Background and objective: 1,3-Butadiene has wide industrial application with main focus on production of butadiene-based polymers. The accurate determination of 1,3-butadiene is complicated by its high volatility. The aim of this study was to develop the method for determination of 1,3-butadiene migrated from butadiene-based polymers to air and water based on thermal desorption–gas chromatography–mass spectrometry. Methods: Purge-and-trap method was used for transferring analyte from water to gas phase followed by trapping on multi-bed sorbent tube (Carbopack B+X). Conclusions: The calibration plots for air and water with coefficients of determination R 2 > 0.99 were obtained in ranges 2–20, 10–200 and 50–1000 ng. The limits of detection and quantification of 1,3-butadiene were 0.02 ng and 0.06 ng, respectively. The accuracy of the developed method expressed in spike recoveries was in the range from 92 to 101% for air, and from 94 to 95% for water, with relative standard deviations below 10% for both matrices. The developed method was successfully applied for determination of 1,3-butadiene migration level from personal protective equipment (shoes) to air and water. The concentrations of 1,3-butadiene migrated to water and air were 0.044 µg L−1 and 0.91 µg m−3, respectively. Graphic Abstract: [Figure not available: see fulltext.].
