Chemodynamics and Environmental Modeling

Partitioning of chemicals in the environment and its modeling is becoming an important field in environmental science and engineering. This book enables students, researchers, and interested laymen to enter the field of environmental modeling in a fast and effective way. The book contains modeling software (CemoS V 1.10), data sets and the CemoS handbook. Each chapter contains examples and exercises. The book is for those interested in modeling exposure to chemicals. It contains two parts: part one is the text book which allows the reader to learn about the dynamic behavior of chemicals in our environment. Basics of exposure estimation, mathematics and chemistry are explained in the first chapters, followed by a guide to exposure models for all environmental media. Part two is the software tool "Cemos" (Chemical exposure model System) which includes nine exposure models, a substance database with twelve data sets, data estimation routines, quality assurance tools and a hypertext online help. The disk is quickly installed and runs on DOS 3.3 or higher (up to WINDOWS NT). The comprehensive Cemos manual is also included. It is identical to the online help. All equations used in the program are described in detail, making the calculations fully transparent. Exercises with solutions, example calculations and a database help the reader to learn about and apply exposure models.
