ABSTRACT
The aim of this study was to present the effectiveness of the proposed sample preparation procedure coupled
with the spectrophotometric technique for the determination of formaldehyde in saliva samples collected
from heavy, moderate, and passive smokers. Formaldehyde levels were determined in saliva samples collected
from smoking and non-smoking individuals. Formaldehyde was found in about 60% of the samples analyzed,
with concentrations ranging from 0.31 to 94 μg/g. The results confirmed the significant effect of tobacco
smoking on formaldehyde levels in saliva samples.
