The project aims to study and develop, both
theoretically and experimentally, the current approaches to remediation of
soils polluted with heavy metals. The previous investigations concerned the
changes of forest soils (http://soil.msu.ru/projects/acidification;
http://soil.msu.ru/projects/pollution)
and soil solutions (http://soil.msu.ru/projects/solutions)
under air pollution impact. In the present study, a review of the current
remediation technologies is provided, as well as an update of new methods
under development with potential use under the defined problematic.
The most widespread remediation technologies for metal contaminated lands
include excavation and disposal off site. Nowadays, sorption based methods
appear to be one of the techniques, currently tested, to clean metal pollutants
from the soil. Potentially applicable sorbents are identified based on the
specific pollutant source and ground characteristics in the area. To characterise
the sorbent adsorption properties batch adsorption experiments with different
kinds of sorbent materials are conducted. The tested sorbents include natural
materials, waste materials from industry and agriculture, biosorbents, and
innovative sorbents. The most suitable ones will be further used in laboratory
and field experiments. The influence of different sorbents and other ameliorative
substances on mobility, phytoavalability and phytotoxicity of heavy metals will
be investigated. Potentialities and constraints of different approaches for
remediation of heavy metal polluted soils will be analysed.

Field work:
| |
The main attention is paid to polluted soils
in the vicinity of the major emitters of heavy metals in northern Europe -
the nickel-copper smelters Pechenganikel and Severonikel in the Kola Peninsula.
For comparison, a large number of soils with different texture, acidity and
content of organic matter, amorphous iron and aluminium oxides are investigated
in the taiga zone of European Russia.
