【 摘 要 】

The article deals with the data on accumulation of heavy metals in the above-ground phytomass of common vegetation in urban ecosystems of Kursk. The accumulation of heavy metals by woody and grassy plants vegetating on soils of various genesis and structure of land-use experiencing contrast technogenic burden is studied. It is established that the priority element among heavy metals polluting plants is plumbum which exceeded limits of normal concentrations (norm) in 47% of samples which are taken in ecosystems of the city. Plants accumulators of manganese and zink are revealed. The proportion of the samples polluted by Pb in Tilia cordata Mill. in parks, squares and ecosites of Kursk reaches 100%. The role of two complex factors determining rates and volumes of deposition of plumbum in aboveground phytomass of common species of flora of Kursk is defined.
