Water Quality Improvements Likely Using New Understanding of Ion Interaction
Scientists at the U.S. Department of Energy's Argonne National Laboratory have discovered new ways that ions interact with mineral surfaces in water, opening a door to new knowledge on how contaminants travel in the environment. The insight, published in today's issue of Physical Review Letters, leads to a better understanding of the factors that determine water quality.
Water – colorless, odorless and tasteless – may seem simple, but its interactions with minerals can be difficult to study. Ions, which range from nutrients such as calcium, to contaminants such as lead, are present in natural waters, but their transport is often limited by adsorption to mineral surfaces. more>>>

Los Alamos Research Team Identifies Replacements for Mercury and Lead in Primary Explosives
Four ground-breaking families of environmentally friendly primary explosives under development at Los Alamos National Laboratory are featured this week in the Proceedings of the National Academy of Sciences.
"The environmental contamination and the health risk to personnel caused by mercury and lead in primary explosives has been a problem for nearly 400 years, but our team's recent research identifies replacements that are stable, appropriately sensitive, and suitably explosive," said scientist My Hang Huynh, the lead researcher. more>>>

Report Warns of Rising Carbon Dioxide Threats to Marine Life
Worldwide emissions of carbon dioxide from fossil fuel burning are dramatically altering ocean chemistry and threatening marine organisms, including corals, that secrete skeletal structures and help support ocean biodiversity.
A report summarizes the known effects of increased atmospheric carbon dioxide on these organisms, known as marine calcifiers, and recommends future research for determining the extent of these impacts.
"It is clear that seawater chemistry will change in coming decades and centuries in ways that will dramatically alter marine life," says Joan Kleypas, the report's lead author and a scientist at the National Center for Atmospheric Research in Boulder, Colo. more>>>
Watershed Pollutants from Midwestern Farms Contribute To "Dead Zone" In Gulf of Mexico
Winter floods and spring downpours are washing large amounts of nutrients off Midwestern farms and into streams feeding the Mississippi River, according to new research led by Todd Royer, an assistant professor at the Indiana University School of Public and Environmental Affairs. These nutrients ultimately end up in the Gulf of Mexico, where they contribute to its oxygen-starved "dead zone."
The new study, "Timing of Riverine Export of Nitrate and Phosphorus from Agricultural Watersheds in Illinois: Implications for Reducing Nutrient Loading to the Mississippi River," is featured in the current issue of Environmental Science & Technology. more>>>
