  • 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 ...

  • Baseline data in air quality impact studies

    The main objective of this paper is to explain not only the importance of the baseline data in air quality studies but also the general procedures and steps involved in the baseline data collection. Special considerations on the instruments and measurements for a perfect baseline data collection are also emphasized in this paper. As an example, an adequate baseline data collection procedure which ...

  • 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 ...

  • 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), ...

  • Model quality and safety studies

    The paper describes the EC initiative on model quality assessment and emphasises some of the problems encountered in the selection of data from field tests used in the evaluation process. Further, it discusses the impact of model uncertainties in safety studies of industrial plants. The model evaluation group (MEG) is a European initiative on evaluation of technical models used within the major ...

  • Urban Air Quality Management

    ' Poor air quality due to pollution is a serious environmental problem in most urban areas. The greatest burden of pollution is on human health. Urban air quality management requires an integrated approach that (i) identifies the most serious problems and measures that offer cost-effective and feasible solutions across a range of economic sectors and pollution sources including industries, ...

  • Uncertainty analysis of modelling studies included in air quality assessments

    This paper deals with the development of a quality analysis/quality control (QA/QC) methodology for modelling studies associated with air quality assessments. Among other benefits, this will allow data quality objectives for model input data to be derived and the importance of policy oriented model applications to be assessed. The procedure for evaluating model uncertainty has profited from a ...

  • Automotive parts coater exceeds local air quality requirements - Case Study

    Today many companies are faced with unique air pollution control problems arising from their coating operations. Not only are vented emissions required to be controlled, but now a more pressing issue is how to treat fugitive emissions. Fugitive emissions are the VOC and HAP releases that occur at the coating process or in a mixing area. Fugitive emissions are sometimes difficult to capture when ...

  • Air quality photochemical study over Amazonia Area, Brazil

    This work presents the results of a photochemical modelling system composed of MM5–SMOKE–CMAQ on Brazilian Amazonia area, been a pioneered implementation task. These results focus on the biogenic and biomass burning emissions and the impact of these emissions on regional air quality. Global and local anthropogenic emissions data, satellite–derived biomass burning inventories, ...

  • 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. ...

  • 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 ...

  • A quantitative approach to the traffic air quality problem: the traffic air quality index

    The Traffic Air Quality (TAQ) model is a simple tool to estimate traffic fine particulate emissions on roadways (g/km) and can be used for both real-time analysis and for localized conformity analysis (“hot-spot” analysis for nonattainment areas) as defined by 40 CFR 93.123. This paper is a follow-up to a study published earlier regarding the development of the TAQ model. This paper shows how ...

  • Vehicular Emission (Air Quality) Monitoring Study in Lagos, Nigeria

    INTRODUCTION On October 12, 2006 residents around Lagos Metropolis woke up, to their wonderment, to a hazy atmosphere which was very unusual to Lagosians and indeed to so many people. Many were lost as to what was happening. Some schools, especially around ...

  • 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 ...


  • An air quality modelling system for a medium-sized town: a case study in Estonia

    The air pollution modelling system used in Tartu (population 101,000) is aimed at examining the pollution levels in different meteorological conditions, and determining optimal traffic schemes and strategic development plans for the city. The system consists of: (i) a Gaussian plume model AEROPOL, and (ii) a database on sources of NOx2 ...
