  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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. ...

  • 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 ...

  • 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 ...

  • 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 ...

    In a direct response to demand from organisations across the UK, Enviro Technology plc , the leading UK supplier of environmental monitoring instrumentation and systems, have launched the ‘Magee Aethalometer' - an instrument that provides ...

  • 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 ...

  • ABIH Reminds Industry and Workers about Potential Carbon Black Hazards

    Earlier this month, an explosion at an ink factory injured seven workers.  All seven were taken to a nearby hospital and three were later treated at a special medical center for first and second-degree burns. The event happened at a New Jersey plant that produces black newspaper ink that is made from carbon black and other materials.    The accident is reported to have taken ...

  • New Report Outlines Strategies to Increase Funding for Black Carbon Reduction

    Reducing black carbon emissions could prevent millions of premature deaths annually and play an important role in the global fight against climate change. Yet despite these benefits, an array of black carbon abatement measures that are technically within reach have not yet been financed and deployed to their full potential. A report released today by the Climate and ...

  • Carbon particles causing health concerns across California due to wildfires

    LA Testing has been busy providing carbon black and combustible by-product analysis at their laboratories to area residents and environmental professionals. California Governor Arnold Schwarzenegger reported on Sunday that 11 major wildfires were burning across the state creating risks to inhabitants and property in many parts of the state. The California wildfire tribulations are well-chronicled ...


  • Black Powder: A pipeline and processing problem

    A ferrous contaminant created by internal erosion and corrosion of carbon steel pipelines and operating equipment, black powder, causes many operational problems. Black powder which ranges from 100 + microns to sub-micron sizes, with the majority being ferrous (on average 80%) and silica (20%) causes many costly problems for the pipeline and processing industries. Problems such as: degrading of ...
