A comparison was undertaken of two techniques for measuring settled dust in water-damaged single-family homes, multi-family homes, public buildings, and schools. One technique utilizes PVC or MCE cassettes and a portable vacuum pump; the other uses a vacuum cleaner to capture dust in allergen filter bags. Preliminary results indicate poor correlation between the two different types of settled dust sampling techniques in terms of number of spores recovered per gram of collected settled dust. Species distributions as measured by rank order analysis appear to be better correlated.
