  • Modeling Tip: How to Import BREEZE AERMOD files into BREEZE Risk Analyst for Human Health Risk Assessments

    Humans can be exposed to hazardous air pollutants (HAPs) either directly through inhalation or indirectly through ingestion or dermal contact, which can result in acute or chronic health effects. The risk of exposure varies depending on a number of variables, including the meteorological conditions, local geographical and emissions characteristics, the age of the individuals being exposed, and ...

  • Fireworks air pollution in Slovenia

    Over the 'Christmas–New Year' period 12/2010–01/2011, PM10 air pollution measurements on most of the automatic measuring stations in Slovenia reached extreme values of up to 300 µg/m³. Analysis shows a very close correlation with the timings of the fireworks displays in the areas. This paper shows the other side of this cultural enjoyment - the effect on PM10 air pollution. As the correlation ...

  • 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 ...

  • Modelling of air pollution in the area of Algiers City, Algeria

    Algiers is the political and economic capital of Algeria. The city drains a large part of the activities of the country with intense road traffic. This road traffic is the main source of air pollution, followed by industry and waste combustion. An application of the new road traffic emission model, called EMISENS, is performed to build road traffic emission inventories for the Algiers region. ...

  • Operational short-range analytical air pollution modelling

    Operational models that use solutions of the advection-diffusion equation based on more realistic assumptions than that of homogeneous wind and eddy diffusivity coefficients are presented. In particular, these solutions accept that wind and eddy diffusivity profiles are power functions of the height. Moreover, a practical short-range model evaluating ground-level concentrations from elevated ...

  • Different splitting techniques with application to air pollution models

    Splitting techniques are commonly used when large-scale models, which appear in different fields of science and engineering, are treated numerically. Four types of splitting procedures are defined and discussed. The problem of the choice of a splitting procedure is investigated. Several numerical tests, by which the influence of the splitting errors on the accuracy of the results is studied, are ...

  • State of the art of air pollution models, needs and trends

    This paper summarises the results of the investigations within task MA3-2 carried out by the European Topic Centre on Air Quality. The main aim of this task is to describe the state of the art of air pollution models, with special emphasis on needs for model application and trends in model development. From the results it can be inferred to what extent the needs are met by available models and ...

  • Air pollution modelling, sensitivity analysis and parallel implementation

    A new approach for Sensitivity Analysis (SA) in the field of air pollution modelling is proposed and applied to the Unified Danish Eulerian Model (UNI-DEM), a large-scale air pollution model. The SA requires numerous model experiments with different values of the studied parameters. By simultaneous variation of these parameters we produce a set of multidimensional discrete functions. These huge ...

  • Dispersion models and air quality data for population exposure assessment to air pollution

    Evaluating the extent of exposure to chemicals in absence of continuous measurements of their concentration in air and direct measures of personal exposure is crucial for epidemiological studies. Dispersion models can be a useful tool for reproducing spatio-temporal distribution of contaminants emitted by a specific source. However, they cannot easily be applied to short-term epidemiological ...

  • AirQuis: A basis for air pollution forecasting

    The GIS based air quality planning system, AirQUIS, represent a perfect platform for developing numerical air quality forecasting.  AirQUIS The Air Pollution Surveillance and Information System, AirQUIS, has been developed on a Geographical Information System (GIS) platform. The main objective has been to enable direct data and information transfer and obtain a remote quality control of ...

  • Evaluation of air pollution trends in Istanbul

    Previously, SO2 and PM10 (particulate matter less than 10 Bm in size) concentration distributions have been investigated in order to assess air pollution in Istanbul during the winter season (November–March) in which the concentration of these pollutants had reached formidably high levels due to the consumption of low-quality fuels (mainly coal) for residential ...

  • Coupling of neural network and dispersion models: a novel methodology for air pollution models

    Supervised neural net models and dispersion models are two important approaches for evaluating air pollution concentrations. The authors propose the development of an integrated model, in order to optimise the performances of each methodology. The concentrations evaluated by an air pollution model are coupled with a Neural Net (NN), so as to adjust the influence of important variables on ...

  • 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 ...

  • Air pollution – the invisible roadside killer

    The VW emissions scandal has helped to raise awareness of the deadly threat posed by air pollution in many of our towns and cities. In the following article, Jim Mills, Managing Director of Air Monitors, an instrumentation company, explains why diesel emissions will have to be lowered and how the latest monitoring technology will be an essential part of the solution. ...
