  • Characterisation of Urban Runoff Pollution in Paris

    Abstract:Runoff was collected from 4 roofs, 3 courtyards and 6 streets on an experimental catchment in central Paris, and analysed for SS, VSS, COD, BODS, hydrocarbons, heavy metals both as regards dissolved and particles fractions. Whereas street runoff showed important SS, COD and hydrocarbon loads, roof runoff was noticeable for its high concentration of heavy metals... ...

  • An urban scale model for pollutant dispersion in Rome

    A Gaussian model software (Atmospheric Dispersion Model System?ADMS-Urban) is used to forecast the carbon monoxide concentrations in the Urban Boundary Layer (UBL) of the city of Rome, Italy. The simulations refer to 14 days during 2002. Two data set inputs were considered in order to evaluate the urban background concentration and the effects of the main roads surrounding the monitoring ...

  • Traffic pollution modelling in a complex urban street

    This study explores for the first time, the applicability of the Danish Operational Street Pollution Model (OSPM) in the city of Buenos Aires where street canyons are very irregular. The model is applied in an irregular and asymmetric street canyon of a five–lane avenue near a street intersection. Urban background concentrations estimated by the DAUMOD model are considered. Meteorological ...

  • Water quality assessment of a polluted urban river

    Urban rivers in Latin America are heavily impacted by human activities that affect their functions and services. This paper shows the results of a water quality assessment for the Reconquista River, the second most polluted urban river in Argentina. They allowed the identification of the main processes of transport of pollutants and the prioritisation of different areas of the basin for ...

  • Numerical model of urban aerodynamics and pollution dispersion

    For analysis of atmospheric processes in the urban environment, the microscale meteorological and dispersion model M2UE is suggested, which takes into account a complex character of aerodynamics in non-uniform urban relief. The three-dimensional version of the model includes a system of Reynolds equations, two-equation k-ε model of turbulence and the 'advection-diffusion' equation to simulate ...

  • Urban Runoff

    Urban runoff is surface runoff of rainwater created by urbanization. This runoff is a major source of water pollution in many parts of the ...

  • Controlling urban stormwater pollution by constructed wetlands: a Canadian perspective

    During the past 20 years, Constructed Stormwater Wetlands (CSWWs) have attained broad acceptance in Canada as effective measures for stormwater management. CSWWs are used mainly for improving stormwater quality by providing sufficient treatment volumes in shallow permanent pools. This leads to high requirements for land, which is one of the constraints on CSWWs use. Even though CSWWs perform less ...

  • Research Note: Air pollution challenges and solutions for China's urban transportation development

    China has experienced dramatic urbanisation and motorisation in the past 20 years. The phenomenal rise in the vehicle population in major cities has resulted in increased air pollution, traffic congestion and other 'wicked problems'. The Chinese government at all levels has made significant effort to control motor vehicle emissions, but vehicle population growth far outpaces their efforts, ...

  • Efficiencies of multilayer infiltration systems for the removal of urban runoff pollutants

    Current rates of urban development will result in water runoff becoming a major complication of urban water pollution. To address the worsening situation regarding water resource shortage and pollution, novel multilayer infiltration systems were designed and their effectiveness for removing pollutants in urban runoff tested experimentally. The multilayer infiltration systems effectively removed ...

  • Application of dispersion models for evaluating the influence of urban air pollution on human health

    The main objective of this study is to analyse quantitatively the influence of urban air pollution on the health of children, by (i) analysing the concentrations of pollutants in the atmosphere, (ii) analysing the indoor air concentrations, and (iii) conducting epidemiological surveys. The area considered is Espoo, the neighbouring city of Helsinki. We focus in particular on the influence of ...

  • Evaluation of urban pollution abatement strategies by a photochemical dispersion model

    High ozone levels are regularly reached during the summer period in Italian urban areas, indicating the need for a careful design of primary pollutants emission reduction strategies. In this perspective, the CALGRID-CALMET modelling system has been applied to the Milano metropolitan area and its suburbs, a very industrialised and populated region in the Po Valley. A simulation domain of 100 x 100 ...

  • Priority organic pollutants in the urban water cycle (Toulouse, France)

    Application of the European Water Framework Directive requires Member States to have better understanding of the quality of surface waters in order to improve knowledge of priority pollutants. Xenobiotics in urban receiving waters are an emerging concern. This study proposes a screening campaign of nine molecular species of xenobiotics in a separated sewer system. Five sites were investigated ...

  • Evaluation of statistical distributions to analyze the pollution of Cd and Pb in urban runoff

    Heavy metal pollution in urban runoff causes severe environmental damage. Identification of these pollutants and their statistical analysis is necessary to provide management guidelines. In this study, 45 continuous probability distribution functions were selected to fit the Cd and Pb data in the runoff events of an urban area during October 2014–May 2015. The sampling was conducted from the ...

  • Developmental impairment in Eurasian dipper nestlings exposed to urban stream pollutants

    Avian studies of endocrine disruption have focussed traditionally on reproductive impairment given that many environmental contaminants affect sex steroid hormones. There is also increasing interest in altered thyroid function, and associated early development, particularly in altricial species with extended developmental windows. Both types of effect are relevant under the complex pollutant ...

  • ADMS-Urban: an air quality management system for traffic, domestic and industrial pollution

    The new version of the Atmospheric Dispersion Modelling System for urban environments, ADMS-Urban, is based on the same up-to-date physics as the ADMS model, outlined briefly here in Section 2. The basic model has been the subject of extensive validation studies: as part of this series of European Harmonisation Workshops; sponsored by HMIP (Her Majesty's Inspectorate of Pollution, now part of the ...

  • Screening of organic pollutants in urban wastewater treatment plants and corresponding receiving waters

    There is a lack of knowledge in environmental pollution of the anthropogenic contaminants in wastewater and surface water. Several organic compounds merit special attention, because of their potential risk to the aquatic environment. Therefore, gas chromatography–mass spectrometry-based screening analyses were performed in order to identify anthropogenic organic contaminants and to reveal ...

  • Influence of the land use pattern on the concentrations and fluxes of priority pollutants in urban stormwater

    This paper presents the results of the concentrations (μg/L) and fluxes (g/ha) of priority substances in stormwater from three watersheds with different land use patterns (namely, residential, urban dense, high urban density). Samples were collected at the outlet of these watersheds. Thirteen chemical groups were investigated corresponding to 88 individual substances before treatment. Results ...

  • Evaluation of air pollution, local meteorology and urban public health

    The relationship between meteorological conditions and air pollution was assessed as a plausible explanation for respiratory health problems in Newark, New Jersey on the US east coast. Pollutants in both particle (PM2.5 and PM10) and gas phase (O3) were collected and analysed. We find that PM2.5 concentrations decreased by -30.8% (95% CI: -43.2%, -15.8%) when the ...

  • Atmospheric chemical element pollution in an urban water-associated environment

    Nowadays, sustainability has become a complicated issue mainly in urban centres. Owing to the atmospheric emissions, the incorporation of toxic chemical elements is still not well known for urban water-associated ecosystems. Tillandsia bromeliads were employed as passive biomonitors of air pollution. Otherwise, the tank bromeliad Canistropsis billbergioides, native to the Atlantic Forest, was ...
