Changes in the content of heavy metals in soils due to the application of waste from the pulp and paper industry

This paper presents the results of a study of changes in the heavy metals content of soils of Karelia (podzolic loamy and peats high moor). Waste from wood processing, pulp and paper industry was added to the soils as organic additives using sodium lignosulfonate as an example. The results showed that no correlation with the additive dose was found in the series of total (Fe, Mn, Cu, Zn, Ti, Al, Ni, Co, Cr, Cd, Mo) and available forms of metals (Cu, Zn, Ti, Al, Ni, Co, Cr, Cd, Mo). Nevertheless, there is a positive correlation between the total and available forms of Pb and the available forms of Fe and Mn (r = 0.9), which can be explained by their initial content in the industrial plant material. It should be noted that the content of all forms of the studied metals did not exceed the requirements of sanitary-hygienic standards and geochemical background typical for soils in Karelia.
