Sažetak
Aluminium at 80 and 100 mg/l showed distinct toxic effects on the planarian Polycelis felina treated for 24 h in neutral and acidic media, pH 7.1 and 5.2 respectively. Aluminium in acidic media induces higher mortality, stronger morphological and behavioural changes and more extensive tissue damaage. Changes induced by aluminium in concentration used were present in the form of damaged anterior and postrior body parts, occurence of lessions on the body surface, depigmentation and disturbances in behaviour and locomotion. Changes in cyto-histological structure included decomposition of mucous layer, damages to the epidermis, degradation of tissue, occurrence of large cavities within parenchyma and an increased number of rhabdites and neoblasts within the zones of damage. Surviving planarians regenerated damaged body parts, but they were smaller and permanently lacking pigmentation.
