modifications), which will possess most traits of plants suitable for phytore-
mediation. Our knowledge about the theoretical basis of biochemical plant response
and genetic traits in response to presence of metals in connection with practical
experiments will be one of the most significant factors affecting fast development of
phytoremediation. Apart from the plant itself, it will also be essential to properly
adapt plants to substrate conditions, moisture content as well as their ready appli-
cability. It is evident that in the search for new strains of bacteria and fungi the
above described objectives may be attained, in this way contributing to an increase
of plant biomass, which will constitute a significant factor in the selection of the
decontamination method of polluted soil. Due to the simultaneously conducted
work on biological and technical methods, we may expect successive studies
combining both types of methods. Such a combination will make it possible to
significantly reduce costs of the method connected with the application of technical
measures and at the same time will facilitate a shortening of time needed to attain
required effectiveness of the soil remediation process. The last, but not the least
concern is associated with the issue constituting a favourite argument for opponents
of biological methods, which is the claim concerning the impossibility of further
utilisation of plant materials containing considerable amounts of heavy metals. It
may be assumed that such methods as phytomining or combustion of contaminated
biomass in specially designed furnaces may solve this problem.
