Sažetak

This paper describes the application of static headspace gas chromatography in determining benzene in urine. The method was analytically validated for sensitivity (DL=42 ng/l), repeatability (RSD=3% and 4%), and accuracy (71%), and was applied in measuring urine benzene in nonsmokers (N=14) and smokers (N=18). All urine samples had measurable benzene concentrations. The method proved sensitive enough to establish a significant statistical difference (P<0.000614) in urine benzene concentrations between smokers (mean=760; range =181–1869 ng/l) and nonsmokers (mean=214; range=61–515 ng/l).
