Aldehydes, acetone, formic and acetic acids in indoor air of an office building

One of the objectives of our study was to evaluate and compare the levels of aldehydes and ketones in
indoor air in offices. Also, we wanted to determine and discussed indoor concentrations of formic and
acetic acids in the same offices. As so, a total number of seventeen carbonyls were scanned in indoor air
samplers. Aldehydes and ketones were quantified using a DNPH-derivatization method followed by liquid
chromatography coupled to UV detection. For the determinations of formic and acetic acids, a fast ion
chromatography analytical method was developed. Results obtain showed the presence of the interested
compounds in all the sampling offices and also possible sources
