Activity of xanthine oxidase, levels of lipid peroxidation and ascorbic acid were studied in African land snail (Achatina marginatus) from two sites with different pollution potentials. Lipid peroxidation was significantly higher in the snails from the polluted site compared to the value obtained from the same species from the control site. Similarly, the activity of xanthine oxidase in the sna...
