| Abstract: | The application of tree species (leaves) as biomonitoring devices is studies by the use of cluster analysis. It is shown that the chemical analysis of leaf samples should be accompanied by a careful chemometrical data treatment in order to obtain a reliable information on the behaviour of various tree species to heavy metal exposure (8 trees for three heavy metals in twelve different places) in fall and spring season. Additionally, the distribution of the sampling sites is studied by the same approach and a commentary on the urban aspects of sampling is given. |
