Exposure to culturable and total microbiota in cultural heritage conservation laboratories.

Objectives: To date, the scientific source materials usually focus on microbial contamination of the museum or library collections themselves, while the exposure of persons who professionally deal with this type of objects in cultural heritage conservation laboratories is ignored.

Material And Methods: The study was carried out in 9 naturally ventilated conservation laboratories with no history of water damage. Viable (understood as culturable) bioaerosol stationary samples were collected in both outdoor and indoor environments using 6-stage Andersen impactor.

[Workers' exposure to selected biological agents in libraries of Upper Silesia].

The aim of this study was to assess the exposure of library workers to biological agents based on quantitative and qualitative characteristics of airborne and settled dust microflora supplemented with the analysis of dust mite allergens. The bioaerosol sampling was carried out using a 6-stage Andersen impactor. The settled dust samples were collected from book covers using cotton swabs and vacuum cleaner.
