In many scientific branches, and especially the environmental sciences, the need for data treatment and evaluation is increasing continuously. Therefore, the interest and application range of multivariate analysis have expanded accordingly with a view of structuring, interpreting, and evaluating complex data bases. In this context, the present volume attempts to review the state-of-the-art in multivariate analysis and give an overview of the various fields of application in ecology, environmental chemistry, toxicology, risk analysis, and structure-activity relationship (SAR) studies. The first chapters of the book are focusing on fundamental aspects of multivariate analysis. The second part contains a number of case studies, with the application of basic methods such as principal component analysis, correspondence factor analysis, discriminant analysis, and neural networks. This book reflects and combines the lectures organized in June 1991 in the frame of the Eurocourse programme at JRC Ispra under the sponsorship of the Institute for the Environment. It was the intention of the course and the resulting publication to promote and stimulate the application of multivariate analysis in environmental sciences and related areas. F.
