Chemometrical evaluation of multispecies-multichemical data by means of graphical techniques combined with multivariate analyses.
A new method combining graphical displays with principal component analysis has been used to evaluate published data on the toxicity of seven chemicals to 14 species (17 testing procedures) of aquatic biota. The results reflect the usefulness of simple graphical approaches for analyzing the structure of environmental data sets. Thus, the study indicates the importance of end point selection and underlines some relationships among the species and chemicals.
