Latest Soot Stories
Viewed as a potential target in the global effort to reduce climate change, atmospheric black carbon particles absorb significantly less sunlight than scientists predicted, raising new questions about the impact of black carbon on atmospheric warming, an international team of researchers, including climate chemists from Boston College.
For the first time, Lawrence Livermore researchers and international collaborators have peered into the makeup of complex airborne particulate matter so small that it can be transported into human lungs -- usually without a trace.
"For the first time we can actually see the structure of individual aerosol particles floating in air, their 'native habitat'," said DESY scientist Henry Chapman from the Center for Free-Electron Laser Science (CFEL) in Hamburg.
Laser probes microscopic components of air pollution
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.
People who cycle through London and other major cities have higher levels of black carbon in their airway cells.
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.
In some cases, soot â€“ the fine, black carbon silt that is released from stoves, cars and manufacturing plants â€“ can pack more of a climatic punch than greenhouse gases.
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.
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.
