Metal accumulation in urban ecosystem plantsAbstract
The paper presents the results of a study of metal accumulation (Cu, Zn, Mn, Sr, Ni, Ca, Fe, Br, Rb) in the leaves of trees, shrubs, and herbaceous plants (a total of 22 species) in the urban environment of Kaliningrad. The study area includes major geochemical landscapes – residential, industrial, and recreational districts. The background concentration of metals in plants is studied. The study establishes the presence of significant anthropogenic sources of metal pollution of vegetation in Kaliningrad. The leaves of plants found in the urban environment show excessive background concentrations of iron, manganese, zinc, and strontium. The maximum content of pollutants in plants is registered in industrial areas with high traffic load. Species-specific features of metal accumulation are established. Plants with a high metal accumulation capacity can be used in the phytoremediation of polluted urban areas.
