PREVALENCE OF POTENTIAL SOURCES OF INDOOR AIR POLLUTION IN U.S. OFFICE BUILDINGS

摘要

As part of its effort to collect baseline information about office buildings, the U.S. Environmental Protection Agency collected information on the prevalence of sources in or near 100 randomly selected office buildings in the USA. Indoor sources surveyed included special use areas (e.g., kitchenettes, parking garage, laboratories, print shops), cleaning product and pesticide use, renovation activities, water damage, and storage. Outdoor sources surveyed included nearby construction, heavy traffic, power plants, industrial stacks, emergency generators and trash dumpsters. For some sources, the frequency of use is also presented. These data can be used by as model inputs to estimate concentrations and exposure as well as be used to assist policy makers making decisions about which sources deserve attention.
