In dynamic river systems, effective and sustainable risk management of sediments, contaminants and their sources must be carried out on a river basin scale. A diversity of interests and risk perceptions, whether environmental, economical, or personal, as well as the broad variety of uses and functions of river systems can lead to conflicts and disagreements about how and where river systems should be managed. This requires a transparent methodology to assess environmental risks in the river basin, followed by a prioritisation of those sites where measures would yield the highest positive effect for the river basin and where financial resources could be allocated most efficiently. However, risk perceptions may only partially be influenced by scientific assessments of risk, and often also depend on a variety of factors such as personal experience and confidence in institutions. Risk managers must develop methods to balance technical and socioeconomic issues with the aim to reduce risks posed by sediments to environmental and economic resources to a level that is perceived as tolerable by society. Sediment Risk Management and Communication (Vol.3 in the SEDNET mini-series) is based on discussions that were held in the working group on "Risk Management and Communication" which was one of 4 working groups within the European Demand-Driven Sediment Research Network "SedNet". It aims to analyse the current situation in Europe with regard to sediment risk management issues, to draw conclusions from this analysis and to offer recommendations for sustainable risk management from basin to site-specific scale. * A broad overview on sediment quality and impact assessment of pollutants * Suitable for both newcomers to the field of sediment treatment and specialists alike * Outlines practical examples of methods used in sediment quality analysis

These proceedings describe the current state-of-the-art of ozone research. A wide range of topics is discussed including: emissions, transport and transformation of precursors of ozone and of ozone itself, the distribution of ozone, the deposition of ozone at the earth's surface, and its effects on man and the environment. Attention is also given to the role of stratospheric ozone and the role of the ultraviolet radiation which is transmitted through the ozone layer. Finally it describes in detail present and future policy measures to reduce the ozone in the lower atmosphere and to protect the ozone layer in the stratosphere. Many of the papers describe recent developments and new research results. Research carried out in both in Europe and in the United States is described, as are the policy measures which are being taken by both European and U.S. governments

Climate change is an issue that is highly debated around the globe. This book brings together the papers that were presented at a conference dedicated to this issue, held in Kyoto in October 2002. Covering a broad range of areas, the topics presented will benefit both those working in the field of carbon dioxide recovery and sequestration, and those looking at the effects of non carbon dioxide greenhouse gases. An overview of the Research and Design technologies which aid in mitigating climate change is included, which will be invaluable to those researching new opportunities for dealing with this problem. An area of research that has seen a rapid rise in worldwide spend Will benefit both researchers in climate change, and those looking at new technologies to help deal with the problem Presents papers from contributors spread around the globe means that this book has world wide relevance
