Pollution in the environment is measured as a combination of changes in chemical concentrations, physical conditions and biological systems. By using multivariate methods on the data obtained from extencive measurement programs the environmental analyst attempts to accomplish three objectives; Phenomena-description (representivity), Dimension-reduction (interpretability), and increased Resolution (sensitivity). Three different problems are used to illustrate the use of multivariate methods in envirometrics. The three applications are: 1) Multivariate correlation patterns of alkyl-homologue series, 2) Composition Activity Relationships (CARE) and 3) Multivariate Ecotoxicological Mapping (MEM). |
