  • Black carbon – the silent killer

    Black carbon - tiny particulate of soot created from the incomplete combustion of diesel fuels, cook stoves, some industrial processes, and from agricultural and forest burning. It can cause serious health issues and is a leading cause of childhood deaths in the developing world. Helping developing nations eliminate black carbon would be quick and easy, argued numerous scientists and experts that ...

  • A Tale of Two Cities' Black Carbon Measurement

    Advanced photoacoustic measurement of black carbon particles, using equipment available via UK-based Enviro Technology, has led to a better understanding of pollution in Los Angeles and Mexico City. PAX (Photoacoustic Extinctiometer) Black Carbon Monitors have been deployed to deliver a more accurate picture of daily black carbon trends in ...

  • CARBOTRAF – Black Carbon reduction by traffic management

    CARBOTRAF is a Seventh Framework Programme (FP7) of the European Commission. Lasting for three years, the project will study the relationship between traffic flow, Black Carbon (BC) emissions and carbon dioxide in urban environments. The project aims to create a method, system and tools for adaptively influencing traffic flow in real-time to reduce CO2 and BC emissions caused by road transport ...

  • Reducing Black Carbon Key to Protecting Arctic

    Sea ice loss and permafrost melt are self-amplifying feedbacks causing further warming. Arctic Ministers urge 'urgent action' to avoid irreversible global impacts    Arctic Environment Ministers are calling for "urgent action" to reduce black carbon, methane, and HFCs in order to help protect the Arctic and reduce the risk of setting off self-amplifying feedback mechanisms that ...

  • Black Carbon Emissions Cut 90% in California

    In a first-of-its kind study examining the impact black carbon has on climate in California, researchers found the state's efforts to reduce air pollution, particularly from diesel engines, has cut black carbon concentrations by 90% since 1966. This has happened without any noticeable disruption to the lives of the citizens of California, but with tremendous benefits to their health, as well as ...

  • Carbon Black Exposure May Put Workers at Risk

    Carbon black is the general term used to describe a powdery commercial form of carbon.  It is used by industry to strengthen and color rubber and is also used to color inks, coatings, plastics and leather, and to insulate electrical equipment.  Carbon black from vegetable origins is even used as a food coloring agent.    Some employees are exposed to carbon black on a regular ...

  • Air quality specialist calls for black carbon standard

    Traditionally, ambient particulates have been measured gravimetrically according to their size. However, Jim Mills, Managing Director of Air Monitors, believes that the time has come to change or at least augment the way ambient particulates are monitored and regulated. Black Carbon (BC) is a term describing the fine particles that are produced as the result of incomplete combustion of fuels and ...

  • Health and climate benefits by control of methane and black carbon

    Measures to control methane and black carbon (soot) emissions could improve air quality and public health, in addition to slowing the rate of climate change, according to recent research. By 2030, the reduced pollution could prevent between 700,000 and 4.7 million premature deaths each year, with 80% of the benefits occurring in Asia. Previous studies have linked the formation of ozone at ground ...

  • Black carbon a significant factor in melting of Himalayan glaciers

    The fact that glaciers in the Himalayan mountains are thinning is not disputed. However, few researchers have attempted to rigorously examine and quantify the causes. Lawrence Berkeley National Laboratory scientist Surabi Menon set out to isolate the impacts of the most commonly blamed culprit—greenhouse gases, such as carbon dioxide—from other particles in the air that may be causing the ...

  • Ontario’s dirty secret: black carbon and climate change

    To date, Ontario's policy responses to climate change have primarily focused on reducing carbon dioxide emissions from both the energy and transportation sectors or methane emissions from the waste and agricultural sectors. But scientific evidence points to opportunities presented by reducing emissions of short-lived climate forcers, principal among which is black carbon. Black carbon exists in ...

  • Reducing black carbon has immediate climate payoff

    Reducing emissions of black carbon soot and ground-level ozone would quickly make a considerable dent in the climate change problem and would also contribute to public health and protect crop yields, according to an essay in the September/October issue of Foreign Affairs. The piece was co-authored by Scripps Institution of Oceanography at UC San Diego climate and atmospheric scientist V. ...

  • Commitments Made to Reduce Black Carbon, Methane and Hydrofluorocarbons

    Governments and industry leaders in the Climate and Clean Air Coalition (CCAC) today committed to further essential advances in reducing short-lived climate pollutants (SLCP) that have a global warming potential many times that of the main greenhouse gas carbon dioxide. The SLCP Focus Day brought together some 30 Ministers and CEOs highlighting the importance and urgency of acting on ...

  • ASTM D3849 - 07(2011) Standard Test Method for Carbon Black—Morphological Characterization of Carbon Black Using Electron Microscopy

    Carbon black morphology significantly affects the transient and end-use properties of carbon black loaded polymer systems. A carbon black's particle size distribution is its single most important property, and it relates to degree of blackness and rubber reinforcement. For a given loading of carbon black, blackness and reinforcement increase with smaller particle size. Aggregate size and shape ...

  • Was Carbon Black a Factor in New Jersey Ink Plant Explosion?

    Last month, an explosion and fire at a manufacturing facility injured seven workers.  The event took place in East Rutherford, New Jersey, at plant that produces black newspaper ink. The workers were injured when a carbon compound used at the plant ignited.  Following the explosion, investigators from the Chemical Safety Board and Occupational Safety and Health Administration ...

  • IMO progress on black carbon in Arctic ‘welcome but long overdue’

    The decision at the International Maritime Organisation (IMO) to recommend to its environment committee a definition of black carbon arrived at by scientific consensus, after four years of debate, has been welcomed by environmental NGO Transport & Environment. Lack of agreement at sub-committee level had been holding up technical work to calibrate and test black carbon measurement methods ...

  • Black carbon pollution emerges as major player in global warming

    Soot from biomass burning, diesel exhaust has 60 percent of the effect of carbon dioxide on warming but mitigation offers immediate benefits.  Black carbon, a form of particulate air pollution most often produced from biomass burning, cooking with solid fuels and diesel exhaust, has a warming effect in the atmosphere three to four times greater than prevailing estimates, according to ...

  • EPA awards $6.6 million to universities for black carbon research

    "This research on black carbon will provide valuable information about the impact of black carbon on climate change," says William Sanders, director of EPA’s National Center for Environmental Research. “An increased understanding of the impact black carbon has on climate change will better protect people and the environment." EPA’s Science to Achieve Results (STAR) program ...

  • California’s Prop 65 and Public Health Concerns over Carbon Black

    In 1986, California voters approved an initiative to address increasing concerns over exposure to toxic chemicals. That initiative, the Safe Drinking Water and Toxic Enforcement Act of 1986, is better known by its original name of Proposition 65.  Proposition 65 requires businesses to notify Californians about significant amounts of chemicals in the products they purchase, in their homes ...

  • Black carbon ranked number two climate pollutant by US EPA

    The US Environmental Protection Agency concluded in a report to Congress that targeted strategies to reduce black carbon "can be expected to provide climate benefits within the next several decades," based on black carbon's strong warming potential and its short atmospheric lifetime of days to weeks.   EPA concluded that black carbon was likely to be causing more warming than any climate ...
