Hepatotoxic effects of solvent exposure around permissible limits and alcohol consumption in printers over a 4-year period.
Two field studies were carried out in 1987 and 1991 in order to evaluate the effect of chronic exposure to solvent mixture on liver enzyme patterns. The results in 33 workers who participated in both studies and had complete sets of data are presented. The magnitude of chemical workload was assessed by means of ambient air monitoring and biomonitoring of solvent concentrations. Alanine aminotransferase, aspartate aminotransferase and gamma-glutamyl transpeptidase were used as markers for possible biological effects. No dose-response relationship was found between exposure to complex solvent mixtures in ambient air, reaching and sometimes even exceeding the threshold limit values for mixtures, and liver enzyme activities. Self-reported alcohol intake was the only factor identified as statistically related to increased liver enzyme activity.
