  • Black Carbon – the elephant in the room!

    Traditionally, ambient particulates have been measured gravimetrically according to their size. However, in this article Jim Mills, Managing Director of Air Monitors, will demonstrate that the time has come to change or at least augment the way ambient particulates are monitored and regulated. Air Monitors has supplied most of the UK's ambient monitoring network, but Jim will explain why the ...

  • The Rationale for Accelerating Regionally Focused Climate Intervention Research

    Abstract Ten years ago, Paul Crutzen asked whether the time had come to consider undertaking research into intentionally intervening in the climate system so that it might be considered a policy option comparable to reducing emissions for limiting human-induced climate change. Crutzen’s article pointed out how little progress had been made in reducing emissions and suggested that ...

  • Status of black carbon monitoring in ambient air in Europe

    Black carbon (BC) is increasingly discussed in science and environmental policy areas as an example of an air pollutant that affects both human health and contributes to climate change (e.g. WHO, 2012; UNEP/WMO, 2011; Bond et al., 2013; IPCC, 2013). In order to be able to make comparable measurements of BC in ambient air and to relate BC monitoring to health impacts and climate change it is ...

  • NGO black carbon letter to environment ministers

    Dear Arctic Environment Ministers, We, the undersigned non-governmental organizations, write to urge you to use the occasion of the historic second meeting of Arctic environment ministers to strongly encourage Arctic states to take significant action to reduce emissions of black carbon. Last year the Arctic experienced record melting of both summer sea ice and the Greenland Ice Sheet and land ...

  • Solo flight tracks global Black Carbon

    On 8th January 2012 a tiny ultra-light aircraft left Ljubljana in Slovenia on a mission to circumvent the globe using the smallest amount of fuel per distance flown whilst recording ambient levels of Black Carbon (BC) – one of the most important measures of air quality in terms of both human health and climate change. UK based particulate monitoring specialist Jim Mills from Air Monitors ...

  • In-Vehicle exposures to particulate matter and black carbon

    ABSTRACTIn-vehicle exposures to particulate matter (PM) and black carbon (BC) can be a significant part of personal totalexposure. The purpose of this study was to identify determinants of the in-vehicle pollutant level. This study measured in-vehicle exposure to PM number concentrations using an aerosol spectrometer and BC concentration by an aethalometer. The measurement was repeated 3 ...

  • Black powder removal

    Black powder generally consists of various forms of iron sulfide or iron oxide, and is included with the other unwanted constituents such as water, liquid hydrocarbons and sand in natural gas and fluid transmission delivery systems. The ferrous contaminate, ranging from 10 microns to sub-micron sizes (finer than talcum powder), is created by the internal erosion/corrosion of the carbon steel used ...


  • Characterization of Polymer Carbon Sieves, Graphitized Polymer Carbons and Graphitized Carbon Blacks for Sample Preparation Applications

    The use of carbons in sample preparation techniques such as solid phase extraction (SPE) and air sampling has been ongoing for several decades. Recent advancements in sample preparation techniques have led to the use of carbons in micro-SPE (i.e., pipette tips packed with particles), solid phase microextraction (SPME) techniques and carbon coatings for both gas and liquid sample preparation ...

  • Influence of accidental fire on black carbon aerosol concentrations over an urban environment

    Carbonaceous aerosols are emitted by combustion sources and may influence the climate by altering the radiation balance of the atmosphere. Carbonaceous particles exist mainly in the accumulation mode and thus may be transported over long distances. The present study deals with the impact of anthropogenic activity associated with accidental fires on the black carbon aerosol concentrations over an ...

  • Black carbon emissions of individual cars measured under real conditions

    Measurements of individual vehicle emissions are usually made in laboratory tests. In this study, researchers followed cars driving in real conditions to measure emissions of air pollutants, including black carbon and nitrogen oxides. The study shows that diesel cars contribute disproportionately to air pollution, and highlights the value of on-road measurements. Vehicle traffic is a major source ...

  • Black Liquor – Green fuel or greenwash?

    Black liquor is not the product of a pot still in rural Tennessee, but a toxic by-product of the kraft wood pulping process. On May 20, 2009 Canada, together with the European Union, Brazil and Chile, wrote to the United States Congress urging them to repeal a tax credit for the use of black liquor as a biofuel on the basis that the credit is acting as a subsidy on the production of kraft pulp ...

  • Ruhr area sticks to black power

    Despite heavy opposition from environmentalists and scientists, brown coal continues to be the backbone of Germany’s energy supply. This will not change for some time to come, says German energy group RWE. ‘Environmental obstacles are surmountable. Some may consider it environmentally unfriendly and technologically outdated to extract and burn brown coal, but German energy company RWE Power begs ...

  • Reduced adsorption of propanil to black carbon: Effect of dissolved organic matter loading mode and molecule size

    In the present study, the reduced adsorption of propanil on black carbon (BC) influenced by dissolved organic matter (DOM) was verified to be closely related to DOM molecule size and loading mode. Two congenetic carbons, a rice‐residue–derived BC and the reduced product (RC), were characterized by similar specific surface area and different surface properties. Reduced product exhibits higher ...

  • Effect of carbon black nanoparticle on the morphology rheology and thermal properties of emulsion polymer blends

    In this study, the effects of the content of carbon black (CB) nanoparticle on the morphology of the emulsion polymer blends were investigated. The immiscible polymer blend was prepared with polystyrene (PS) and polypropylene (PP) in the absence and presence of different contents of CB nanoparticle in a twin screw mini extruder. The blend morphology was determined by Scanning Electron Microscopy ...

  • Thermal conductivity and stability of nanosize carbon-black-filled PDMS: fuel cell perspective

    Carbon black filled polydimethylsiloxane (PDMS) was considered as a prospective bipolar plate material candidate for a fuel cell. In this perspective, thermal conductivity and stability of the composites were investigated. Samples with filler weight fractions from 10% to 25% were prepared. The Thermal Gravimetric Analysis (TGA) study under oxygen atmosphere has shown good thermal stability of the ...

  • Buying time - reducing diesel black carbon offers an immediate opportunity for climate and public health benefits

    As delegates from countries around the world congregated in Copenhagen this past December to consider global action to combat climate change, they confronted a political, scientific, technical, and economic issue of unprecedented complexity and scope. To avoid the worst impacts of global warming, many scientists say we must guard against two related but different risks: (1) the cumulative warming ...

  • Carbotrap Carbon Black: An Excellent Adsorbent for Solvent or Thermal Desorption/GC Analyses of Airborne Organic Compounds

    Carbotrap adsorbent traps and releases a wider range of airborne organic compounds than Tenax GC or Amberlite XAD-2 resin. Compounds adsorbed by Carabotrap adsorbent can be completely recovered through either solvent or thermal desorption. Carbon disulfide, a highly effective desorbing solvent, degrades Tenax GC and Amberlite XAD-2, forcing you to use potentially less effective desorbing ...

  • Effects of subchronic inhalation exposure to carbon black nanoparticles in the nasal airways of laboratory rats

    The nose can be an efficient filter for inhaled gases, vapours and particles that may be harmful to the lung. Nasal airways may also be targets for injury caused by inhaled toxicants. To investigate the nasal toxicity of carbon black nanoparticles (CB), rats were exposed to 0, 1, 7 or 50 mg/m? of high surface area CB (HSCB; primary particle size 17 nm; particle surface area 300 m?/g) for 6 h/day, ...
