MULTI-CRITERIA RANKING OF INDOOR AIR QUALITY IN NON-INDUSTRIAL ENVIRONMENTS

摘要

This paper reports the results of the characterisation and quantification of airborne polycyclic aromatic hydrocarbons and volatile organic compounds in non-industrial environments in an Australian city. The most abundant and most frequently encountered compounds include, nonanal, decanal, texanol, acetone, formaldehyde,acetaldehyde, toluene, hexanal, ethyl benzene, the xylenes and C3-benzene. The distribution of these and other compounds found in the buildings have been rationalised in terms of indoor activities and the building characteristics (distance from a major roads, floor materials, use of air extractors etc). In addition, multi-criteria decision making procedures have been employed to rank the buildings on the basis of forty indoor air quality-influencing variables. This approach offers a useful tool that could facilitate the identification of environments requiring attention, and assist the formulation and prioritisation of control strategies.
