Soot from heaters and traffic is not just a local problem
aerosol particle soot climate change human health
2021/8/4
Soot particles from oil and wood heating systems as well as road traffic can pollute the air in Europe on a much larger scale than previously assumed. The evaluation of the sources during a measuring ...
The telltale signature of a cookstove, commonly used to prepare food or provide heat by burning wood, charcoal, animal dung or crop residue, is the thick, sooty smoke that rises from the flames. Its r...
Soot may be half the problem when it comes to cookstoves（图）

The telltale signature of a cookstove, commonly used to prepare food or provide heat by burning wood, charcoal, animal dung or crop residue, is the thick, sooty smoke that rises from the flames. Its r...
Research shows Antarctic lakes are a repository for ancient soot
Antarctic lakes repository ancient soot
2016/6/12
Remote lakes in a perpetually ice-free area of Antarctica show not only the chemical signature of ancient wildfires, but also some much more recent evidence of fossil-fuel combustion, according to Nat...
Arctic snow not darkening due to soot,dust,Dartmouth-led study finds
Arctic snow soot dust Dartmouth-led
2015/11/12
For millennia, Greenland's ice sheet reflected sunlight back into space, but satellite measurements in recent years suggest the bright surface is darkening, causing solar heat to be absorbed and surfa...
Carbon soot particles, dust blamed for discoloring India’s Taj Mahal
Carbon soot particles dust blamed discoloring India Taj Mahal
2014/12/30
Knowing the culprits in the discoloration is just the first step in cleaning up the Taj Mahal. Scientists now must determine where the particles are coming from to develop strategies for controlling t...
Impact of Simulated Airborne Soot on Maize Growth and Development
Black Carbon Maize Evapotranspiration Albedo Dry Matter Yield
2013/3/11
Various effects of the dry deposition of soot on maize were investigated in Keszthely (Hungary) in two consecutive years. In order to be able to study a wider range of weather conditions, some of the ...
Applying SEM-EDX and XRD Techniques to Demonstrate the Overgrowth of Atmospheric Soot and Its Coalescence with Crystal Silicate Particles in Delhi
Scanning Electron Microscope Energy Dispersive X-Ray Soot Aerosols Overgrowth Delhi
2013/2/26
Scanning electron microscopy-energy dispersive X-ray analysis (SEM-EDX) and X-ray diffraction (XRD) systems were used to demonstrate the overgrowth of soot to fractal like structure and its subsequent...
Characteristics of Atmospheric Elemental Carbon (Char and Soot) in Ultrafine and Fine Particles in a Roadside Environment, Japan
Black carbon (BC) Ultrafine particles Char-EC Soot-EC Diesel exhausts
2016/3/28
Atmospheric carbonaceous components, particularly char and soot in ultrafine particles (UFPs; Dp < 0.1 m) and fine
particles (FPs; Dp < 2.5 m), were measured four times during one...
Soot microphysical effects on liquid clouds, a multi-model investigation
carbonaceous aerosols liquid clouds a multi-model investigation
2011/2/25
We use global models to explore the microphysical effects of carbonaceous aerosols on liquid clouds. Although absorption of solar radiation by soot warms the atmosphere, soot may cause climate cooling...
Uptake of NO3 and N2O5 to Saharan dust, ambient urban aerosol and soot: a relative rate study
NO3 and N2O5 Saharan dust ambient urban aerosol and soot a relative rate study
2010/8/12
The uptake of NO3 and N2O5 to Saharan dust, ambient aerosols and soot was investigated using a novel and simple relative rate method with simultaneous detection of both NO3 and N2O5. The use of cavity...
