There is experimentally established the change of the migratory activity of pollutants from building materials produced from blast furnace slag throughout their life cycle in the form of a nonlinear wave-like nature as there are appeared newly opened surfaces of a contact with aggressive waters in the process of gradual crushing of materials as a result of destructive mechanical effects on him and corrosive waters with varying pH values. There are established regularities of the migration activity ofpollutants (on the example of heavy metals) as directly dependent on the newly opening surface of the contact of the material with water having a various pH value. There is shown an expediency of introduction of alterations in the procedure for sanitary hygienic assessment of building materials with the addition of industrial waste (Methodical Instructions 2.1.674-97), allowing to take into account the migration of contaminants from them throughout the life cycle.
