Indoor air exposure to aldehydes and ketones in rooms with new and old furniture of a new office building

The aim of this article was to evaluate and compare the levels of aldehydes and ketones
in indoor air of a new office building in rooms with new and old furniture. The sampling method
involved both passive cartridges and silica gel DNPH-coated tubes. Aldehydes and ketones levels
were quantified using a DNPH-derivatisation method followed by liquid chromatography coupled
to UV detection for 14 aldehydes and ketones. The results obtain showed that both active and passive sampling methods can be used for indoor air aldehydes and ketones assessment depending
on what you intend to achieve: long-term average or short-term monitoring. Results revealed that
higher concentrations of aldehydes and ketones were found in rooms with new furniture compared to
rooms with relative old furniture, making new furniture a possible source of aldehydes and ketones.
