Dust fungi and endotoxin measured against respiratory symptoms in a water-damaged office building

Park J-H, Cox-Ganser JM, Rao C, Kreiss K (2006) · Indoor Air 16(3):192–203

In a study of occupants of one water-damaged office building, both fungal and endotoxin measures in dust were reported in dose-response association with respiratory symptoms, with an interaction between them.

What they studied

Eight hundred eighty-eight occupants of a water-damaged office building.

Floor and chair dust sampling analyzed for fungi, ergosterol, and endotoxin.

Questionnaire assessment of respiratory symptoms, analyzed by exposure quartile.

What they found

Dose-response relationships were reported for both endotoxin and fungal measures with respiratory symptoms.

The authors reported that endotoxin modified the association between fungi and symptoms.

Associations were reported to be stronger when both exposures were considered together.

What it does not establish

Cross-sectional study of a single building.

Dust measures are proxies for inhalation exposure.

Self-reported symptoms; no clinical diagnosis endpoint.

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