  • 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 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 ...

  • 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 ...

  • 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 ...

  • 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, ...

  • Reasons for efficiency: Plain as the smudge on your face

    Remember soot? A long time ago, before global warming, getting rid of soot was considered a good reason to make our energy supply cleaner and more efficient. These small dirty particles, created from auto and power plant combustion, discolor walls and do worse to our lungs. Their harm is immediate, yet we seem to have forgotten this, as we’ve become consumed in energy debate about future worries. ...

  • 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 ...

  • Can roadway design air quality impacts

    In recent years, a consensus has emerged that exposure to traffic emissions increases risks of adverse health effects for populations living, working, or going to school near large roadways.1-4 Near-roadway air pollution is characterized by elevated levels of trafficgenerated compounds compared to overall urban background levels with the gradual decrease in concentrations within several hundred ...

  • 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 ...

  • WESPS continue to deliver

    Compliance with the increasingly stringent air pollution regulations of recent years is not the only reason forwardthinking industry leaders are adopting more sophisticated gas cleaning and air pollution control strategies. The desire to achieve higher performance efficiencies, control costs in a competitive marketplace, and stay ahead of the regulatory compliance curve is another driver of ...

  • 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 ...

  • Controlling scale deposits in the pulp & paper industry

    The pulp and paper industry is one of the heaviest users of water within the North American industrial economy, requiring on average 54 cubic meters of water per metric ton of finished product.  As water is used in nearly every part of the manufacturing process, accumulation of scale is a phenomenon that can occur in all pulp and paper making processes. This occurs even with the purest water ...

  • The Great Transition – Closing Coal Plants

    We may wake up one morning in the not-too-distant future and realize that the world has reached a tipping point on coal. So concludes the Earth Policy Institute in Chapter 3 of its upcoming report entitled The Great Transition: Shifting from Fossil Fuels to Solar and Wind Energy. Use of this fuel will be declining worldwide, as ...

  • Green Urban Infrastructure: Assessing Potential Ecosystem Services in Urban Cities

    Cities all over the world are currently experiencing climate change caused by rapidly increasing atmospheric greenhouse gases (GHGs). Fortunately, cities may mitigate GHG concentrations by incorporating vegetation into green urban infrastructure (GUI) to develop parks, green roofs, waterways, and other structures. For example, plants sequester carbon (C) by removing atmospheric ...

  • Air quality in Europe - 2014 report

    Despite considerable improvements in the past decades, Europe is still far from achieving levels of air quality that do not pose unacceptable risks to humans and the environment. Air pollution is the top environmental risk factor of premature death in Europe; it increases the incidence of a wide range of diseases and has several environmental impacts, damaging vegetation and ecosystems. This ...

  • Replacement of Two Separator /Absorber Units at an Acid Regeneration Plant

    If professional engineers were asked to define a perfect world, their answer would no doubt include projects that were blessed with a clear and precise description of the requirements, a viable schedule, availability of materials, and a reasonable amount of design freedom. Of course there is no perfect world, so engineers must work with restrictions that vary from difficult to almost impossible. ...
