The study of the influence of the elemental composition of batteries on environmental parameters has been carried out. The authors propose to predict the states of ecosystem development on the basis of their studies in stationary and dynamic modes, the latter of which is based on the solution of systems of differential equations using the numerical Runge - Kutta method of the fourth order. The methodology of forecasting and modelling situations, mapping sources of risks and monitoring ecological changes allows to develop the corrective measures of ecological catastrophe prevention.

Based on the analysis of the results of the study of the multicomponent composition of waste batteries using an X-ray fluorescence analyser “EXPERT 3L” the indicators of the danger of their multicomponent composition were evaluated and corrected taking into account the proportion of each element of the studied batteries. The article describes the new approach proposed by the authors to assess the impact of multicomponent battery composition on the environment, the peculiarity of which is to determine the resilience of ecosystems on the base of mathematical modelling of the rates of the reactions of formation and removal of individual substances in the system. In particular, quantitative indicators of resilience and loss of natural ecosystems are analysed.
