Renal effects of acute exposure to toluene. A controlled clinical trial.

Urinary excretion rates of beta 2-microglobulin and albumin were measured in 43 male printing trade workers and 43 age-matched male controls before and during exposure to toluene, 382 mg/m3, for 6 1/2 hours in a climate chamber. There were no significant changes in renal excretion rates of albumin and beta 2-microglobulin during toluene exposure indicating that no causal relationship exists between moderate exposure to organic solvents and renal injury.
