  • Universal system for forecasting changes in PM10 and PM2.5 particulate matter air pollution concentration

    We present a system for forecasting the changes in PM 10 and PM 2.5 particulate matter air pollution concentration. The system is based on immissions data from automatic measurement stations of the Voivodship (Regional) Inspectorate for Environmental Protection in Warsaw (Poland) and a numerical forecast of meteorological parameters from the Interdisciplinary Centre for ...

  • Neptune Project Deliverable D1.2

    Several EU member states have yet to satisfy the stringent nutrient removal requirement of the Urban Waste Water Directive (1991) for sensitive areas. An environmental engineer working in the field of wastewater treatment is faced with increasing demands on the treatment efficiency. With the new European Water Framework Directive (EWFD, 2000/60/CE) there is a shift in paradigm from emission-based ...

  • An integrated approach for urban water quality assessment

    This paper introduces an integrated approach for the assessment of receiving water quality and the relative contribution of the urban drainage system to perceived receiving water quality problems. The approach combines mass balances with relatively simple receiving water impact models. The research project has learned that the urban drainage system is only one of the determining factors with ...

  • Emission standards versus immission standards for assessing the impact of urban drainage on ephemeral receiving water bodies

    In the past, emission standard indicators have been adopted by environmental regulation authorities in order to preserve the quality of a receiving water body. Such indicators are based on the frequency or magnitude of a polluted discharge that may be continuous or intermittent. In order to properly maintain the quality of receiving waters, the Water Framework Directive, following the basic ideas ...

  • A dataset for the validation of flow and dispersion models at an urban intersection

    Dispersion modelling concerning air pollution caused by road traffic is reduced to a two-dimensional problem within street canyons. However, significant pollution loads are also to be expected at intersections. In this case, three-dimensional flow and dispersion structures have to be considered. For the validation of models claimed to be applicable to intersections, measurements of meteorological ...

  • IFDM modelling for optimal siting of air quality monitoring stations around five oil refineries

    An IFDM modelling study has been conducted to determine the optimal siting of air quality monitoring stations around five oil refineries. The purpose of this immission monitoring network is specified in environmental legislation. The most appropriate output parameter of the IFDM model for this study is the 98th percentile of the moving 24 h averages, P98,m24h. Modelling for the optimal siting of ...
