METHOD OF IDENTIFYING HAZARDS AND PREDICTING THE EMERGENCY SITUATIONS IN CASE OF SOIL CONTAMINATION BY HEAVY METAL COMPOUNDS

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