Abstract
Legislative history of indoor air quality (IAQ) in China may be simply divided into three stages: starting stage (late 1970s-1993), developing stage (1994-2000), and normative management stage (2001-present). Up to date, China has established two sets of IAQ relevant standards: one set directly dealing with indoor air concentration limits, and the other dealing with limits of harmful substances contained in materials that will be used for constructing or furnishing the interior of buildings. This paper reviews the background, objectives, and approaches of various IAQ related standards in each of the three IAQ legislative (management) stages.
