| Abstract: | Qualitative and quantitative studies of the kinetics and dynamics of technogenic migration of heavy metals (HMs) have been
performed in laboratory experiments. It is shown that the redistribution of HMs applied into soils in neutral form has an
impulsive pattern. Soil texture does not have a decisive influence on the migration capacity of metals. An important feature
of the technogenic migration of HMs is the effect of the polymetallic contamination, upon which the migration capacity of
a set of heavy metals is higher than that of separate metal compounds. An index characterizing the ratio of absolute values
of migration rates of ionic forms of metals estimated from electrical conductivity values to the rate of infiltration of the
soil solution (vm/vf) is suggested to estimate the kinetics of HM migration in soils. |
