ECOLOGICAL MONITORING OF SOILS IN THE «KIZHI» MUSEUM-RESERVE
2018
Akhmetova, G V
The results of ecological monitoring of soils in the Kizhi open-air museum and nature reserve carried out every 5-6 years since 1999 are reported. The findings concerning the chemical properties of the island’s soils (acidity, carbon and nitrogen content, cation exchange capacity) indicate that compared to the regional background these soils are noted for relatively high fertility and buffering capacity. These distinctions of the soils stem from the island’s unique natural conditions. Soils of the island were surveyed for heavy metals. Their levels in these soils proved to be elevated compared to the regional background, as dictated by parent rocks (shungitic moraine and schists). Analysis of the data from four monitoring stages revealed a downward tendency in the levels of such heavy metal as lead. On the other hand, there is a slight upward trend in copper and nickel concentrations.
