<abstract xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">Current research indicates that lipid peroxidation could have a role in aluminium toxicity. The aim of this study was to asses lipid peroxidation and antioxidative enzyme activity in erythrocytes of workers occupationally exposed to aluminium.

The control group (C group) consisted of 75 subjects employed in lime production who had not been occupationally exposed to aluminium or any known toxic substance.Erythrocyte aluminium concentrations were significantly higher in the exposed group than controls [Al group (8.41±3.66) μg L-1, C group (5.60±0.86) μg L-1, p&lt;0.001].
