Abstract– Hexavalent chromium compounds are genotoxic carcinogens. Chronic inhalation of hexavalent chromium compounds increases the risk of lung cancer. Chromium salt also shows inhibitory effect on sporulation of Blue Green Algae. In the present study effect of Chromium salt was observed on sporulation of Anabaena macrospora. In a short period (8th day), the lower concentration of Chromium salt does not affect akinete formation in Anabaena macrospora but the higher concentration inhibit spore formation. After a period of 16th day even the lowest concentration of Chromium salt inhibit akinete formation in Anabaena macrospora.
Key words: Hexavalent chromium, Carcinogens, Akinetes
