  • Environmental modelling for blue collars

    Model complexity and the ‘breakpoint of diminishing returns’; ‘physical’ vs. ‘conceptual’ modelling; the relevance and limits of the heuristic solutions; screening vs. analytical modelling; perceptions of uncertainties, calibration and sensitivity analysis; and the ‘ethics in modelling’ – are only a few issues outstanding in the volatile philosophy of the environmental modelling. Glossing on ...

  • Modelling trade and environmental linkages in China

    Interactions between trade and the environment have been studied extensively as a reaction to the pressure that the accelerated pace of globalisation has placed on environment and trade. Distinguishing itself from previous work, this study focuses on a modelling analysis of the interactions between trade and the environment in China. A non-linear simultaneous equation trade and environment model ...

  • Comparison of linear and non-linear models for the adsorption of fluoride onto geo-material: limonite

    The three widely used isotherms Langmuir, Freundlich and Temkin were examined in an experiment using fluoride (F−) ion adsorption on a geo-material (limonite) at four different temperatures by linear and non-linear models. Comparison of linear and non-linear regression models were given in selecting the optimum isotherm for the experimental results. The coefficient of determination, r2, ...

  • A geo-referenced modeling environment for ecosystem risk Assessment: Organophosphate pesticides in an agriculturally dominated watershed

    Received for publication May 5, 2008. A geo-referenced modeling system was developed in this study to investigate the spatiotemporal variability of pesticide distributions and associated ecosystem risks. In the modeling system, pesticide fate and transport processes in soil-canopy system were simulated at field scale by the pesticide root zone model (PRZM). Edge-of-field mass fluxes were ...

  • Relating geo–meteorological parameters to global solar radiation for Egypt by Iranna–Bapat's estimation models

    Estimation of solar radiation is considered as the most important parameter for the design and development of various solar energy systems. But, the availability of the required data is very scarce and often not readily accessible. The foremost objective of the present study was to estimate the monthly average global solar radiation (GSR) at various locations for Egypt, by the generalised ...

  • Understanding QSPR uncertainty in environmental fate modeling

    In cases where experimental data on chemical‐specific input parameters are lacking, chemical regulations allow the use of alternatives to testing, such as in silico predictions based on quantitative structure‐property relationships (QSPRs). Such predictions are often given as point estimates; however, little is known about to what extent uncertainties associated with QSPR predictions contribute ...

  • Endogenous technology and environmental quality in economic models

    The debate on the relationship between the economy and the environment focuses on the question whether there is a trade-off between economic growth and environmental quality. In order to enable a quantification of this essentially empirical question, it is necessary to integrate the environment into economic models. This article considers the integration of the environment in models of economic ...

  • On the formulation of environmental fugacity models and their numerical solutions

    Multimedia models based on chemical fugacity, solved numerically, play an important role in investigating and quantifying the environmental fate of chemicals such as persistent organic pollutants (POPs). These models have been utilised extensively in the study of the local and global distribution of chemicals in the environment. This paper describes potential sources of error that may arise ...

  • Regulatory models for environmental impact assessments in Hungary

    This paper describes the methodology and input requirements of environmental impact assessments regulated in Hungary by national standards for more than 10 years. The main characteristics are (a) various models simulate the impact of point, multi-source, line and area sources on local, urban and regional scales, (b) design transmission matrices are readily available for the greater part of the ...

  • Atmospheric environmental impact assessment modelling in France

    The most widely accepted model of atmospheric dispersion for impact assessment in France is the Gaussian model of Doury. The Centre d'Etudes Atomiques (CEA) and Electricite de France (EDF) have developed their own software systems, which include several compatible or nested meteorological, trajectory, and dispersion codes. These systems are fitted to the various atmospheric scales from regional ...

  • Environmental Noise

    Introduction The ability to hear sounds is a sensory function vital for human survival and communication. However, not all sounds are wanted. 'Unwanted sounds', for which the term 'noise' is normally used, often have their origin in human activities (mainly transport, industry and households). This article addresses environmental noise ­ also referred to in the scientific literature as ...

  • Models of energy saving systems: the battlefield of environmental planning

    Traditionally, energy planning has been interpreted as planning for an appropriate energy supply system, based on a crude prognosis for the energy demand. Over the past couple of decades, however, the immense possibilities of regulating energy demand - and the benefits of doing it - have become increasingly recognised and also partly included in the planning. This paper first describes some ...

  • Improved environmental multimedia modeling and its sensitivity analysis

    Modeling of multimedia environmental issues is extremely complex due to the intricacy of the systems with the consideration of many factors. In this study, an improved environmental multimedia modeling is developed and a number of testing problems related to it are examined and compared with each other with standard numerical and analytical methodologies. The results indicate the flux output of ...

  • The Third Workshop's environmental impact assessment model intercomparison exercise

    Twelve European modelling teams calculated the impact of a 600 MW power plant, using one of their national regulatory transport and dispersion models. They were asked to report the model results in a uniform way and to provide detailed information on the meteorological data and on the model used. Three modelling teams, from Greece, Germany and Belgium, used the same meteorological dataset. The ...

  • Application of dispersion models in the environmental assessment process in the United Kingdom

    The UK planning process has traditionally been separated from the licensing process as far as industry is concerned. Implementation of the Environmental Assessment Directive (85/337/EEC) has therefore been the responsibility of planners, not pollution regulators. This is one of the reasons why there are no formalised procedures for using dispersion models in the environmental assessment ...

  • Neural network model for identification of societal preference of environmental issues

    A new method for identification of preferences of environmental issues using the societal approach is suggested. The preferences assigned by different economic groups to 11 environmental issues are obtained through analysis of linguistically stated relative rankings using fuzzy partial ordering method. The system identification technique based on neural networks is used to identify a logical ...

  • Applying an ethical decision–making model: the case of Avco Environmental

    This paper discusses the principles of ethical decision–making at enterprises, as a tool for corporate social responsibility. In particular, it focuses on the particularities inherent to ethical guidelines in an organisation. A case study from an environment company provides the basis for an analysis, in the context of which the role played by ethical issues, as well as some steps to ensure they ...
