Abstract:
Introduction. The risks of the chemical warfare agents use are currently very acute as a result of the ongoing armed aggression of the russian federation against Ukraine. Chemical warfare agents were ϔirst used during the First World War. In September 1914, the German army, neglecting the agreements of the Hague Conferences of 1899 and 1907, involved artillery chemical shells with irritating toxic substances in hostilities.The purposeof the study was to analyze the frequency of use of chemical warfare agents by the russian federation against servicemen of the Armed Forces of Ukraine and to determine trends in the use of chemical weapons during full-scale aggression.Materials and methods. In the course of the study, we resorted to general scientiϔic theoretical methods, such as the bibliographic method, methods of system analysis, information synthesis and generalization. The study used open (Internet) materials of the General Staff of the Armed Forces of Ukraine etc on the cases of chemical warfare agents used by the enemy. We also built trends, calculated equations and values of reliability of the approximation of the obtained trends in the frequency of use of chemical warfare agents by the army of the russian federation against servicemen of the Armed Forces of Ukraine by months since December 2023 to December 2024 inclusive.Results.Since December 2023 to May 2024 inclusive, there was a tendency to increase the number of uses of the above-mentioned weapons by the russian army against servicemen of the Armed Forces of Ukraine – from 81 registered cases in December 2023 to 715 recorded cases in May 2024, which was 8.83 times more than in December 2023. This trend is reliable, since the value of the reliability of the approximation of the obtained trend is R2 = 0.9227 and is in the range of 0.8 to 1.0, which indicates a high degree of reliability of the constructed trend line and its equation.Conclusions. Damage to the servicemen of the Armed Forces of Ukraine by combat poisonous irritating substances, in most cases, was of mild and moderate severity. Medical care was provided to the victims mainly on the spot, as a rule, they did not need to be evacuated to the next stages of medical evacuation
