This work is dedicated to the theoretical and applied aspects of using computational methods to understand and predict the behavior of environmental chemical pollutants. Using chemo- and bioinformatics technologies, as well as modern methods of theoretical chemistry, scientific foundations have been developed for predicting the chemical, biological, and physical properties of chemical compounds, which ultimately determine their environmental and human health hazards.

The research was conducted in the following main directions:

  • Development and advancement of methodologies for using machine learning methods, quantum chemistry, molecular mechanics, and dynamics to solve various "structure-property" tasks, particularly for chemical pollutants.
  • Application of the developed approaches (in particular, hierarchical QSAR technology based on the simplex representation of a molecular structure, quantum-chemical approaches for modeling the kinetics of multistage organic reactions) to create adequate models that ensure effective prediction and virtual screening of the toxicity of various substances (including those for military use), analysis of toxic action mechanisms, and study of possible degradation reactions of toxicants.
  • Considering that the environmental hazard of substances depends not only on their toxicity but also on their ability to spread and penetrate different environments (soil, water, air, living organisms), properties such as water solubility, lipophilicity, bioavailability, the ability to penetrate various biological barriers, and specific interactions with biomolecular targets were studied, modeled, and predicted.
  • Summarizing the results of fundamental research, several computer expert systems were created for predicting and experimentally screening various substances (including military ones) concerning their potential environmental hazards. These expert systems have a user-friendly interface and are suitable for use by interested specialists from different fields with basic computer skills.

This comprehensive system for analyzing and predicting the danger of chemical pollutants has no analogues in Ukraine or the world.
