  • 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... ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Pollutant release from a disturbed urban snowpack in northern Sweden

    Water and pollutant release from a disturbed urban snowpack was studied in an experimental plot encompassing a road section and the adjacent grassed boulevard in the city of Luleå, in northern Sweden. Winter road maintenance in this area includes snow ploughing and applications of grit without any road salts. During the study period, 18 snowmelt events were observed. Compared to rural areas and ...

  • 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 ...

  • Urban Heat Island and Air Pollution—An Emerging Role for Hospital Respiratory Admissions in an Urban Area

    The aim of the study discussed here was to determine the associations among the urban heat island (UHI), air quality, and hospital respiratory admissions in the warm center of an urban area. The authors collected and analyzed the data regarding air quality parameters, meteorological parameters, and the daily hospital respiratory admissions in the Taichung metropolis in the autumns of 2003 and ...

  • Application of urban street canyon models for predicting vehicular pollution in an urban area in Dublin, Ireland

    The relative performance of two atmospheric dispersion models STREET and OSPM is assessed using measured CO and NOx data obtained adjacent to an urban street canyon. This paper in particular, evaluates the performance of STREET, a mathematical model, to determine its suitability as an alternative to the OSPM model, which is a more elaborate numerical model. ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Meteorology applied to urban air pollution problems: COST 715

    The requirements of the framework Directive on air quality assessment and management introduce real practical problems for the meteorological community. Some of the meteorological variables needed in urban air pollution assessments are not routinely measured and in normal circumstances the number of meteorological stations in urban areas is limited to a few sites, often just at airports. The ...

  • Economic impacts of urban air pollution: valuation for Mumbai, India

    Urban air pollution is on the rise in many cities of the world. There are associated health impacts that affect urban residents, especially the poor. By doing economic valuation, it is possible to draw the attention of citizens, policy-makers and, of course, researchers to the extent of damage and the value of it. In this paper, such a valuation is done using time-series data for the suburb of ...

  • Land-use-based sources of pollutants in urban storm water

     ABSTRACT Urban storm water is recognized as a major source of pollution to many of the nation’s waterways. However, little is known about the mechanisms and processes that influence pollutant loadings from specific land-use types. The goals of this study were (1) to examine event mean concentrations (EMC) and fluxes of TSS, metals, PAHs, and bacteria associated with storm water runoff ...
