Associate Professor V.V. Oschapovsky wrote and published a textbook "Fundamentals of Ecology: Environment and Technogenic Impact", approved by the Ministry of Education and Science of Ukraine, recommended for cadets and students studying at higher education institutions, including the Ministry of Emergencies of Ukraine. Professor Mikhalichko B.M. wrote a large modern textbook "Course in General Chemistry. Theoretical Foundations."



      In total, more than 40 methodical instructions for laboratory, module control and calculation work have been developed by the department staff. Including, developed and published training manuals "Collection of problems and exercises in chemistry. I. General chemistry "(B.M. Mikhalichko, A.M. Shcherbina, V.V.
