black carbon measurement Articles

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 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 ...

  • 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 ...

  • Heterogeneous photo-catalysis system for the degradation of azo dye Reactive Black 5 (RB5)

    This study investigated a heterogeneous photo-catalysis system by introducing a novel brick supported iron oxide (denoted as B1) for the heterogeneous photoassisted degradation of Reactive Black 5 (RB5) at pH value from 3 to 7 in a three-phase (gas–liquid–solid) fluidized bed reactor (3P-FBR). Scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), X-ray powder diffraction ...

  • Why The Carbon Reduction Label For Wine?

     If you’ve continued to read past that title you are more than likely already familiar with terms such as: “climate change”, “carbon economy”, “global warming”, “carbon accounting”, “carbon neutrality”. I’m going to assume you have a passable understanding of the subject, issues and principles because ...

  • The “Social cost of carbon” and climate change policy

    Economist Frank Ackerman has called the “social cost of carbon” the most important number you never heard of. What is the social cost of carbon, where do the numbers come from, and why should policymakers take care when using them? The Obama Administration (and the Bush Administration before it) uses the SCC to assess the benefits of regulations that would limit emissions of carbon ...

  • Dangers of nanotechnology: potential fire concerns and safety frameworks

    The benefits of engineering of functional systems at the nanometre-scale as one of the key technologies of the 21st century almost always imply grave risks. The increasing speed of nanotechnology commercialisation and development has apparently outstripped the study of health and safety data. A potential hazard of nanopowders that appears to have received little attention so far is their ...

  • 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 ...

  • Aerosol characteristics at a continental urban station in southern India

    Spectral Aerosol Optical Depth (AOD), Black Carbon (BC) mass concentration and Suspended Particulate Matter (SPM) measurements were made at an urban continental location, Bangalore (13°N, 77.6°E), in southern India. These results show that AODs reach a maximum during April (∼0.5) and minimum during December (∼0.2) at 500 nm. BC and SPM showed variations of 0.6-4.2 μg m³ and 120-195 μg m³, ...

  • 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 ...

  • 2013: a ‘perfect storm’ in air quality

    As many countries fail to meet air quality targets and large numbers of premature deaths still result from air pollution, Jim Mills, a particulate monitoring specialist and Managing Director of Air Monitors, explains why 2013 will be a pivotal year. In November 2011 Janez Potočnik, European Commissioner for the Environment, expressed his determination to make 2013 the ‘Year of ...

  • Assessment of traffic congestion in Hong Kong, and prediction of street-level CO concentration using a graphical screening method

    The rapid growth in vehicle population and traffic volume in the past few years has offset the efforts of government to improve the poor traffic conditions in Hong Kong. This has intensified traffic congestion and hence the traffic-related pollution problems in the territory of Hong Kong, particularly in urban areas. Prediction was carried out using a simple graphical screening (SIMGS) method to ...

  • Eliminating Man-Made Hazein Protected Areas: A Goal of the Regional Haze Rule

    In recognition of the value of good visibility in areas set aside for their scenic splendor, Section 169A of the 1977 U.S. clean Air Act Amendments established a national goal of remedying existing visibility impairment and preventing future visibility impairment resulting from man-made air pollution emissions at 156 national parks and wilderness areas, referred to as visibility-protected federal ...
