COMPREHENSIVE ASSESSMENT AND RISK MIGRATION ABILITY OF HEAVY METAL CONTAMINATION OF SOIL AND VEGETATION COMPONENT SYSTEMS ^{[№ 13 ' 2015]}
In this paper, when considering the transport processes and substances such as heavy metals in the components of soil-plant systems assumed that this process is probabilistic in nature. The second assumption we adopted the current status of the independence of the system components from its previous state. This allowed us to consider the soil-plant system as a Markov chain with a finite number of states. The probabilities of a state determines the intensity of transitions substances system components. On the basis of the constructed mathematical models to calculate the risk of contamination of the soil, aboveground and root systems of plants with heavy metals. The risk of contamination of components of soil-plant system shows the likelihood that heavy metals accumulate in the soil, the root system and aboveground plant parts. The intensity of transition shows the magnitude and direction of transport of substances (heavy metal) the components of the system. Integral indicators characterize the overall distribution of heavy metals in the soil-plant-specific system. The differential indicator shows the distribution of one or the other metal in the soil-plant system.
