyanobacteria. But high plankton production can also have positive effects on acidification. Researchers at the University of Gothenburg, Sweden, have shown that it is possible to work out the aggregate effects of various environmental measures. "The environmental state of the Baltic Sea is affected by many different processes at the same time and on several different time scales....

Reducing the runoff from plant nutrients that can eventually wash into the Chesapeake Bay could someday be as easy as checking the weather forecast, thanks in part to work by U.S. Department of Agriculture (USDA) scientists. One way farmers manage manure from their livestock is by applying it to crop fields, which increases soil levels of nitrogen and phosphorus. But when it rains, the nitrogen and phosphorus in freshly applied manure is much more likely to run off and pollute nearby water...

On July 6 this summer, Virginia's Department of Environmental Quality issued the region's first "unhealthy" air alert since 2008.The culprit? "Bad" ozone and other air pollution that had combined to produce an abnormally high reading of 119 parts per billion in Suffolk and 70-80 parts per billion in other parts of southeastern Virginia. That compares to the natural concentration of ozone of about 10 parts per billion that was the norm more than a century ago.Ozone spikes are part of a pattern...

KIT Scientists Disprove Doubts in Ozone Hole Chemistry For the first time, KIT scientists have successfully measured in the ozone layer the chlorine compound ClOOCl which plays an important role in stratospheric ozone depletion. The doubts in the established models of polar ozone chemistry expressed by American researchers based on laboratory measurements are disproved by these new atmospheric observations. The established role played by chlorine compounds in atmospheric ozone chemistry is in...

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...
