The problem of geographic landscapes has as basis the papers of the O.U.N. World Conference from Rio de Janeiro (1992) on Environment and Sustainable Development, but also the European Landscape Convention (Florence, 2000). The agreements reached at these events are applied across signatory countries in Europe and include natural, rural, urban and disturbed spaces, the main objective being the protection, management and planning of the degraded landscapes. In this paper there are presented some results of study of some chemical elements of anthropic origin spreading in soils of Tiraspol city. The city was and still remains one of the most industrialized cities of the Republic of Moldova. The industrial infrastructure leads to chemical pollution and appearance of sectors with increased content of heavy metals. Within city limits 8 anomalous centers were recorded with increased content of Co, on 65% of the surface the anomalies with increased Cu content are registered. Along the roads with intense vehicle traffic the Pb content overpasses the republic background. One of the most pollutant elements was and still is Zn, with the content between 600-8500mg/kg. The most polluted are the surfaces within the perimeter of industrial and transport enterprises. In the paper there are presented the results of current researches on geochemical pollution and quantitative dynamics from the last decades.

Key words: landscape, urban environment, soil, pollution, heavy metal.
