  • Rajan Chakrabarty, assistant professor in the School of Engineering & Applied Science at Washington University in St. Louis, and William R. Heinson, a National Science Foundation postdoctoral fellow in Chakrabarty's lab, took on that challenge and discovered something new about soot, or rather, a new law that describes its ability to absorb light: the law of light absorption. (phys.org)
  • Chakrabarty and Heinson wanted to figure out a universal relationship between the amount of coating and the ability of soot to absorb light. (phys.org)
  • Black carbon also can absorb light reflected from Earth's surface, which helps make it such a potent warming agent. (wattsupwiththat.com)
  • Light-absorbing particles containing mainly black or elemental carbon absorb energy and are heated to the point of incandescence. (dropletmeasurement.com)
  • The 24-hour legal limit for particulate matter smaller than 2.5 microns, the most commonly used measure of soot, is 35 micrograms per cubic meter of air. (chicagotribune.com)

  • Black carbon from biomass combustion accounts for 1.6 million tonnes of CO2 in Norway, according to the study. (eurekalert.org)
  • On the other hand, residential heating from biomass has a carbon footprint of zero but has a non-negligible black carbon footprint. (forbes.com)
  • The formation and evolution of "brown carbon" (BrC, light-absorbing organic aerosol) was also examined, by measuring the optical properties of secondary organic aerosol (which under low-NO x conditions were shown to be only weakly absorbing) and examining how primary BrC (from biomass burning) evolves both chemically and optically. (epa.gov)
  • Biomass burning, a common method of clearing land and consuming farm waste, yields smoke that's comprised mainly of organic carbon and black carbon. (nasa.gov)
  • Soot particles are like tiny sponges that soak up toxic organic material and metals in fossil fuel and biomass burning. (nasa.gov)
  • Bond and her laboratory have characterized specific sources of black carbon at the local level in an array of remote locations, including cookstoves and kerosene lanterns, allowing for not only collection and analysis but also improved quantitative estimates of historical data. (macfound.org)
  • Common sources of Black Carbon that can cause residential or commercial property damage include candles, fuels such as oil, propane and natural gas used in gas appliances and gas log fireplaces, firewood burned in a fireplace or a wood-burning stove. (webwire.com)
  • Soot, also known as black carbon, is another concern for environmentalists. (storify.com)
  • The burning of firewood for heating, cooking, and other uses is the main source of soot particulates, known as 'black carbon,' that enter the air at levels 150 percent higher than the national standard and more than four times the World Health Organization's recommended limit. (worldwatch.org)
  • and soot, known as black carbon. (ff.org)
