Eine systematische Übersicht über Fragebögen aus Lärmwirkungsstudien

In Fragebogen-Untersuchungen zur Lärmwirkung wurden bisher sehr unterschiedliche Operationalisierungen von Wirkungsvariablen (wie z.B. Belästigung, Störung von Aktivitäten) und außer-akustischen Faktoren (sog. Moderatoren wie z.B. Lärmempfindlichkeit, misfeasance) verwendet. Deshalb hat sich die Arbeitsgruppe community response der International Commission on the Biological Effects of Noise (ICBEN, Team No. 6) als langfristiges Ziel die Entwicklung von Fragebogen-Guidelines und die Formulierung eines Muster-Fragebogens für die Lärmwirkungsforschung gesetzt. D.h. es soll ein Vorschlag erarbeitet werden, in welcher Form globale und spezifische Lärmwirkungen in Befragungen erhoben werden sollten. Um dieses Vorhaben zu unterstützen, hat der Arbeitskreis Ökologische Lärmforschung die Erstellung einer systematischen Übersicht über vorhandene Fragebögen aus Lärmwirkungsstudien auf internationaler Ebene in Angriff genommen. Diese Übersicht soll es u.a. ermöglichen, die Struktur von verschiedenen Fragebögen sowie die in ihnen verwendeten Operationalisierungen für Lärmwirkungs- und Moderatorvariablen (hinsichtlich Art der Frageformulierung sowie der Antwortformate) zu vergleichen. Für den/die einzelne/n Lärmforscher/in bietet diese Übersicht die Möglichkeit, sich auf sehr effiziente Art und Weise darüber zu informieren, wie bestimmte Konstrukte in bisherigen Untersuchungen operationalisiert worden sind bzw. welche Alternativen zu den bereits selbst angewandten Operationalisierungen bestehen. Nach einer systematischen Ermittlung von Namen und Adressen einschlägiger Lärmforscher/innen, wurden diese um die Zusendung von Fragebögen sowie ergänzender Materialien aus eigenen Lärmwirkungsstudien gebeten. Die zugesandten Fragebögen werden gegebenenfalls übersetzt und mit der Methode der qualitativen Inhaltsanalyse ausgewertet. Hierbei werden die Fragebögen im Hinblick auf formelle Aspekte (z.B. Jahr der Erhebung, Sprache, Art der Befragungsmethode) wie auch im Hinblick auf strukturelle Aspekte (z.B. Umfang des Fragebogens, abgefragte Variablengruppen, Antwortformate) ausgewertet. Hauptgegenstand der Auswertung ist aber insbesondere die Auswertung der Lärmwirkungsvariablen (z.B. die Abfrage der globalen Lärmbelästigung, Aktivitätenstörungen, Kommunikationsstörungen) sowie der Moderatorvariablen (z.B. Lärmempfindlichkeit, Lärmbewältigungsvermögen, misfeasance). Parallel dazu wurde eine Datenbank entwickelt, in der die Ergebnisse der Analysen dargestellt und verwaltet werden. Diese Datenbank wird ab November 2001 im Internet unter http://www.eco.psy.ruhr-uni-bochum.de/nqd für jede/n interessierte/n Forscher/in zugänglich und nutzbar sein. Langfristig ist darüber hinaus geplant, ein Archiv mit den Original-Fragebögen aufzubauen, in dem einzelne Fragebögen auf Wunsch eingesehen werden können.

ERA-NET - Development of test methods for non wood small-scale combustion plants

Non wood fuels for small-scale furnaces have attracted increasing interest in several European countries. New technological approaches are on the way, but the verification of any such developments is difficult and there is a large uncertainty about testing procedures and equipment. While for wood combustion standardized European measuring regulations are available and broadly applied, the testing of cereal fuel combustion is generally not following a commonly accepted procedure. Consequently the results of such measurements are not fully comparable. This applies particularly for the international level, which is here of particular relevance due to the fact that a combustion technology development for a niche application can only be economically viable if a sufficiently large marketing area can be taken into focus. The overall objective of the proposal is therefore to contribute through research to the development of uniform and comparable European procedures for testing of small-scale boilers up to a power out of 300 kW for solid biomass from agriculture like straw pellets and energy grain. The driving forces and barriers will be worked out; existing legal regulation for the installation (approval by the local authorities) in the participating countries will be collected. The state of the art of the non wood biomass boiler technology will be identified; the need for standardized tests for type approval tests and the measures to establish a European Standard will be shown. Measurement methods with special emphasis on efficiency and emissions will be worked out and the requirements and specifications of test fuels will be proposed. Test runs will be carried out following preliminary test procedures based on existing European standards for wood boilers. Based on the results of these test runs a draft for a Europe-wide uniform test procedure will be proposed. Preparatory work for a European standardization process including a round robin test will be done.

Entwicklung naturschutzfachlicher Grundlagen zur Honorierung ökologischer Leistungen der Forstwirtschaft

Problemstellung: Der Begriff der 'Guten fachlichen Praxis (GfP) in der Land- und Forstwirtschaft definiert rechtlich verankerte ökologische und naturschutzfachliche Mindestanforderungen an die Bewirtschaftung. In der Novelle des Bundesnaturschutzgesetzes wurde die GfP für die Landwirtschaft über Grundsätze mit konkreten Anforderungen verbunden. Die Chance der Integration naturschutzfachlicher Zielsetzungen in die Landbewirtschaftung soll auch für eine multifunktionale Forstwirtschaft genutzt werden. Dabei gewinnt die Ausgestaltung von weiterführenden finanziellen Anreiz- und Ausgleichssystemen zunehmend an Bedeutung. Sowohl die Vertreter des Waldbesitzes wie auch des Naturschutzes verweisen darauf, dass die Ziele des Waldnaturschutzes mit regulativen Instrumenten allein nur unzureichend sichergestellt werden können (siehe Nationales Waldprogramm, Erster Deutscher Waldgipfel). Deshalb sollten neben der legalen Definition der GfP naturschutzfachliche Grundlagen für den Einsatz finanzieller Instrumente zur ökologischen Honorierung naturschutzrelevanter Leistungen als ergänzender Baustein einer naturschutzpolitischen Gesamtstrategie für den Wald entwickelt werden.

FP6-POLICIES, Background Criteria for the Identification of Groundwater Thresholds (BRIDGE)

The Commission proposal of Groundwater Directive COM(2003)550 developed under Article 17 of the Water Framework Directive (2000/60/EC) sets out criteria for the assessment of the chemical status of groundwater, which is based on existing Community quality standards (nitrates, pesticides and biocides) and on the requirement for Member States to identify pollutants and threshold values that are representative of groundwater bodies found as being at risk, in accordance with the analysis of pressures and impacts carried out under the WFD. In the light of the above, the objectives of BRIDGE are: i) to study and gather scientific outputs which could be used to set out criteria for the assessment of the chemical status of groundwater, ii) to derive a plausible general approach, how to structure relevant criteria appropriately with the aim to set representative groundwater threshold values scientifically sound and defined at national river basin district or groundwater body level, iii) to check the applicability and validity by means of case studies at European scale, iv) to undertake additional research studies to complete the available data, v) and to carry out an environmental impact assessment taking into account the economic and social impacts. The project shall be carried out at European level, involving a range of stakeholders and efficiently linking the scientific and policy-making communities. Considering the requirement of the diary of the Groundwater Daughter Directive proposal, which implies that groundwater pollutants and related threshold values should be identified before December 2005 and listed by June 2006, the duration of the project should be 24 months. In that way the proposed research will contribute to provide research elements that will be indispensable for preparing discussions on further steps of the future Groundwater Directive.

FP6-SUSTDEV, Reduction, modification and valorisation of sludge (REMOVALS)

The adoption of the Urban Waste Water Treatment Directive 91/271/EEC imposes the sewage sludge to be subsequently treated so it is expected by 2005 to increase twofold in comparison whit 1992. However, classical incineration to treat this vast amount of sludge must be no longer accepted from an environmental point of view. In addition, the Sewage Sludge Directive 86/278/EEC regulates the uses and properties of stabilised sludge for being either recycled or disposed. Both directives drive specific actions in two complementary ways. Firstly, a deep knowledge of current sludge treatment, such as mesophilic, thermophilic or autothermophilic processes, must be promoted to solve that problem in the UE ambit, taking in account the particular considerations of each treatment facility. In second place, the development of new processes must be supported to open new alternatives that could valorise that waste.The proposal aims at developing strategies for the disposal and reuse of waste sludge. The scope envisages to develop several processes for reducing both amount and toxicity of sludge, with simultaneous transformation into green energy vectors such as methane or hydrogen. In outline, mesophilic and mainly thermophilic and autothermophilic conditions will be deeply explored as classical alternatives for sludge stabilisation, assuring sanitary conditions of the treated sludge. Also, valuable materials will be obtained from sludge, such as activated carbons, which will be used in conventional adsorption processes and in innovative advanced oxidation processes.The main outcomes expected at the end of the projects are guidelines for technology selection in agreement with the geographic, economic and technical characteristics of the sewage plants, demonstration of the feasibility of new applications for the sewage sludge, manufacturing of activated carbon from sludge sewage as innovative recycling of sludge waste, and a deep understanding of the methods involved.

Towards the Derivation of Quality Standards for Priority Substances in the Context of the Water Framework Directive - Identification of Quality Standards for Priority Substances in the Field of Water Policy

Article 16 of the Water Framework Directive (WFD, Directive 2000/60/EC) lays down the Community Strategy for the establishment of harmonised quality standards and emission controls for the priority substances and other substances posing a significant risk to, or via, the aquatic environment. In order to achieve the protection objectives of the WFD, the Commission shall (i) submit proposals for quality standards applicable to the concentrations of the priority substances in surface water, sediment or biota, and (ii) identify the appropriate cost-effective and proportionate level and combination of product and process controls for both point and diffuse sources. Proposals for environmental quality standards and emission controls for point sources shall be submitted within 2 years of the inclusion of the substance concerned on the list of priority substances (European Parliament and Council Decision No. 2455/2001/EC), i.e. in December 2003. This study is part of the preparatory work of the Commission and its overall objectives are: - The development and description of a concept which enables the European Commission to submit proposals for quality standards applicable to the concentrations of the priority substances of the Water Framework Directive (2000/60/EC) and those substances not on the priority list but regulated in the 'daughter directives' of Directive 76/464/EEC (on pollution caused by certain dangerous substances discharged into the aquatic environment of the Community) in water, sediment and biota, as required by Articles 16(7) and 16(10) of the Water Framework Directive. - Elaboration of proposals for quality standards for the priority substances of the Water Framework Directive and recommended values for other substances of concern (see footnote 1) with regard to surface water, sediment, biota, and human health as objectives of protection. Conclusions: The elaboration of quality standards with the developed methodological framework clearly showed that the proposed approach is applicable for the derivation of specific quality standards addressing the particular objectives of protection as well as for the identification of the overall quality standard that finally may be imposed to safeguard the entire set of objectives of protection. Also, with regard to the effort required to work with the concept, it can be considered as economic. This is attributable to the fact that despite the comprehensive consideration of all relevant routes of exposure and objectives of protection the different quality standards for the specific objectives are normally only derived if certain pre-defined trigger values are exceeded. This avoids the assessment of irrelevant exposure routes and the calculation of unnecessary standards. Problems encountered during the elaboration of the standards were in general not attributable to the suggested methodological framework but mostly to the limited availability of data or to the limitations of the available data.

Ziel des Schwerpunktprogramms 1144 (SPP 1144) ist die interdisziplinäre und zeitlich-räumliche Erforschung des mittelozeanischen Spreizungssystems im Atlantik. Für diese Untersuchungen wurden zwei Gebiete (bei 15 Grad N und 4-11 Grad S) ausgewählt. Das Programm hat insbesondere zwei hoch-innovative Ansätze. Die Zusammenhänge zwischen den Prozessen in diesen Gebieten durch den Einsatz verschiedenster Forschungsrichtungen, wie der Petrologie, Vulkanologie, Geodynamik, Geophysik, Hydrothermalismus, Mikrobiologie, Makrobiologie, Ozeanographie, Wasserchemie und Konvektionsmodellierung zu erfassen. Die Nutzung hochentwickelter ferngesteuerter Unterwasserfahrzeuge (ROV, AUV u.a.) für eine genaue Beobachtung und Beprobung des Meeresbodens. Nach den ersten vier erfolgreichen Jahren, beantrage ich hier die Infrastruktur, die nötig ist, um das Schwerpunktprogramm, inklusive aller Einzelanträge, so effektiv wie möglich und mit dem größtmöglichen wissenschaftlichen Output' zu Ende führen zu können. Hierzu werden drei grundsätzliche Bereiche benötigt: (1) ein Koordinationsbüro, um zwischen den verschiedenen Arbeitsgruppen zu vermitteln und alle über die Abläufe innerhalb des SPP zu informieren, zur Koordination der Schiffseinsätze und der Workshops und zur Einbindung des SPP in die große InterRidge Gemeinschaft und Aktivitäten; (2) technisches Personal, das notwendig ist, um die Tiefsee-Technologien jederzeit für Einsätze zur Untersuchungen der Spreizungachsen zur Verfügung stellen zukönnen, (3) Datenmanagment, um alle Beteiligten des SPP mit allen verfügbaren Informationen zu versorgen und um alle Ergebnisse des SPP in eine umfassende Datenbank zusammenzuführen.

FP6-SUSTDEV, Co-ordination Action to define new research lines on Life- Cycle Analysis for sustainability (CALCAS)

LCA approaches are part of the broader field of sustainability assessment often connected to different disciplines. To increase the efficacy of sustainability decision making, LCA is to take into account broader externalities, broader interrelations and different application/user needs with often conflicting requirements (dynamic models; integration of environmental, economic, and social aspects; accessibility and user friendliness, etc). Roughly, development should be oriented to: - 'deepening', to improve reliability and usability by more adequately incorporating empirical mechanisms - 'broadening', to improve the significance, by expanding the scope of sustainability impacts and better linking to neighbouring models - 'leaping forward' by a revision/enrichment of foundations, through the crossing with other disciplines for sustainability evaluation. CALCAS develops analysis and development along two lines: 1 science framework; 2 user needs (Industry, Research organisations, Government, Consumers, NGOs); the results, are crossed to draw up mid- long-term research lines and road maps, including measures for implementation. Advanced results will often not be in line with the current ISO14040 series definitions and requirements on LCA, creating a need for reformulation. Partnership combines LCA 'producers' and 'users' and involves, with different responsibilities, a significant and highly qualified part of European scientists. Thus, the project promotes the networking both 'cross', among the scientific sectors, and 'vertical' between them and users. Expert working groups, cross-fertilisation workshops, and an open consultation of all scientific sectors and users, based on a Blue Paper combining intermediate proposals are inputs to the final results, both as described models and tools and as research tasks to be accomplished. They also promote dissemination and joint actions for training, knowledge exchanges and common projects. Prime Contractor: Ente per le Nuove Tecnologie, l'Energia elL'Ambiente; Roma; Italy.
