The Authors have studied AST and ALT enzymatic activities in the workers of two firms, the former of which (tannery) with a high and the latter (boot and shoe factory) with a low level of hepatic-toxic risk. The influence of various trouble factors such as age, sex and seniority was eliminated through appropriate statistical techniques. A significant difference was evidenced between AST and ALT levels in two firms, chiefly attributable to the quantity and quality of the substances utilized in the two technological cycles: trichloroethylene, chromium, sulphuric acid, mineral oils, ammonia, N-hexane, pentanes acetone, ciclo hexane, methanol, ethyl acetate, isopropyl acetate, toluene, methylene chloride.
