Black Carbon (Soot) Monitoring Articles

  • Techniques for Soot in Oil Analysis

    Since no engine is 100% efficient, products other than carbon dioxide and water will be formed during combustion. One such product produced from incomplete combustion is soot. Soot is a mass of mainly carbon particles that are typically spherical in shape. As soot levels rise, the soot particles begin to clump together and ...

  • 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 ...

  • Messing with the monsoon: Study: Manmade aerosols can alter rainfall in the world’s most populous region

    Original story at MIT  On the Indian subcontinent, the widespread burning of firewood, coal, agricultural waste, and biomass for energy disperses black carbon particulates into the atmosphere. These manmade aerosols not only pollute the air, but also form an “atmospheric brown cloud” that’s disrupting the local ...

  • Modelling dispersion of smoke from wildfires in a Mediterranean area

    We present a modelling system for the estimation of forest fire emissions ( prebolchem-fire ) and their inclusion in the atmospheric composition model BOLCHEM. Emission fluxes have been estimated following the methodology proposed by Seiler and Crutzen (1980) and using MODIS ‘burned area product’. Then they are modulated following the WRAP approach (WRAP, 2005). This approach is also used for ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Soot level – a diesel engine lube oil condemning limit

    While there is widespread disagreement on used-diesel oil condemning limits, it is well known that excessive soot in the lube oil causes abnormal valve and injection-train wear.  It can also increase exhaust emissions and clog filters.  Typically, the suggested limit for soot is in the neighborhood of 3% but can go much higher.  With the new ASTM Method D7686, truck, bus, ...

  • 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 ...

  • 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 ...

  • Variations in mass concentrations of airborne particulate matter over tropical urban environment

    Particulate matter (PM) is an important component of the air pollution that has adverse health effects, ecosystem damage and degraded visibility. We analysed the seasonal variations in PM loading from ground-based measurements of PM1.0 and PM2.5, Aerosol Optical Depth (AOD) Black Carbon (BC) aerosol over Hyderabad, India during January-June, 2006. The PM concentrations showed relatively higher ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Composition and textural properties of soot and study of their oxidative elimination by catalytic process

    Diesel soot and reference carbon black samples have been characterised by analysis of the organic compounds fraction and determination of textural characteristics (specific area). The potential to eliminate such carbonaceous particles has been investigated using a Cu/ZrO2 solid catalyst promoted by potassium additives. The reactivity of soot samples depends on the organic compounds content. In ...

  • 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 ...


  • 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 ...
