  • Maintenance To-Do: Coil Cleaning

    A coil-cleaning program should be an integral part of maintaining some kinds of process cooling equipment. Most people think of coil cleaning as a building or facility prepares to turn on the air-conditioners for another season. Admittedly, spring is a perfect time to put such cleaning and maintenance at the top of the to-do list. Condenser and evaporator coils are an integral part of HVAC ...

  • Dispersion models and air quality data for population exposure assessment to air pollution

    Evaluating the extent of exposure to chemicals in absence of continuous measurements of their concentration in air and direct measures of personal exposure is crucial for epidemiological studies. Dispersion models can be a useful tool for reproducing spatio-temporal distribution of contaminants emitted by a specific source. However, they cannot easily be applied to short-term epidemiological ...

  • The Use of Real-Time Air Quality Data in Daily Forecasting and Decision-Making

    The feature articles published in this month’s issue describe various near-realtime data resources and provide examples of how they are being used to facilitate air quality forecasting and daily decision-making. The articles reinforce the importance of making as much environmental data as possible available to the public in real time. The major national source of realtime air quality data is ...

  • Combination of measured and modelling data in air quality assessment in Spain

    This paper describes a methodology to combine measurements from air quality stations and estimates from the CHIMERE model for air quality assessment in Spain. The methodology consists of using linear regression and kriging interpolation to correct the model results, improving the fit to the observations. It was separately applied to rural and urban conditions, giving rise to maps for each case, ...

  • Air quality in Europe — 2011 report

    The present report provides an overview and analysis of air quality in Europe. The analysis covers up to 38 European countries (EEA-38) (1) and spans the two decades of data that countries have made officially available up to 2009. The evaluation of the status and trends of air quality is based on ambient air measurements and data on anthropogenic emissions and trends. Emissions of the main air ...

  • Air quality in Europe — 2012 report

    'Air pollution is bad for our health. It reduces human life expectancy by more than eight months on average and by more than two years in the most polluted cities and regions. Member States must comply with EU air quality standards quickly and reduce air pollutant emissions,' Janez Potočnik, EU Commissioner for the Environment (EU, 2010a). Emissions of air pollutants derive from almost all ...

  • 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 ...

  • Air quality in Europe — 2015 report

    Air pollution is both an environmental and a social problem, as it leads to a multitude of adverse effects on human health, ecosystems, the built environment and the climate. Air pollution poses the single largest environmental health risk in Europe today. Air pollutants are emitted from anthropogenic and natural sources; they may be transported or formed over long distances; and they may affect ...

  • A modelling system for air quality management

    To develop effective air quality management strategies at regional and urban levels requires the preparation of several actions belonging to different scientific areas and analysis of their complex interactions. A well-structured management system must be based on efficient tools that integrate diverse sets of information - emissions, traffic, meteorological variables and air quality data. ...

  • Air quality in Europe — 2013 report

    Air quality continues to be a very important issue for public health, the economy and the environment. Europe has significantly cut emissions of several air pollutants in recent decades, greatly reducing emissions and exposure to substances such as sulphur dioxide (SO2), carbon monoxide (CO), benzene (C6H6) and lead (Pb). Despite improvements over several decades, air pollution continues to ...

  • Air quality monitoring and assessment programme for Botswana

    An Air Pollution Monitoring and Surveillance Program (BAQMAP) is being developed, installed and tested for Botswana. The project is funded partly by NORAD and partly by the Botswana Government.  The project is undertaken in a co-operation between Norwegian Institute for Air Research (NILU) in Norway and Department of Mines (DoM) in Botswana. NILU shall provide professional assistance in the ...

  • Criteria for the assessment of air quality levels in homogeneous areas

    A methodology is proposed for the appraisal of the data to confront with air quality limits. The methodology assesses air quality levels on the basis of mean values calculated as an average of all data collected in homogeneous areas, from monitoring stations located in sites not conditioned from local sources emissions. The resulting value represents the air quality of the area better than a ...
