Opis:: Floristic composition in three industrial areas with soils contaminated by heavy metals (As, Cd, Cu, Hg, Pb, Zn) and organic pollutants (polychlorinated biphenyls) was studied. The content of Pb was only significantly correlated with the floristic composition and explained 13.8% of its variability considering spatial dependency of the sites. No correlation was found for PCBs. Altogether, 237 plant vascular species were found at three study sites (117, 133 and 105, respectively). The three study areas differed in their species composition represented by their own characteristic species. The gradient in the content of natives/non-natives, species number, prevailing life forms and indicator values for plant species investigated was revealed. Based on our results, for phytoremediation purposes we can select productive plant species with high biomass and ability to accumulate large amounts of heavy metals or organic compounds and surviving on soils with low mineral content.

Opis:: The aim of the study was, to find out whether the occurrence of Rhytisma acerinium and the variability of numbers of the "tar-spot" fungus on Acer platanoides leaves depend on the degree of environmental pollution. A significant variability was found between sites in relation to contents of chemical elements in soils, leaves and numbers of "tar-spots". The similarity of sites presented in dendrograms classified them as industrial, urban-agglomeration and vehicle-transport areas. The factor and PCA analyses showed that two factors differentiate the soil of the sites in respect of Fe, Cu, Co, Mo, Cr, Ni, Cd and N, S, Mn, Pb. In case of leaves of A. platanoides populations differentiate them in respect of N, S, Fe, Pb, Zn, Co, Be, Cr, Cd and Mn, Cu, Mo. The different air pollutions affect significantly the numbers of "tar-spots" on leaves. Sites with the highest contents of elements do not show "tar-spots", and the factors restricting their occurrence are the high contents, mainly of N, S (NOX, SOX) and heavy metals. In sites, with the lowest contents of these elements massive infections take place. The occurrence of R. acerinium corresponding with the level of site pollution can be used as a tool for evaluation of the degree of environmental pollution.

Tytuł:: Self-organizing feature maps and selected conventional numerical methods for assessment of environmental quality

Opis:: The investigations concerned sites of Acer platanoides L. infected or not by Rhytisma aceriniu (Pers.) Fr. The aim of the study was to check the occurrence of R. acerinium, and whether it reflects the environmental status. Furthermore, an analysis was carried out to find out whether the applied SOFM offers additional advantages to solve problems in relation to conventional methods. Concentrations of selected elements in soils and leaves, and leaf and "tar-spot" morphometric traits were also measured. A significant differentiation was found between sites in relation to the analyzed traits. It appeared, that sites showing lower concentrations of chemical elements and proper developmental habitat conditions massive infections take place. The study showed that R. acerinium is a good biological indicator for assessment of environmental status. The applied, conventional statistical methods, SOFM and image techniques showed similar, but not identical results for assessment of environmental quality using R. acerinium. SOFM appeared to be more useful for ordination of results and ought to be taken into account as a proper tool of estimation of various plants and their biotopes.
