The species of heavy metals in water of natural and technogenic soils of Kola Peninsula (Russia)

摘要

The comparative investigation's results of water of podzolic soils of natural (spruce and pine forests) and technogenic (environs of Cu-Ni smelter, Severonickel company) landscapes of Kola Peninsula are provided. The decrease of pH level on 0,6-0,9 units in the waters of polluted soils in comparison with the background ones and increase of the content of dissolved organic matter and content of ions Ca~(2+), Mg~(2+), SO4~(2-) in 1,5-3 times were estimated. The content of Cu and Ni increased in 7-30 times. More than a half of total content of metals in water are presented by negative charged particles, almost a quarter of them- by cations ( predominantly as simple ions), the another quarter- is presented by colloidal and non-charged particles.
