(Видавництво Львівської політехніки, 2020-02-10) Popovych, Olena; Vronska, Nataliya; Yatchyshyn, Yuriy; Zaharko, Yaroslava; Lviv Polytechnic National University
The prospects of the pharmaceutical industry development are closely connected with scientific and technological progress. In Ukraine, handling hazardous medical waste is an open question. The rapid development of pharmacy in recent years has created and increased the possibility of the generation and accumulation of pharmaceutical waste at the enterprises and in the environment. Only a few enterprises deal with medical waste disposal. Medical waste recycling requires an extremely high level of attention and carries great risks associated with handling this medical waste. When medical waste is burnt, strong pollutants are released into the atmosphere – carcinogens, furans and dioxins from chlorine halogen compounds, namely dumping of the hazardous material that contains heavy metals, and is likely to cause bioaccumulative hazardous substances to transfer to the environment.
Influence of artificial acid rains on the soils of differentmechanical composition
(Lviv Politechnic Publishing House, 2017-03-21) Kovalchuk, Oksana; Malyovanyy, Myroslav; Popovych, Olena; Vronska, Nataliya; Lviv Polytechnic National University
Acid rain influence determination created on the basis of sulfuric, nitric acids and their mixture on the chemical properties of soil substrates of different mechanical composition.
Integrated adsorption and ultrasonic technology for water treatment processes
(Publishing House of Lviv Polytechnic National University, 2016) Vronska, Nataliya; Malovanyy, Myroslav; Koval, Iryna; Starchevskyy, Volodymyr
The aim of this work is to study the process of water purification from mechanical and chemical pollution and pathogenic microflora by adsorption and ultrasonic methods. Proposed technology reduces bacterial contamination and purifies water from organic pollutants, improving its quality.

Prospects of cleaning filtrates by aerobic-reagent method on the example of Lviv region
(Видавництво Львівської політехніки, 2021-06-01) Malovanyy, Myroslav; Zhuk, Volodymyr; Tymchuk, Ivan; Vronska, Nataliya; Zavoyko, Bogdan; Senkovych, Olha; Lviv Polytechnic National University
In 2021, the situation with the collecting, processing and disposal of waste in general, solid waste in particular, remains difficult in Ukraine and needs to be solved immediately. Soil contamination, as well as contamination of surface and ground waters by filtration effluents (or filtrates), is one of the most dangerous consequences of non-regulatory disposal of solid household waste.
Research of infiltrates content of landfills of hard domestic wastes (HDW) (on the example of Lviv landfill)
(Видавництво Львівської політехніки, 2017-12-23) Sereda, Andriy; Sliusar, Vira; Vronska, Nataliya; Malovanyy, Myroslav; Lviv Polytechnic National University
Work investigated composition of infiltrates of Lviv landfill HDW. An estimate is given of his influence on an environment and a microbiological analysis was conducted of the formed culture in infiltratу after pre-clean it by aeration.
Wastewater treatment by ultraviolet irradiation technique
(Publishing House of Lviv Polytechnic National University, 2017) Vronska, Nataliya; Malyovanyy, Myroslav; Popovych, Olena; Stokalyuk, Oleh; Lviv Polytechnic National University
Devoted to the problem of sewage treatment by ultraviolet radiation. This method can clear the water from microbiological contamination and thereby improve water quality.
