VESPER, S. J. DEVELOPMENT OF THE EPA RELATIVE MOLDINESS INDEX© AND ITS RELATIONSHIP TO HEALTH. Presented at ASTM Conference, Boulder, CT, July 24 - 26, 2006.
Impact/Purpose:
1. Develop and publish a standard method or guidance document for QPCR analysis of microorganisms in environmental samples (air and water filtrates and dust).a standard method or guidance document for QPCR analysis of microorganisms in environmental samples (air and water filtrates and dust). Publication will involve a consensus standards organization. 2. Use QPCR methods to monitor childhood exposures to mold as a part of field studies, in order to establish whether a relationship exists between molds encountered in indoor environments and asthma-related health problems.
Description:
This study compared two binary classification methods to evaluate the mold condition in 271 homes of infants, 144 of which later developed symptoms of respiratory illness. A method using on-site visual mold inspection was compared to another method using a quantitative index of moldiness, calculated from mold specific quantitative PCR (MSQPCR) measurements on the concentration of 36 species of molds in floor dust samples called the EPA relative moldiness index© (ERMI©).
