An extraction procedure has been developed for the determination of benzene by gas chromatography in tissues following inhalation. Results are reproducible using very small quanities of sample (0.05 g for tissue and 0.02 ml for blood). The procedure has been applied to the analysis of blood and tissue of A.K.R. mice following a single exposure to levels similar to those that may be found in industrial hygiene atmospheres.
