  • Simulating organic pollutant flows in urban stormwater: development and evaluation of a model for nonylphenols and phthalates

    Stormwater-quality models can be useful tools for predicting pollutant loads and identifying sources of contamination. Most models in current use handle pollutants such as metals, nutrients and suspended solids, whereas models including emerging organic contaminants are rare. This study aims at developing and evaluating a model for simulating stormwater flows of two groups of organic pollutants; ...

  • Gaseous pollutant dispersion around urban-canopy elements: wind tunnel case studies

    There is an evident lack of reliable and detailed in situ measurement data for verifying numerical predictions of atmospheric dispersion in the urban environment on sub-meso scales. Wind-tunnel studies of dispersion around typical elements of the urban canopy (isolated buildings, groups of buildings, street canyons) could provide valuable substitutes for field datasets. They can achieve a high ...

  • Use and Validation of ADMS-Urban in contrasting Urban and Industrial Locations

    Throughout Europe there is increasing activity to assess and improve air quality in urban areas. In the UK this has beendriven by a National Air Quality Strategy which requires local government authorities e.g. towns and districts, tomanage air quality in their areas, with the aim of achieving the objectives laid out in Table 1. As the first step towardsimplementing the strategy, 14 authorities ...

  • Air quality assessment in Bologna by an urban dispersion model

    An urban dispersion model (ADMS?Urban) was run to calculate PM10 and NO2 concentration during a one-year period, on a district of Bologna, Italy. Moreover, the exposure of 333 children was estimated using model outputs corrected with observations. The model was able to correctly simulate the long-term statistical properties of roadside observed concentrations (such as annual mean and frequency ...

  • Urban domestic wastewater: how to reduce individual injection?

    The present paper aims to identify ways to reduce pollution injected by residents in the urban wastewater network system. Two approaches are considered. The first one uses flow and pollutant calculation to test whether a polluter can easily be identified in a neighborhood. The second approach uses a survey to examine what incentive would be most effective to influence residents’ behavior. ...

  • Modelling of air pollution from road traffic

    This paper presents the basic principles of the method of calculating air pollution from road traffic in an urban built-up area. The algorithm of the method is based on the numerical integration of stationary two-dimensional partial differential equations of turbulent diffusion, with boundary conditions for the street canyons. The method consists of two modules: KALIB and STREETS, which calculate ...

  • Dynamic modelling of transient emissions and concentrations from traffic in street canyons

    In the EU 5th framework project DECADE (2001–2003), a new methodology has been developed to calculate in detail the engine power required to drive a given vehicle over any particular route. It includes the rapidly changing (transient) demands placed on the engine, an area that has proved an obstacle to accurate simulations in the past. Together with the associated speed profiles, the actual power ...

  • The Economic Toll of Pollution’s Effects on Health

    Measuring and valuing the health impacts of pollution are very complex and available methods of economic analysis are often rudimentary. In recent years, considerable progress has been made, especially in respect to air pollution. This note summarizes the latest findings and outlines some basic approaches that can be applied in the economic analysis of Bank projects and sector studies. However, a ...


  • Some aspects of air pollution in Buenos Aires city

    This paper presents three aspects of air pollution in the city of Buenos Aires (Argentina). First, we describe the main features of air pollution climatology in the city: the characteristics of wind flow, atmospheric stability and mixing heights. Then, we present the results of the application of DAUMOD and ISCST3 atmospheric dispersion models to calculate spatial and temporal distributions of ...

  • The development of a novel approach for assessment of the first flush in urban stormwater discharges

    The management of stormwater pollution has placed particular emphasis on the first flush phenomenon. However, definition and current methods of analyses of the phenomena contain serious limitations, the most important being their inability to capture a possible impact of the event size (total event volume) on the first flush. This paper presents the development of a novel approach in defining and ...
