In residential neighborhoods near manufacturing industries, a breath of air may be more hazardous than refreshing depending on the location, finds a recent study involving a Kansas State University geologist. Saugata Datta, assistant professor of geology at Kansas State University, along with researchers at Columbia University and Johns Hopkins Bloomberg School of Public Health and Department of Environmental Health Sciences, explored levels of the elemental metal manganese in airborne...

Dust Linked To Increased Glacier Melting, Ocean Productivity

[ Watch the Video ] Researchers analyze dust concentrations and their effects off southern Iceland A University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science-led study shows a link between large dust storms on Iceland and glacial melting. The dust is both accelerating glacial melting and contributing important nutrients to the surrounding North Atlantic Ocean. The results provide new insights on the role of dust in climate change and high-latitude ocean ecosystems....

Study Finds Space Dust Gives Asteroids Their Shape

Japanese researchers discovered while studying grains of dust from the Itokawa asteroid that tiny particles of space dust bombard asteroids and give them their shape. The researchers analyzed the size, mineralogy, shape and geochemistry of five dust grains recovered by the Japanese asteroid probe Hayabusa. Hayabusa succeeded in returning over 1,500 grains of dust from the asteroid Itokawa when it parachuted into the Australian outback in June 2010. "Our findings show the landscape...

With expanded industrial-scale production of nanomaterials fast approaching, scientists are reporting indications that dust generated during processing of nanomaterials may explode more easily than dust from wheat flour, cornstarch and most other common dust explosion hazards. Their article in ACS' journal Industrial & Engineering Chemistry Research indicates that nanomaterial dust could explode due to a spark with only 1/30th the energy needed to ignite sugar dust – the cause of...

Children living near coal-tar-sealed pavement are likely to receive a far higher dose of carcinogenic polycyclic aromatic hydrocarbons (PAHs) from incidental ingestion of house dust than do children living near unsealed pavement, and that dose is more than two times higher than the PAH dose children are estimated to receive from food. In a paper published in the journal Environmental Pollution, researchers at Baylor University in Waco, Texas, and the U.S. Geological Survey (USGS) in...

What would you do if you found out that the roads you drive on could cause cancer? This is the reality that residents face in Dunn County, North Dakota. For roughly 30 years, gravel containing the potentially carcinogenic mineral erionite was spread on nearly 500 kilometers of roads, playgrounds, parking lots, and even flower beds throughout Dunn County. Concerns about erionite were first unveiled in Central Anatolia, Turkey, where an epidemic of mesothelioma – a normally rare cancer...

A Kansas State University graduate student sees the unpaved road ahead, and it's filled with biomaterial. Wilson Smith, master's student in civil engineering, Independence, Mo., is working with lignin, a plant-based sustainable material that can be added to improve the quality of unpaved roads throughout Kansas. More than 70 percent of the 98,000 miles of roads in Kansas are unpaved, Smith said. "One of the problems with unpaved roads is that they are made from loose granular soils...

Some vacuum cleaners – those basic tools for maintaining a clean indoor environment in homes and offices – actually contribute to indoor air pollution by releasing into the air bacteria and dust that can spread infections and trigger allergies, researchers report in a new study. It appears in ACS' journal Environmental Science & Technology. Lidia Morawska and colleagues explain that previous studies showed that vacuum cleaners can increase levels of very small dust...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
