Bioindykacja zanieczyszczeń powietrza w strefie oddziaływania Płockiego Zespołu Miejsko-Przemysłowego

Qualitative studies on the heary metals supply to the ground are important for evaluation of the ecological threat. This kind of research has been performed in the vicinity of Płock Urban-Industrial Complex of the scientific staff of the Mazovian Geographical Observatory of the Faculty of Geography and Regional Studies. The intensity of Pb, Cu, Cr, Cd, Ni accumulation in the moss (Sphagnum fuscum) has been observed. The moss samples collected from the natural environment were exposed on the influence of polluted air. The meteorological parameters in the place of exposition were measured accuratly. The relationship between metals concentration and wind frequency and velocity as well as the distance of sample from the pollution source gave the basis for the model are the meteorological conditions within specific time interval.
