  • 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... ...

  • European water policies and human health — Combining reported environmental information

    Society depends on the satisfactory and sustainable management of water. Historically, the primary purpose of water treatment was to protect human health, through reducing disease being transmitted through water. Subsequent measures to address environmental concerns have broadened our expectations of what water and waste water treatment should deliver. This report considers three pieces of EU ...

  • 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 ...

  • 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 ...

  • How To Handle Chemical Spills & Cleanups

    FAST-ACT is designed for liquid and vapor chemical releases, but the chemicals it attacks does not need to be limited to what we traditionally think of as a chemical spill. Toxic and noxious chemicals can come from a variety of sources such as waste water, decomposition, household chemicals, and animals. Since FAST-ACT can be applied to liquid spill or vapor release enabling Emergency Responders ...

  • 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 ...

  • Statistical analysis of urban air-pollution data in the Athens basin area, Greece

    Air pollutant concentrations recorded in the Athens basin area by a network of stations are analysed and examined to estimate the typical behaviour of the air pollutants, especially with regard to daily, weekly and annual periodicities and meteorological dependencies. Also, an attempt is made to predict daily and monthly concentrations by utilising a statistically based model, that is, a multiple ...

  • Biocatalysed acidification and metal leaching processes in sediments of polluted urban streams

    Sediments of fluvial streams are a sink for pollutants such as heavy metals and organic recalcitrant compounds. In anoxic conditions, sulphide generation and alkalinisation cause precipitation of heavy metals. The redox potential of the system could change to higher values, mainly owing to oxygen exposition generated by anthropogenic disturbances of the sediment such as dredging operations. ...

  • 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 ...

  • Application of an ISCST3 model for predicting urban air pollution in the Izmir metropolitan area

    A Gaussian atmospheric dispersion model, Industrial Source Complex Short Term (ISCST3), was used to estimate ground-level concentrations of sulphur dioxide (SO2) emitted from source categories of industrial and domestic heating in the city of Izmir, Turkey. Predictions were estimated for the year 2000 across a study area of 80 km x 100 km. Statistical analyses were carried out to evaluate ...

  • A Bayesian model for studying urban air pollution and respiratory symptoms in children

    The association between traffic–related air pollution and long–term respiratory health problems has been extensively studied. In this work we evaluated the effect of traffic–related air pollution on respiratory symptoms in children living in Florence, Italy. Children were selected from different schools part of the Italian Studies on Respiratory Disorders in Children and the Environment 2. ...

  • Evaluation of the meteorological data requirements of ADMS-Urban for modelling pollution in Northampton, England

    Atmospheric dispersion models are now being used by some local authorities in the United Kingdom as part of their management of urban air quality. Local authorities are also involved in using air pollution model outputs in environmental impact assessments for industrial projects, assessing the impact of road improvement or traffic management schemes and environmental health studies. This study is ...

  • 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 ...
