Abstract
|
|
|
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 μg/m3), acetone(85.9 μg/m3), acetaldehyde(13.8 μg/m3). The carbonyls concentration of indoor air in the new apartments after occupation measured formadlehyde(233.1 μg/m3), acetone(128.9 μg/m3), acetaldehyde(29.8 μg/m3), respectively.
As a result, the mean concentration of carbonyl compounds within the pre-occupancy stage was lower than those of
residence.
