Abstract. A field study was carried out on 13 workers exposed to styrene vapors at time-weighted average concentrations between 10 and 73 ppm. The reactive intermediate styrene-7,8-oxide was determined in blood samples using a direct gas chromatographic method. Styrene-7,8-oxide concentrations were in the range between 0.9 and 4.1 μg/l blood. Linear correlations were found between styrene-7,8-oxide in blood and styrene in ambient air and blood. For an exposure concentration of 20 ppm styrene (German MAK value) a steady-state level of about 1 μg styrene-7,8-oxide/l blood was calculated.
