Accumulation of heavy metals by soil and forest honeysuckle under different anthropogenic loads

The paper provides information on the accumulation of heavy metals (TM) by the root and shoot systems of forest honeysuckle Lonicera losteum L., growing along the Shchelkovsky highway (Shchitnikovo village) and the forest area of the Gorensky Forest Park. The coefficients of accumulation of trace elements in the aboveground and underground phytomass of forest honeysuckle near the highway are arranged in the following order: lead and cadmium: stem < flower < leaf < root; zinc: leaf < flower < < stem < root; iron: root < flower < leaf < stem; copper: flower < leaf < stem < root. The maximum amount of lead and cadmium accumulates in the stems; zinc in the leaves; iron in the roots; copper in the flowers. In the forest biocenosis, heavy metals formed the following series: lead and cadmium: flower < leaf < root < stem; zinc: root < stem < < flower < leaf; iron and copper: root < flower < leaf < stem. The factors contributing to the pollution of soils and plants within the urban environment and forest park are noted: motor transport, rail transport, construction, waste disposal.
