A large number of nationwide research programmes in the field of acidification have been carried out in the last decade. Especially in Western Europe, extensive programmes have resulted in a good overview of all the effects - mostly negative - caused by acidifying substances. There is now consensus that types of acidification damage relate to the unique geography of an area: air pollution affects vegetation; acid aerosol the ozone layer. New in this volume, is the relation between scientific results of integrated research programmes and policy actions to prevent, reduce and limit the widespread damage caused by acidification. The results of many different national research programmes are evaluated and compared to present a unique compilation for the research scientist and policy maker. In this volume thematic reviews on specific topics of acidification research are presented, followed by overviews of acidification policy plans and actual abatement plans. The result is the best review of acidification research carried out worldwide during the last decade and presentation of the critical relation between research results and policy actions.

The book begins with an overview of the research topics which were addressed in the three different phases of the Dutch Priority Program on Acidification (DPPA), executed between 1985 and 1994. This chapter is followed by a chapter which deals with the emissions of acidifying substances, the concentrations and the deposition to forest and nature conservation areas. Prognoses are given for the acid deposition in 2000 and 2010; the deposition in the countries surrounding the Netherlands is also mentioned. The differences in the results of the DPPA-II are analysed.The third chapter deals with the effects of exposure and load on forests. The chapter moves from small-scale to large-scale: first the effects in laboratory-scale studies are described, then the effects in the field, both at stand level and on a regional scale. In addition, the critical thresholds (critical level of concentration and critical load of deposition) are discussed.The fourth chapter covers terrestrial ecosystems (or parts thereof) as well as weakly buffered surface waters, springs and other streams. Critical levels and loads are also discussed. The most important results are given in chapter 5.In the appendices of the book, so-called umbrella theme reports on deposition, stand modelling and effects on forests are presented which describe in more detail the scientific work performed in the third phase of the DPPA.This book will be of interest to anyone involved in research related to acidification and eutrophication; i.e., not only those who perform the research in the causal chain from emissions to effects, but also policy-makers and students.
This title was first published in 2000: In examining the domestic politics of international co-operation, this book addresses two important questions: 1. Why do governments often take different positions in negotiations about common problems - why do some states push for international regulation while others hold back? 2. How can variance in the domestic implementation of and compliance with, international agreements be explained - why do some states deliver more than they have promised, others less? The authors report findings and observations from a major study which focused on efforts to establish international regulations to cope with the problem known as acid rain. They provide in-depth case studies of nine European countries as well as a comparative analysis searching for patterns and general conclusions.
This is a unique compilation on the use of leaching/extraction methods in different fields. The use of leaching test methods is increasing in various areas including: waste treatment and disposal; incineration of waste; soil clean-up and reuse of cleaned soil; sludge treatment. This has led to (and may increasingly lead to) the development of a large number of very similar tests in these different fields. However, these developments are taking place with no clear understanding of their mutual relationships. In view of these developments, efforts are needed to harmonize the leaching procedures that could be adapted for different matrices, as well as validate the use of existing tests in other fields. The development of a wide variety of leaching/extraction tests for different matrices is undesirable from a regulatory point of view and undesirable for industry. Clarity in testing is crucial in producer-consumer relations. This collective document will assist in improving the understanding of leaching from a variety of sources and will, where appropriate, help to bring together the approaches used in different technical fields and in different countries.
Hardbound. The Chernobyl accident drew attention to the difficulties of understanding the dynamics of radionuclide transport through the environment using older methods developed after the pseudo steady state pollution resulting after the weapons testing fallout. More recent approaches, which are reported in this book, have incorporated both the dynamic aspects highlighted by the pulse Chernobyl input and the importance of improvement in models that can be brought about by constraining parameters on the basis of a knowledge of the fundamental physics, chemistry, biology and ecology of the ecosystems involved. The papers within this volume include hydrodynamic models of suspended solids transport, ion exchange interpretation of radionuclide sorption: approaches applying a knowledge of membrane transport kinetics to the uptake of radionuclides by biota; the effects of different ecological niches on the relative uptake of radionuclides by different species;
