The environmental impacts of acid rain: on human health, on buildings and materials, on forests, freshwaters, crops and biodiversity and on global warming have been well-documented. Less is known about the extent and economic costs of these impacts. This book describes the first major implementation of an integrated scientific and economic assessment of the consequences of acid rain. It provides an extensive data review and examines how this unique approach to assessment modelling can be can be used to calculate an acidification cost per unit of pollutant in monetary terms. Part One focuses on the methodological issues of scientific measurement of acidification, dose-response relationships and economic approaches to acidification control. Part Two looks at the environmental impacts and economic consequences of acidification. Affected environmental media and human health are investigated in separate chapters, each including both scientific and economic analyses. Part Three provides a summary of the findings and makes recommendations for further application of these types of results to policy actions.

This title was first published in 2002: The adoption of the 1999 Gothenburg Protocol within the Convention on Long-Range Transboundary Air Pollution (CLRTAP) and the 2001 EU National Emission Ceilings (NEC) directive has made for much stronger European air pollution policies. This volume offers the first in-depth analysis available of this key development. Central questions discussed include: -What role did the three new Green member states joining the EU in 1995 play in this development? -Will these significantly stronger policies only be followed by weaker implementation? -Why are the EU emission ceilings more ambitious than those of CLRTAP? -Do these more ambitious EU NEC emission ceilings and wider trends such as EU enlargement signal that CLRTAP is fading away as a central forum for European policy development? Decision makers, negotiators and international and non-governmental organizations will benefit from this book as it discusses important institutional issues. Students and academics will also find it extremely useful.

AND CONCLUSIONS OF THE WARSAW II MEETING ON ATMOSPHERIC COMPUTATIONS TO ASSESS ACIDIFICATION IN EUROPE JOSEPH ALCAMO and JERZY BARTNICKI International Institute for Applied Systems Analysis Schlossplatz 1, A-2361 Laxenburg, Austria (Received June 1, 1988; revised June 20, 1988) Abstract. Three topics are discussed in this report: sensitivity/uncertainty analysis of long range transport models, the interface between atmospheric models of different scales, and linkage between atmospheric and ecological models. In separate analyses oflong range transport models, it was found that uncertainty of annual S deposition was mostly affected by uncertainty of wind velocity, mixing height and wet deposition parameterization. Uncertain parameters collectively caused S deposition errors of around 10-25% (coefficient of variation) in the models examined. The effect of interannual meteorological variability on computed annual S deposition was relatively small. Different methods were presented for combining models of regional and interregional scale. It was found to be more important to include interregional information in regional-scale models for annual computations compared to episodic computations. A variety of linkage problems were noted between atmospheric and ecological models. The vertical distribution of pollutants and 'forest fittering' of pollutant deposition were found to be important in ecological impact calculations but lacking in the output of most interregional atmospheric models.
