Abstract
Styrene is a compound commonly used in several industries, especially in those
that manufacture glass-reinforced products. A thermal desorption-gas
chromatography-mass spectrometry method for determination of styrene in
industrial indoor and outdoor air is presented. Split valves of the thermal
desorption unit were fixed at flows of 150 mL/min for indoor air and 5.3 mL/min
for outdoor air, which regarded detection limits of 1.21 and 0.08 ng of adsorbed
compound, respectively. The method was checked at a fibreglass boat manufacturing
workshop. Samples were taken by diffusive and active sampling. Both methods were
applied to outdoor samplings with similar results, while indoor samples were taken
by diffusive sampling. Results confirm industrial activity as main styrene source
in the workplace studied and its surrounding area.
Key words: Diffusive sampling -- thermal desorption -- styrene: Tenax TA -- occupational exposure -- source emissions.
