Laser probes microscopic components of air pollution Researchers at the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory have captured the most detailed images to date of airborne soot particles, a key contributor to global warming and a health hazard. The discovery reveals the particles' surprisingly complex nanostructures and could ultimately aid the understanding of atmospheric processes important to climate change, as well as the design of cleaner combustion...

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....

People who cycle through London and other major cities have higher levels of black carbon in their airway cells, experts from the UK have shown. The research, which will be presented at the European Respiratory Society's Annual Congress in Amsterdam today (25 September 2011), suggests that cyclists inhale more black carbon than pedestrians, which may cause damage to the lungs. The combustion of fossil fuels results in the generation of large numbers of inhalable particles of soot (black...

A new study of dust-like particles of soot in the air – now emerging as the second most important – but previously overlooked – factor in global warming provides fresh evidence that reducing soot emissions from diesel engines and other sources could slow melting of sea ice in the Arctic faster and more economically than any other quick fix, a scientist reported here today. In a presentation at the 242nd National Meeting & Exposition of the American Chemical Society...

Polluted snow causes early runoff, stronger monsoons in Asia In some cases, soot "“ the fine, black carbon silt that is released from stoves, cars and manufacturing plants "“ can pack more of a climatic punch than greenhouse gases, according to a paper published in the journal Atmospheric Chemistry and Physics. Researchers at the Department of Energy's Pacific Northwest National Laboratory, the University of Michigan and NOAA found that soot landing on snow on the massive Tibetan...

Soot from the burning of fossil fuels and solid biofuels contributes far more to global warming than has been thought, according to a new Stanford study.  But, unlike carbon dioxide, soot lingers only a few weeks in the atmosphere, so cutting emissions could have a significant and rapid impact on the climate. Controlling it may be the only option for saving the Arctic sea ice from melting. If soot emissions were eliminated, more than 1.5 million premature deaths from soot inhalation...

Action Also Needed to Cut Pollution Caused by Burning Dirtiest Heating Oils ALBANY, N.Y., June 23 /PRNewswire-USNewswire/ -- Environmental Defense Fund (EDF) praised the New York State Assembly for passing legislation today to dramatically reduce sulfur levels in the commonly used #2 heating oil sold in the state. The State Senate passed the legislation last week and Governor Paterson is expected to sign it into law. (Logo: http://www.newscom.com/cgi-bin/prnh/20100202/EDFLOGO) (Logo:...

RICHMOND, Va., June 7 /PRNewswire-USNewswire/ -- San Air Technologies Laboratory announced today that it now has the ability to detect "carbon black and soot" in the environment and confirm its presence using electron microscopy that magnifies objects by a factor of up to 100,000 times - a step that goes well beyond conventional scanning technologies. Carbon black and soot are the names insurance companies use to distinguish the dangerous microscopic particles within smoke from fires....

COLLEGE PARK, Md., April 30 /PRNewswire-USNewswire/ -- Anyone who has ridden behind a truck belching black exhaust knows the smell and discomfort caused by soot, the airborne carbon particles that result from the incomplete combustion of hydrocarbons such as diesel fuel. Those soot particles remain in the body beyond the moment of discomfort and can lead to lung diseases and other conditions. Peter Sunderland, assistant professor of fire protection engineering at the University of...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
