Background: When workplace air monitoring is not sufficient to determine the exposure levesl, the determination of compounds and some metabolites in exhaled air and personal exposure levels is considered a practical method for biological monitoring. The aim of this study was to determine the relationship between the concentration of tetrachlorethylene in exhaled air and personal exposure levels  in the dry cleaning workers

Methods: In this cross - sectional study, were collected exhaled air and personal exposure of Time Weighted Average (TWA) samples of 12 dry cleaning workers. Also the ambient air samples were study simultaneously.  Measurement of tetrachlorethylene in the exhaled air was performed using GC-FID through an incorporation of 1003 and 3704 NIOSH methods and optimization of analysis parameters.

Results: In this study, the personal exposure levels and tetrachlorethylene concentration in exhaled air of workers were above from the recommended national occupational exposure limits (OEL-TWA), and biological exposure index (BEI) respectively. The results showed that there is a significant relationship between the concentration of tetrachlorethylene in exhaled air and personal exposure levels (r=0.66 , P<0.05). Also, was obtained the significant relationship between the concentration of ambient air with exhaled air concentrations (r=0.59 , P<0.05), and personal exposure levels (r=0.91 , P<0.05) respectively.
