  • Air quality indexing

    In an attempt to meet the public's needs for information on air quality a variety of indexes have been developed and they continue to evolve. To show the complexity and the diversity of such indices, a variety of current air quality indices are described here and compared in regard to their performance and ability to deliver quality information. A number of characteristics seem desirable for an ...

  • Reporting and exchanging air quality information using e-Reporting

    A number of EU legal instruments require EU Member States to monitor and report air quality data. This information is collated, analysed and disseminated by the European Environment Agency (EEA). At present much of the data is reported electronically by countries in data flows required under a specific legal instrument. As a result, reporting on air quality is not always integrated across all ...

  • Air Quality Monitoring

    Why monitor air quality? Well, to monitor is to know. Everything else is just more or less qualified guesses. International, national and local air quality targets and limits are also tied to monitoring results. What is Air Quality? How is air quality ...

  • Multiple Instruments Work Together for a Better View of Air Quality

    Accurately identifying and quantifying particulate matter (PM) in the atmosphere is key to determining air quality. Researchers are particularly interested in PM that have a diameter of less than 2.5 micrometers because they are believed to contribute to heart and lung disease in humans and animals. These tiny particles are invisible to the naked eye and originate from power plants, fires, and ...

  • Air quality modelling as a supplementary assessment method in the framework of the European Air Quality Directive

    According to the European Air Quality (AQ) Directive, member states must annually report their AQ to the European Commission (EC). This report can be based on modelling data if the concentration levels do not exceed the established lower assessment thresholds (LAT), or on combined data from modelling and monitoring systems (supplementary assessment methods) if concentrations levels are below the ...

  • The value of accurate air quality forecasts

    The value of accurate air quality forecasts critically depends upon how the information will be used. This paper proposes a simple model of private firm decision-making under uncertainty to consider potential economic applications and benefits from accurate air quality forecasts. It uses the findings of a survey of employees from five large employers in southern New Hampshire and northeastern ...

  • 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 ...

  • How clean is your local air?

    Few people know how clean the air is where they live, work, exercise or where their children go to school. Although air quality can be shown to vary significantly over short distances, air pollution is generally measured using a small number of large, expensive and high quality monitoring stations. The equipment used in these stations is very accurate and complies with measurement standards but ...

  • Study: Stem Cells and Air Quality

    A recent study conducted by researchers at the State Key Laboratory of Environmental Chemistry and Ecotoxicology, Research Center for Eco-Environmental Sciences China, Chinese Academy of Sciences (CAS), and the University of California at San Diego (UCSD) were successful in using stem cells to determine the amount of BPA that caused physiological toxic effects.  The group of ...

  • 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. ...

  • Chromatotec monitor air quality in Arcachon Bay through its own air quality station

    Chromatotec® made this summer the inauguration of its private monitoring station in Andernos-les-Bains. With a wealth of experience, thanks to which it already deployed massively its systems around the world, the group wanted to implement its own monitoring station to have complementary information to the actual air quality network. These data will allow the group to extend its ...

  • The ‘ins and outs’ of air quality monitoring

    The National Institute for Health and Care Excellence (NICE) recently issued draft guidance on ‘Air pollution - outdoor air quality and health.’ In the following article Jim Mills, Managing Director of Air Monitors Ltd, explains why there will need to be more funding for monitoring if the mitigation measures mentioned in the guidance are to be implemented effectively. Jim also ...

  • The Google Earth tool for studying Air Quality

    Any person involved in air quality studies knows that cartographic representation of data (input, output or measured) is very important, time consuming and, most often, difficult. One of the difficulties is to find a suitable cartographic base over which the information (sources, sensible receptors, buildings, isopleths, etc.) must be represented. Sometimes the cartographic base is available, but ...

  • Cartography for air quality monitoring: the geostatistical approach

    Being able to provide quick and accurate pollutant maps from readings at isolated measurement stations is becoming more important today in light of the European norms on air quality and the public’s demand to be informed. Commonly used algorithms for cartography are quick but their accuracy remains to be determined.Firstly, the choice of method is arbitrary and based on user’s subjective ...

  • Development of air quality indices for Mumbai, India

    This paper proposes a simple approach for developing air quality indices for different sites in an urban region of India. The database used for calculating these indices included various physical and chemical characteristics of suspended particulate matter, such as particle size distribution, chemical (elemental) properties and parameters governing the acidity of precipitation. The indices were ...

  • 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 ...

  • Ground Zero Air Quality Has A Long Way To Go! A Summary of Air Quality Testing in Surrounding Buildings

    There are still a wide range of concerns about air quality in the vicinity of Ground Zero. Many commercial and residential spaces have yet to be re-occupied. In only a few cases has any sort of inspection or testing been done to determine if they are safe to occupy. The greatest concerns are asbestos and the very irritating concrete dust that spread throughout lower Manhattan during the collapse ...

  • Confronting allegations of air quality non-compliance

    A facility with an air quality permit must comply with all the conditions of that permit and demonstrate its compliance on an on-going basis. Unfortunately, no matter how diligently the facility and corporate staff strives to assure continuous compliance, unexpected compliance challenges can occur. For example, new equipment fails the emissions guarantees provided by equipment vendors; new staff ...
