Abstract
The method of biological monitoring of the exposure to organic solvents by means of urinalysis is discussed. The topics include the variety of the solvents to which the method of monitoring is applicable, choice of time for urine sampling, possible correction of the results for urine density, and establishment of the biological threshold. Recent progress is reviewed in particular, in the cases of benzene, toluene, xylenes, styrene, trichloroethylene, tetrachloroethylene and 1, 1, 1trichloroethane.
