“…Ґрунти за рівнем засолення, який перевищує 75 %, стають практично непридатні для рослин усіх видів [22]. Акумуляція солей в поверхневих шарах ґрунтів призводить до деградації рослинного покриву і є однією з причин загибелі зелених насаджень у місті [23]. Обводнені території, пухкі водопроникні ґрунти в Україні сприяють проникненню молекул важких у глибину ґрунту.…”

Purpose. The goal of the article is to develop a method for identifying hazards and predicting the possibility of a technogenic emergency caused by the spread of compounds with heavy metals in the soil during long-term storage of galvanic sludge in open areas. Methodology. The method is developed on the basis of a mathematical model that allows estimating changes in the depth of distribution and level of soil salinity over time using initial information about soil structure and its characteristics (molecular diffusion coefficient, volume humidity), annual volumes and conditions of sludge storage in the enterprise. Restrictions are set: the presence of harmful substances on the soil surface with a concentration that exceeds the permissible level; inadmissibility of harmful substances to aquifers. Results. The practical use of the method made it possible to identify the main dangers and predict the possibility of an emergency situation with negative environmental consequences during long-term storage of galvanic waste in open areas. The dynamics of soil salinity levels and the depth of penetration of heavy metals increase over twenty years of conservation has been determined, as well as the possibility of hazardous compounds entering groundwater has been assessed. Originality. The non-linear, non-stationary mathematical model is based on the theory of physico-chemical hydrodynamics of cellular media. The process of motion of metal salts has been described by the differential equation of motion and conservation of mass of matter for vertical mass transfer of matter. Practical value. Formalization of information about the hazards arising during the storage of industrial waste with chemically active elements allows to consider the subject area as a complex dynamic system consisting of objects of different nature, the totality of which determines the level of danger of emergencies with environmental consequences. The developed method makes it possible to transfer the obtained results to decision-making support systems, predicting possible consequences and material costs associated with post-emergency measures, motivating the management to take measures in advance.
