Microbial Volatile Organic Compound Emission Rates and Exposure ModelAirPollution Prevention and Control Division, US Environmental Protection Agency
Center for Engineering and Environmental Sciences, Research Triangle Institute, Research Triangle Park, N.C., USA This paper presents the results from a study that exam ined microbial volatile organic compound (MVOC) emis sions from six fungi and one bacterial species ( Strepto myces spp.) commonly found in indoor environments. Data are presented on peak emission rates from inocu lated agar plates loaded with surface growth, ranging from 33.5 µg.m-2 per 24 h (Cladosporium sphaerosper mum)to 515 µg.m-2 per 24 h (Rhodotorula glutinis). Fur thermore, changes in MVOC emission levels during the growth cycle of two of the micro-organisms are exam ined. This report also includes a calculation of the impact of MVOC emissions on indoor air quality in a typical house and an application of an exposure model used in a typical school environment.
