Cultural Heritage Environments: Monitoring Strategy for Preventive Conservation of Cultural Assets and Human Health Protection
Bibliographic record
Abstract
Objects of historic artistic value, conserved in indoor deposits or exhibited inside museum halls, are strongly influenced by the environmental parameters, as temperature, relative humidity and light quality. Environmental parameters directly impact the structural integrity of constitutive materials and promote microbial colonization on artwork surfaces, leading to biodeterioration. In cultural heritage dedicated environments (CHE), the microbial load may exist both on art works surface and in the environmental aerosol (bioaerosol), maintaining a unique balance. In this study, through a multi-phasic approach the presence of bacteria and fungal colonies in the aerosol and artifacts surface, of an exposure hall, have been investigated. This study defined specific, non-invasive procedures to sample microbial colonies, spread both on artworks surface and in the aerosol of dedicated indoor environments. Results from morphological analysis (microscopy, in vitro culture) and molecular investigation (microbial genomic DNA), provided useful information on the composition of the microbial consortia, allowing a complete understanding. Microorganisms, in addition to inducing artifacts biodeterioration are able to produce and release, in the aerosol (bioaerosol) of surrounding environment, biological particles and molecules (spores, cellular debris, toxins and allergens), potentially dangerous for the health of operators and visitors. The complete understanding of the consortia is peculiar to counteract the microbial colonization, also performing green strategies.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
