Can we use this remote perspective to identify our planet's pollution hot spots? (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) On Tuesday, Jan. 10, at NASA's Langley Research Center here, atmospheric chemist James Crawford will present, "Improving the View of Air Quality from Space," at 2 p.m. in the Reid Conference...

Image 1 - Nitrogen From Humans Pollutes Remote Lakes
2011-12-16 09:06:55

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...

Scientists are reporting development of a first-of-its-kind technology that could help law enforcement officials trace the residues from terrorist attacks involving nerve gas and other chemical agents back to the companies or other sources where the perpetrators obtained ingredients for the agent. A report on the technique, which could eventually help track down perpetrators of chemical attacks, appears in ACS' journal Analytical Chemistry. Carlos Fraga and colleagues explain that nerve...

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...

University of Iowa engineers have published their findings from a study of residential soils in the city of Cedar Rapids, making it one of only a few such U.S. urban soil studies ever conducted. The authors of the study, published in the November online edition of the journal Environmental Pollution, collected soils in the residential areas of downtown Cedar Rapids and analyzed them for industrial pollutants known as PCBs (polychlorinated biphyenyls) and chlordanes. Measured values for...

Researchers the world over are seeking reliable ways to predict earthquakes, focusing on identifying seismic precursors that, if detected early enough, could serve as early warnings. New research, published this week in the journal Applied Physics Letters, suggests that ozone gas emitted from fracturing rocks could serve as an indicator of impending earthquakes. Ozone is a natural gas, a byproduct of electrical discharges into the air from several sources, such as from lightning, or,...

HATBORO, Pa., Nov. 10, 2011 /PRNewswire/ -- Clean Earth, Inc. announced today the acquisition of privately owned Kleen Soil, located in Moore Haven, Florida. This facility treats non-hazardous petroleum-contaminated soils and will mark Clean Earth's seventh soil treatment and recycling location in the United States. This acquisition will provide Clean Earth the opportunity to geographically expand soil-recycling services and will be the most southern Clean Earth facility. Kleen Soil has...

Climate Change Disasters Cost US $14 Billion In Past Decade
2011-11-08 14:20:20

Researchers said on Monday that deaths and health problems from floods, drought and other U.S. disasters related to climate change cost $14 billion in the past decade. The study looked at the cost of human suffering and loss of life due to six disasters from 2000 through 2009. "When extreme weather hits, we hear about the property damage and insurance costs," Kim Knowlton, a senior scientist at the Natural Resources Defense Council and a co-author of the study, said in a statement. "The...

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...
