利用综合指标和一元分布拟合筛选重点污染源

首次将综合指标和数理统计一元分布拟合方法运用于重点污染源的筛选,通过筛选排污量离群单位来确定重点污染源.研究了污染物排放量的分布,污染源各污染物排放量之间的关系;在进行重点污染源的筛选时,针对污染源所处不同地理位置或不同排放去向,可造成不同危害程度的问题,采取了对污染源所处地理位置或排放去向进行加权的方法;针对当污染源排放多种污染物,多参数筛选难于综合考虑的问题,提出了采用综合参数进行筛选的方法.采用的重点污染源的筛选方法更具有理论依据和科学性.     

State of the Art Report on Mathematical Methods for Groundwater Pollution Source Identification

The reliable assessment of hazards or risks arising from groundwater contamination problems and the design of efficient and effective techniques to mitigate these problems require the capability to predict the behavior of chemical contaminants in flowing water. Most attempts at quantifying contaminant transport have relied on a solution of some form of a well-known governing equation referred to as advection-dispersion-reaction equation. To choose an appropriate remediation strategy, knowledge of the contaminant release source and time release history becomes pertinent. As additional contaminated sites are being detected, it is almost impossible to perform exhaustive drilling, testing, and chemical fingerprint analysis every time. Moreover, chemical fingerprinting and site records are not sufficient to allow a unique solution for the timing of source releases. The purpose of this paper is to present and review mathematical methods that have been developed during the past 15 years to identify the contaminant source location and recover the time release history.     

The Importance of Contexts in Strategies of Environmental Organizations with Regard to Climate Change

2 problem, which brought the issue into the energy debate, as well as the more general definition of the problem in the late 1980s as a greenhouse problem, were very important for determining the strategies of the organizations. It can be concluded that strategies of Dutch environmental organizations with regard to climate change were strongly dependent on the context.     

Specifying information needs: improving the working methodology

Specification of information needs is an important step in the design of monitoring networks. Within the framework of Monitoring Strategy 2000+, a programme of the Dutch Directorate General of Public Works and Water Management (Rijkswaterstaat) which seeks to provide innovation in the monitoring sector, a method has been developed to link water management policy to monitoring through specification of information needs. Over the past 2 years, this method has been applied in several projects within the Rijkswaterstaat organisation. Use of this method has led to improvements in the monitoring practice and was judged very positively by the people involved. Nevertheless, the main obstacle to employing the method was the actual translation of policy matters into information products. A special study is carried out, focusing on this aspect within the method, to provide the participants of a project with a mental framework that enables them to clearly specify their information needs. The major requirements for this mental framework are that all participants have a clear view of the process (system), and that they are able to relate their contribution to this process and to the contributions of others (transparency). The first step of the process is to focus the attention of stakeholders on the information they will actually need for decision-making. The next step is to confront the different expressed opinions through the method of the 'devil's advocate', which implies criticising the results of the first step by finding as many as possible arguments against these opinions. This should force the stakeholders to better specify their arguments. The method, its improvements and the results of one pilot project will be discussed in this paper. Electronic Publication
