The study is about variations in Carbonyl compounds concentration within apartment buildings according to pre-residence and residence.
We consecutively investigated indoor air pollutants in 120 households in 6 cities at pre-residence and residence. Carbonyl compounds were collected using the 2,4-DNPH cartridge and were analyzed using HPLC. The carbonyls concentration of indoor air in the new apartments before occupation measured formadlehyde(76.0㎍/㎥), acetone(85.9㎛/㎥), acetaldehyde(13.8㎍/㎥). The carbonyls concentration of indoor air in the new apartments after occupation measured formadlehyde(233.1㎍/㎥), acetone(128.9㎍/㎥), acetaldehyde(29.8㎍/㎥), respectively.
As a result, the mean concentration of carbonyl compounds within the pre-occupancy stage was lower than those of residence.
