It was experimentally establishedthe changing of migratory activity of pollutants from building materials derived from blast furnace slag, during their life cycle in the form of non-linear wave-like character while newly opened contact surfaces with aggressive waters appearedduring the gradual crushing of materials as a result of destructive mechanical effects on them and effect of aggressive waters with varying pH values. The regularities of the migration activity of pollutants (for example,

It is shown the expediency of amending the order of the sanitary-hygienic assessment of building materials with the addition of industrial waste (Methodological Guidelines МУ 2.1.674-97 "Sanitary-hygienic evaluation of materials with the addition of industrial waste" RU), allowing to take into account the migration of pollutants from them during the life cycle.
