The cytotoxic effect of wastewater from the phoshoric gypsum depot on common oak (Quercus robur l.) and shallot (Allium cepa var. ascalonicum)

The effect of wastewater from a phosphoric gypsum depot on common oak, Quercus robur L., at cytogenetical level was studied. Allium-test was used as a control. The treatment of common oak seedlings with wastewater under laboratory conditions caused mitodepressive effect. Chromosome aberrations and mitotic irregularities were found. Cytogenetic analysis of common oak seedlings grown from acorns collected near the depot did not show changes in mitotic activity in comparison to control but the number of aberrations was higher than in control. In comparison to Allium-test common oak was found to be more tolerant to wastewater from the phosphoric gypsum depot.
