Kansas State University researchers published a study in Frontiers in Environmental Science that showed Manganese relates differently than its cancer-causing cousin, arsenic, to dissolved organic matter in groundwater. Researchers say more studies are need to understand the relationship.
A warming climate is not just melting the Arctic's sea ice; it is stirring the remaining ice faster, increasing the odds that ice-rafted pollution will foul a neighboring country's waters, says a new study.
The technique enables the detection of gases, such as atmospheric pollutants, present in extremely small quantities that are otherwise difficult or impossible to detect.
The airborne dust carried in sand storms affects the health of people and ecosystems alike. New research at the Weizmann Institute of Science suggests that part of the effect might not be in the particles of dust but rather in bacteria that cling to them, traveling many kilometers in the air with the storms.
Biofuel policies like the Low-Carbon Fuel Standard in California are trying to minimize the indirect land use change related emissions by accounting for the indirect land use change factor as part of the carbon emissions per gallon of biofuels. A University of Illinois study examines the costs and benefits of using this approach at a national level.
A new analysis shows that septic systems in the United States routinely discharge pharmaceuticals, consumer product chemicals, and other potentially hazardous chemicals into the environment. The study is the most comprehensive assessment to date of septic systems as important sources of emerging contaminants, raising health concerns since many of these chemicals, once discharged, end up in groundwater and drinking water supplies.
Global solar energy production is taking a major hit due to air pollution and dust. The first study of its kind shows airborne particles and their accumulation on solar cells is cutting energy output by more than 25 percent in certain parts of the world. The regions hardest hit are also those investing the most in solar energy installations -- China, India and the Arabian Peninsula.
The Deepwater Horizon oil spill in the Gulf of Mexico in 2010 is one of the most studied spills in history, yet scientists haven't agreed on the role of microbes in eating up the oil. Now a research team at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has identified all of the principal oil-degrading bacteria as well as their mechanisms for chewing up the many different components that make up the released crude oil.
Exposure to ozone in the environment puts individuals with high levels of genetic variation at an even higher risk for developing autism than would be expected just by adding the two risk factors together, a new analysis shows. The study is the first to look at the combined effects of genome-wide genetic change and environmental risk factors for autism.
Researchers from the National Institute of Standards and Technology (NIST) and the University of Colorado Boulder have demonstrated a new mobile, ground-based system that could scan and map atmospheric gas plumes over kilometer distances.
