Airborne macrocyclic trichothecene mycotoxins measured in water-damaged indoor environments
Air sampling in water-damaged buildings detected macrocyclic trichothecene mycotoxins, with concentrations reported to rise during simulated occupant activity.
How to read this
This library reports what studies found. An entry describes a study's design, its findings in its own terms, and its limits. Nothing here is a claim about what a Sage Co. home does, delivers, or prevents.
Last reviewed August 30, 2026.
What they studied
- Air sampling in seven water-damaged buildings with documented Stachybotrys chartarum growth.
- Analysis of airborne particulate for macrocyclic trichothecenes by immunoassay and mass spectrometry.
- Sampling under still conditions and during simulated disturbance such as walking and HVAC operation.
What they found
- Airborne macrocyclic trichothecenes were detected at concentrations reported up to 1,300 picograms per cubic meter.
- Toxins were reported on particles smaller than intact spores.
- Simulated occupant activity was reported to increase measured airborne concentrations.
What this study does not establish
- Seven buildings selected for known contamination; not a representative sample.
- No occupant health outcomes were measured.
- No health-based exposure limit exists for these compounds against which to interpret the concentrations.
- This entry reports the study. It is not a statement about any building Sage Co. designs or constructs.
