Abstract—The contents of sulfur and its forms, as well as the levels of soil pollution by technological sulfur
with time in the Astrakhan and Mednogorsk regions are considered. A certain increase in the general back-
ground of a sulfur component and in the level of soil pollution by technological sulfur are observed in the area
of the Mednogorsk integrated plant, which has been operating for more than 50 years, as compared to the area
of the Astrakhan integrated plant, which has been operating for no more than 10 years. It is shown that, if
planned amounts of sulfur dioxides are emitted into the atmosphere, polluted soils (within 1–2 years) restore
their natural background of sulfur component rather quickly.
