  • States propose attainment designations for the new 1-hour So2 NAAQS

    The U.S. EPA revised the primary National Ambient Air Quality Standard (NAAQS) for sulfur dioxide (SO2) on June 2, 2010 by implementing a new 1-hour standard of 75 parts per billion (ppb) (calculated as the three-year average of the 99th percentile of the annual distribution of daily maximum 1-hour average concentrations). Based on an evaluation of the risks posed by acute exposure to SO2, EPA ...

  • Support to Aviation Control Service (SACS): an online service for near-real-time satellite monitoring of volcanic plumes

    Volcanic eruptions emit plumes of ash and gases into the atmosphere, potentially at very high altitudes. Ash-rich plumes are hazardous for airplanes as ash is very abrasive and easily melts inside their engines. With more than 50 active volcanoes per year and the ever-increasing number of commercial flights, the safety of airplanes is a real concern. Satellite measurements are ideal for ...

  • Modelling surface pollutant concentrations in the city of Zurich

    First results of a dispersion modelling study in the city of Zurich are presented. Surface pollutant concentrations (yearly averages) at several monitoring stations were modelled using the Danish OML-Multi operational model and compared with observations. For this purpose a detailed SO2 and NOx emission inventory for the year 1990 was constructed. The results show an average overestimation of the ...

  • Air pollution in Europe 1990-2004

    Overall picture This report analyses and presents changes in air pollutant emissions and their possible health or ecosystem impacts in Europe covering the period 1990–2004. Emissions of all air pollutants fell substantially during the period 1990–2004 in the 32 EEA member countries (EEA-32), resulting in improved air quality over the region. However, ambient concentrations of particulate ...

  • Study of Pollutants Dispersion in Complex Orography Area of Zakopane-Katowice-Krakow-Kielce

    This work is a summary of the activities and results obtained in the study of the pollutant dispersion over the Zakopane-Katowice-Krakow-Kielce area in complex orography. It is a component of WP4 (Air Quality Modelling), of the Krakow project “From toxic emissions to health effects: An integrated emissions, air quality and health impacts case study in Krakow, Poland”. This paper presents the ...


  • The impact of international shipping on European air quality and climate forcing

    Due to its dependence on fossil fuel combustion and the fact that it is one of the least regulated anthropogenic emission sources, emissions from the marine transport sector contribute significantly to air pollution and climate change. The main objective of this report is to provide a comprehensive review of recent literature and reports, taking into account expert knowledge, on the maritime ...

  • Annual European Community LRTAP Convention Emission Inventory 1990–2004

    1.1 Background information on the InventoryThe United Nations Economic Commission for Europe Convention on Long-range Transboundary Air Pollution (UNECE LRTAP Convention) was ratified (approved) by the European Community in 1982. Article 2 of the convention states that 'the Contracting Parties, taking due account of the facts and problems involved, are determined to protect man and his ...

  • Least-Cost Approaches to Reducing Acid Emissions

    ' The costs of meeting sulfur emission targets can be high. It is essential, therefore, that countries adopt policies which (a) minimize the net economic and social costs of reducing emissions to the agreed target levels, and (b) maximize the overlap between measures designed to reduce acidifying emissions and those addressing other forms of air pollution. This note discusses alternative ...

  • 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 ...

  • Total solution: Gas and particulate analysis in Cement industry

    Cement plants are increasingly required to install continuous emission monitoring systems (CEMS). While these represent a significant financial outlay, a range of other factors also need to be considered when selecting a suitable CEMS. To the inexperienced, selecting a suitable CEM can mistakenly be considered as simply ensuring that the applicable national regulations (eg MACT in the USA, ...
