The air inside living quarters and public utility buildings or the interiors of public transport vehicles, as well as the relationship between the internal and external sources of particulate matter (PM) and gaseous pollutants, have underwent sufficient research. On the other hand, non-production rooms, i.e., offices, restaurants, beauty salons, etc. remain very poorly recognized in this respect. For the above reasons, the aim of this work is to determine the difference in the total dust (TSP) and respirable PM (PM4) concentrations in selected rooms, i.e., offices and beauty centers, in relation to their outdoor concentrations. They were measured at six locations in accordance with the standard for the conditions at workplaces by means of PM aspirators. Indoor concentrations of TSP and PM4 were much higher than those in the external surroundings of the facilities. There were no significant relationships between the TSP and PM4 concentrations inside and outside tested rooms. Although the characteristic of the internal PM essentially depends on the characteristics of the external PM migrating to the interior of the premises, considering some types of non-production premises, internal emissions fundamentally changed the characteristics of PM.<\/jats:p>","DOI":"10.3390\/ijerph191610289","type":"journal-article","created":{"date-parts":[[2022,8,18]],"date-time":"2022-08-18T21:39:21Z","timestamp":1660858761000},"page":"10289","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Particulate Matter Concentration in Selected Facilities as an Indicator of Exposure to Their Service Activities"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0772-2922","authenticated-orcid":false,"given":"Patrycja","family":"Rogula-Kopiec","sequence":"first","affiliation":[{"name":"Institute of Environmental Engineering, Polish Academy of Sciences, 34 M.
