Multi-analyte analysis of samples from moisture-damaged indoor environments detected both bacterial and fungal secondary metabolites in the sampled materials.

What they studied

Sixty-nine samples of building material and dust from moisture-damaged indoor environments.

Analysis by liquid chromatography–tandem mass spectrometry targeting 186 microbial secondary metabolites.

Comparison of metabolites found in wet versus non-damaged structures.

What they found

The authors reported that every sampled material tested positive for at least one of the targeted metabolites.

Streptomyces-associated compounds including valinomycin were reported only in samples from wet structures.

Bacterial and fungal metabolites were reported to occur together in the damaged samples.

What it does not establish

Material and dust sampling; airborne concentrations and inhaled dose were not measured.

Detection of a metabolite does not establish an exposure level or a health effect.

No occupant health outcomes were assessed.

This entry reports the study. It is not a statement about any building Sage Co. designs or constructs.
