  • 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 ...

  • Studies of air quality predictors based on neural networks

    In recent years, urban air pollution has emerged as an acute problem because of its negative effect on health and living conditions. Regional air quality problems, in general, are linked to violations of specified air quality standards. The current study aims to find neural network based air quality predictors, which can work with a limited number of datasets and are robust enough to handle data ...

  • Improving air quality in the office

    Most people spend the main part of their day indoors – in the home, school or office environment. Focusing specifically on improving air quality in the office and workplace setting, we are looking at the key potential sources of pollution which impact upon air quality and employees’ health. Examples include, outdoor air (particularly relevant if the workplace is next to a busy road), ...

  • Hyperion case study - UVC lights enhance air quality

    Located at the center of the Hyperion Wastewater Treatment Plant in Los Angeles, the Pregerson Building was experiencing indoor air quality (IAQ) problems. Built in 2002 to house nearly 400 city employees, the facility rapidly became the source of complaints about poor IAQ and odors. An engineered solution that incorporates both an odor control unit and supplemental ultraviolet- C (UVC) lights in ...


  • Indoor air quality in primary schools

    The indoor air quality (IAQ) in classrooms is expected to play a key role in the assessment of the effects of the children's personal exposure to air pollution since they spend on average 7–11 h per weekday at school. A statistical treatment was conducted over a database of indoor air parameters and the primary schools where these parameters were sampled (urban area of Lisbon, Portugal). The aim ...

  • Inter-comparison of two air quality modelling systems for a case study in Berlin

    A case study was carried out to compare two air-quality models (UAM-V and MCCM) in the region of Berlin. These are two well documented regional and urban models which were run independently with their own meteorological drivers and emission inventories with the aim to describe a specific ozone episode. Numerous applications in the US and in Europe have shown the good performance of these models. ...
