Abstract
In accordance with sustainable development goals (SDG’s), urgent action should be taken to make the societal and natural environments better for human beings. People spend most of their time indoors, therefore growing attention is devoted to address indoor air pollution. When the sources of anthropogenic indoor air pollution (copiers, laser printers) are operated indoors, then chemical and physical indoor air pollution may be higher than air pollution outdoors. Ozone, aerosol particles and volatile organic compounds are the result of pollution caused by copiers and printers. The research was carried out in a copying room by recording chemical (ozone and aerosol particles) and physical (noise) environmental pollution. To determine instantaneous ozone concentrations in the copying room, an ozone analyzer O3 41M was used, while to evaluate the effect of ozone on the ambient air of the copying room, passive samplers were used. To determine the number and concentration of aerosol particles in the ambient air of the office, a particle counter AZ-5 was used. In addition, a DrDAQ data logger was used to measure noise emitted by the copier and ambient temperature as well as relative air humidity. It was found that the distribution of ozone and aerosol particles in the copying room was mostly determined by the copying intensity. The maximum concentration of ozone and aerosol particles was determined during automatic copying (91–120 copies/min).

In order to find out the dominant aerosol particle size during the technological process, the spectrum of aerosol particles (0.4–2.0 μm) was investigated with an aerosol particle counter AZ-5
The obtained research data show that the most significant changes were observed in the concentrations of tiny aerosol particles in the room during the technological process, while the changes in the concentrations of particles with an aerodynamic diameter of more than 0.7 μm in the copying room were insignificant
Summary
Received: 2 December 2021Social sustainability could be achieved through the proper management of different systems, processes, organizations, and activities. Among the topics covered by the umbrella of social sustainability are health and social equity, human rights, social responsibility, product responsibility as well as decent working conditions. Some of these are closely interconnected with the topics of environmental sustainability. The main indoor pollutants resulting from the copying process are ozone, volatile organic compounds, nitrogen oxides, aerosol particles [7,8,9]. Ozone concentrations in a premises without any ozone emission sources are approximately 250 times lower than its levels in ambient air due to ozone filtration through walls [13]. Ozone concentrations in a premises with operating copiers are in many cases significantly higher than outdoors
