In a study that could solidify the trend toward construction of gigantic windmills, scientists have concluded that the larger the wind turbine, the greener the electricity it produces. Their report appears in ACS' journal Environmental Science & Technology. Marloes Caduff and colleagues point out that wind power is an increasingly popular source of electricity. It provides almost 2 percent of global electricity worldwide, a figure expected to approach 10 percent by 2020. The size of...

A new study eases concerns that irrigating crops with water released from sewage treatment plants – an increasingly common practice in arid areas of the world – fosters emergence of the antibiotic-resistant bacteria that cause thousands of serious infections each year. The research appears in ACS' journal Environmental Science & Technology. Eddie Cytryn and colleagues explain that a large fraction of antibiotics given to people or animals pass out of the body unchanged in...

With mold contamination of homes an ongoing concern — and a special threat to the 2.5 million foreclosed houses in the U.S., shuttered with little ventilation — scientists are reporting a new method to detect and identify low levels of airborne mold. The report, which describes a simple, fast method that could provide an early indication of potential contamination, appears in ACS' journal Environmental Science & Technology. Sutapa Ghosal and colleagues indicate that mold...

The hordes of bark beetles that have bored their way through more than 6 billion trees in the western U.S. and British Columbia since the 1990s do more than damage and kill stately pine, spruce and other trees. A new study finds that these pests can make trees release up to 20 times more of the organic substances that foster haze and air pollution in forested areas. It appears in ACS' journal Environmental Science & Technology. Kara Huff Hartz, Gannet Hallar and colleagues explain that...

A new study suggests that dumping old or unneeded medications in the trash can may be the best way to reduce the environmental impact of the 200 million pounds of pharmaceuticals that go unused in the U.S. each year. The report, which weighs the emissions from flushing, incinerating or trashing drugs, appears in ACS' journal Environmental Science & Technology. Stephen J. Skerlos and colleagues explain that to avoid the risks of abuse and accidental poisoning, as well as other problems...

Scientists from the University of Miami and Northern Illinois University develop guidelines to assess risk of illness from sand at recreational sites On warm days, the beach seems an ideal destination for family rest and relaxation. Who hasn't built a sand castle or been buried up to the neck in sand? However, that family fun has a dark side -- sand can harbor illness-causing microbes. Unfortunately, there are no guidelines for sand quality at recreational sites. Now, environmental...

With summer days at the beach on the minds of millions of winter-weary people, a new study provides health departments with information needed to determine when levels of disease-causing bacteria in beach sand could pose a risk to children and others who dig or play in the sand. The report appears in ACS' journal Environmental Science & Technology. Tomoyuki Shibata and Helena M. Solo-Gabriele explain that disease-causing bacteria from sewage can cause skin infections and...

The first real-world, head-to-head comparison of "improved cookstoves" (ICs) and traditional mud stoves has found that some ICs may at times emit more of the worrisome "black carbon," or soot, particles that are linked to serious health and environmental concerns than traditional mud stoves or open-cook fires. The report, which raises concerns about the leading hope as a clean cooking technology in the developing world, appears in ACS' journal Environmental Science &Technology....

New research has linked springtime die-offs of honeybees critical for pollinating food crops – part of the mysterious malady called colony collapse disorder – with technology for planting corn coated with insecticides. The study, published in ACS' journal Environmental Science & Technology, appears on the eve of spring planting seasons in some parts of Europe where farmers use the technology and widespread deaths of honeybees have occurred in the past. In the study, Andrea...

Modern technology depends on reliable supplies of a wide variety of materials, but there is increasing concern about the dependability of those supplies. In the first detailed assessment of metal "criticality," a team of undergraduates, master's students and research staff led by Thomas Graedel, the Clifton R. Musser Professor of Industrial Ecology, has codified a methodology that takes into account the risk of future scarcity and potential damage from shortages of metals in the periodic...
