Metal accumulation in urban ecosystem plants

Abstract

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.

The human impact on the chemical composition of plants in large industrial centres: The case of the city of Gomel

Abstract

This article considers the features of heavy metal accumulation in individual plants of the true grasses and spurge families in two industrial areas in the city of Gomel and outside the city. The author analyses the heavy metal accumulation in the aquatic vegetation in the city’s waterways. It is shown that, in industrial areas, the Gramineae are charactersied by higher cadmium, barium, nickel, and molybdenum concentrations and the Euphorbiaceae by those of chromium. Aquatic plants show higher levels of heavy metal accumulation in comparison with meadow vegetation.
