t is well-documented that carbonyl compounds have adverse effects on human health. On the other hand, theseoxygenated volatile organic compounds (OVOCs) are precursors of secondary pollutants such as troposphericozone or peroxy acetyl nitrate (PAN). In particular, formaldehyde, the simplest carbonyl, is the most abundant carbonyl in the air generated from the degradation of most volatile organic compounds (VOCs). This workpresents for the first time the characterization and determination of levels of carbonyl compounds by passivemonitoring performed from April?December 2021 in the city of Cordoba, Argentina, the second most populatedMediterranean city located in the center of the country. Annual concentrations, considering the 11 carbonylsmeasured, were in the range of 0.13?8.75 μgm􀀀 3. Formaldehyde and acetaldehyde were the carbonyls detectedin the highest annual average concentrations of 4.44 ± 1.75 μgm􀀀 3 and 3.85 ± 1.44 μgm􀀀 3, respectivel
