A series of Fe–Mn binary oxides with different Fe:Mn ratios (1:1, 3:1, 6:1, 9:1) were synthesized to investigate the optimal Fe:Mn ratio for the removal of As(III) and As(V). Batch experiments were performed to determine the rate of adsorption and equilibrium isotherms. Adsorption kinetics were well described by the pseudo-second-order kinetic model for both As(III) and As(V). The adsorption ...
Stream ecosystems may suffer from the effects of multiple stressors. Planning restoration actions without knowing the relative weight of each stressor might lead to disproportionately costly or ecologically meaningless measures. This is particularly relevant under the EU Water Framework Directive where economic considerations play a role in justifying exemptions from the overarching aim of the ...
The authors examined the seasonal and year‐to‐year variations of mercury (Hg) concentrations in populations of perch (Perca fluviatilis) from 2 boreal freshwater lakes in southeast Norway. Fish Hg concentrations were determined seasonally (spring, summer, and autumn) over 3 yr (2010, 2011, and 2012) to test the hypothesis that there are substantial changes in fish Hg concentrations during the ...
In this paper, an attempt is made to analyse the literature on business continuity, provide a systemic framework for business continuity in today’s e-business era, and identify further research directions. The paper primarily focuses on the ICT-dimension with regard to the role of information technologies in enhancing business continuity. A conceptual model based on systemic approach has been ...
New and higher standards in the EU water framework directive necessitate advanced treatment of secondary effluents for reduction of trace organic compounds (TrOCs) and nutrients before the discharge into receiving surface waters. Due to its dual function as oxidant and coagulant, ferrate is considered as a promising alternative for tertiary treatment. The oxidation of selected TrOCs and ...
Accurate knowledge of groundwater levels and flow conditions in the vicinity of groundwater-dependent terrestrial ecosystems (GWDTE-s) is required for identifying groundwater dependency and comparing the present situation with the optimal one, as part of the status assessment of groundwaters according to the EU Water Framework Directive. Geostatistical methods (like kriging or cokriging) may ...
EEA Catchments and Rivers Network System – ECRINS v1.1 The European Catchments and Rivers Network System (ECRINS) is the hydrographical system currently in use at the European Environment Agency (EEA) as well as widely serving as the reference system for the Water Information System for Europe (WISE). The first version of ECRINS (version 0 or â) was released in December 2008, and was ...
The European Water Framework Directive (WFD) prescribes that all water bodies in Europe should achieve ‘good ecological status’ (GES). Maintaining a certain water flow is a pre-condition for the achievement of GES in areas of water scarcity. In such areas, reclaimed waste water is seen as a promising measure to keep river flow at a sufficient level. The contingent valuation method is applied here ...
The Water Framework Directive has introduced a new governance approach that offers implementing agencies in EU Member States policy discretion to implement ecological ambitions. The aim of this paper was to gain insight into the way regional actors use this discretion and into the rationale behind their behaviour. Our research revealed that in regional implementation processes in the Netherlands, ...
Green drivers, such as reduced packaging (with consequently increased development of concentrated products) and climate change (with potentially decreased availability of water, reduced dilution of sewage plant effluents, etc.) pose a business risk to consumer products companies who manufacturer cleaning products that are likely to be disposed of to domestic sewers. Water Company responses to the ...
In 2005, the Department of Environment, Food, and Rural Affairs (Defra) proposed that the UKTAG Chemistry Task Team (CTT) should develop standards for certain Dangerous Substances Directive (DSD) List II substances as Annex VIII substances under the Water Framework Directive. These are substances for which EQSs are currently available, i.e. List II parameters as listed in the Dangerous Substances ...
This paper explores cross-scale governance between the European Union (EU) and Member State level arising from the identification of key policy priorities by stakeholders in six river basins across Europe and their relationship to EU policy development and implementation. Particular emphasis is given to interpretation of Good Ecological Status in implementing the EU Water Framework Directive, ...
Public participation in the form of informing, consulting and actively involving all interested parties is required during the implementation of the Water Framework Directive (WFD). This paper discusses progress with implementation of the WFD in Denmark and the measures taken to conform to the requirements for public participation. The first aim of the paper is to establish whether enough is ...
Water Framework Directive (WFD) statutory authorities and stakeholders in Ireland are now challenged with the issue of how the proposed programmes of measures in the newly required River Basin Management Plans – designed to protect and restore good ecology by reverting as closely as possible back to natural conditions – are to be implemented in a way that concurrently complies with other existing ...
Since 2005, several cost benefit analyses have been performed for the European Water Framework Directive (WFD) in The Netherlands. These analyses had in common that they were meant to support the decision-making process by informing policy makers and making the trade-offs as transparent as possible. The analyses also anticipate questions from the Dutch Parliament. Nevertheless, each time the ...
According to the European Water Framework Directive (WFD), cost-effectiveness analysis (CEA) should be used for measuring the cost and the environmental effectiveness of a measure in water quality management. The purpose of this paper is to argue that, beyond the calculation of the cost efficiency of the measures, additional information related to the cost and the environmental characteristics is ...
An uprising questioning within the general frame of environmental protection focuses on the impact of everyday use products. When we make use of any product, our thought focuses solely on the use. Still, a deeper retrospect reveals numerous hidden aspects: Each product consists of several parts, for the production of which a significant amount of energy has been consumed; the use of the product ...
As a new member of the European Union, Hungary is obliged to adopt the Water Framewok Directive and develop river basin management plans at various levels. To prepare the planning process, a pilot project was conducted, with a focus on the Upper Tisza region, in which the involvement of a multidisciplinary expert group was combined with the participation of local stakeholders. Tools of public ...
Danger over for swimmers: what appears to be disgusting, is purely natural – algae Lake Twiste is clean and free of blue-green algae even if at the moment there is a large amount of filamentous algae present. However, this is not a problem and completely natural, Andreas Gründel, Environmental Engineer from the Hessen State Authority for the Environment and Geology explained. A ...
