Comparison of biocontaminant levels associated with hard vs. carpet floors in nonproblem schools : results of a year long study

The aim of that study was to determine whether there was a quantifiable difference in biocontaminant levels between one school with a carpeted floor and another school with hard surface floor. During one year, air and floor dust samples were collected and analyzed. The results suggest that floor covering is not the major contributor to airborne levels of biocontaminants in nonproblem schools.
