The major environmental concerns in the troposphere are the increasing burden of photo-oxidants on all scales, the acidification of soil and water, and the atmospheric contribution to nutrient inputs to ecosystems. This book assimilates the many scientific results from the EUROTRAC project about the state of the troposphere over Europe on local, regional and global scales, and presents them in a form suitable for use by those responsible for environmental planning and management in Europe. The findings and conclusions illustrate the complexities which face both environmental policy makers, seeking to find ways to abate pollution on a regional scale, and scientists, wishing to study and understand the scientific problems. This book is volume 10 of the series on Transport and Chemical Transformation of Pollutants in the Troposphere.

"This book presents a very good introduction to combinatorics. It covers most aspects of enumeration and order theory,... It is divided into three parts. The first part presents the basic material on mappings and posets... The second part deals with enumeration ... Finally the third part treats of the order-theoretic aspects ... In the text examples are given and at the end of each chapter valuable notes, also very good selected exercises. They constitute an organic part of the book. This book can warmly be recommended first of all to students interested in combinatorics. A two semester course can also be based on it." -Publicationes Mathematicae Debrecen
