This book is intended to serve as a comprehensive source for the advancements and contributions made in environmental transformation and transport modeling in general and the associated health risk assessment topics in particular. The selection of the title, "Environmental Modeling and Health Risk Analysis" stems from an ambitious objective of providing a review of air, surface water and groundwater quality modeling topics and linking these models with exposure and health risk analysis. Thus, the purpose is to provide the reader with an integrated perspective on these two seemingly distant fields. The ACTS and RISK software that is an integral part of this book include computational platforms for all models discussed in the book. Using these two software tools, available from http://extras.springer.com/, the models described in the book can be readily accessed and used in classroom or professional applications as demonstrated in the book.

Zusammenfassung
Environmental Modeling and Health Risk Analysis (ACTS/RISK) The purpose of this book is to provide the reader with an integrated perspective on several ?elds. First, it discusses the ?elds of environmental modeling in general and multimedia (the term multimedia is used throughout the text to indicate that environmental transformation and transport processes are discussed in association with three environmental media: air, groundwater and surface water pathways) environmental transformation and transport processes in particular; it also provides a detailed description of numerous mechanistic models that are used in these ?elds. Second, this book presents a review of the topics of exposure and health risk analysis. The Analytical Contaminant Transport Analysis System (ACTS) and Health RISK Analysis (RISK) software tools are an integral part of the book and provide computational platforms for all the models discussed herein. The most recent versions of these two software tools can be downloaded from the publisher's web site. The author recommends registering the software on the web download page so that users can receive updates about newer versions of the software.
