A survey of building material samples from water-damaged buildings reported that a majority tested positive for at least one mycotoxin.

What they studied

One hundred building material samples collected from water-damaged buildings in Sweden.

Analysis by liquid chromatography–mass spectrometry for a panel of mycotoxins.

Substrates included gypsum, wood, and other common construction materials.

Sixty-six percent of samples were reported positive for at least one mycotoxin.

Trichothecenes, sterigmatocystin, gliotoxin, aflatoxin B1, and satratoxins G and H were among those detected.

Detections were reported across a range of substrate types.

Material sampling; airborne concentrations and occupant exposure were not measured.

Samples came from buildings investigated for damage, not a random sample.

Presence of a toxin in material does not establish inhalation exposure.

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