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...

American Heart Association meeting report An early study in rats provides the first direct indication that a major component of smog might trigger cell death in the heart, researchers reported at the American Heart Association's Basic Cardiovascular Sciences 2010 Scientific Sessions "“ Technological and Conceptual Advances in Cardiovascular Disease. The study found that exposure to ground-level ozone over several weeks increased the activity of a substance that triggers cell death in...

Scientists find excess nitrogen favors plants that respond poorly to rising CO2 As atmospheric carbon dioxide levels rise, so does the pressure on the plant kingdom. The hope among policymakers, scientists and concerned citizens is that plants will absorb some of the extra CO2 and mitigate the impacts of climate change. For a few decades now, researchers have hypothesized about one major roadblock: nitrogen. Plants build their tissue primarily with the CO2 they take up from the atmosphere....

Human-driven changes in the earth's atmospheric composition are likely to alter plant diseases of the future. Researchers predict carbon dioxide will reach levels double those of the preindustrial era by the year 2050, complicating agriculture's need to produce enough food for a rapidly growing population. University of Illinois researchers are studying the impact of elevated carbon dioxide, elevated ozone and higher atmospheric temperatures on plant diseases that could challenge crops in...

HARRISBURG, Pa., June 3 /PRNewswire-USNewswire/ -- The Department of Environmental Protection and its regional air quality partnerships have forecast an air quality action day for Friday, June 4, in the Berks/Lehigh Valley, Susquehanna Valley and Philadelphia regions. Due to expected warmer temperatures and higher humidity levels, the air quality forecast predicts Friday will be code ORANGE for elevated ozone levels. The Berks/Lehigh region includes Berks, Lehigh and Northampton counties;...

Kudzu, an invasive vine that is spreading across the southeastern United States and northward, is a major contributor to large-scale increases of the pollutant surface ozone, according to a study published the week of May 17 in the journal Proceedings of the National Academy of Sciences. Kudzu, a leafy vine native to Japan and southeastern China, produces the chemicals isoprene and nitric oxide, which, when combined with nitrogen in the air, form ozone, an air pollutant that causes...

Choosing "greener" household cleaners, computers, and other consumer products could become as easy as reading a product's label thanks to a movement under way to develop universal guidelines for determining whether chemical products and chemical processes are environmentally friendly. That's the topic of an article in Chemical & Engineering News (C&EN), ACS' weekly newsmagazine. C&EN Senior Correspondent Stephen Ritter notes that chemical companies are eager to produce greener...

A new NASA study of Earth's polar ozone layer reinforces scientists' understanding of how human-produced chlorine chemicals involved in the destruction of ozone interact with each other. A team of scientists led by Michelle Santee of NASA's Jet Propulsion Laboratory, Pasadena, Calif., examined how nighttime temperatures affect chlorine monoxide, a key chemical involved in ozone destruction. Combining NASA satellite measurements with a state-of-the-art chemical model, they found this...

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...
