Item Open Access Genotoxicity of hairdressing salon effluent using allium cepa(U. P., 2020) Okereke, J. N.; Dike, Ijere. N.; Ukaoma, A. A.; Ezejiofor, T. I. N.Genotoxicity of hairdressing salon effluent using Allium cepa was carried out using different concentrations of 12.5%, 25%, 50% and 100% of hairdressing salon effluent obtain from different outlets. The presence and concentrations of some heavy metals such as lead, Mercury, Zinc, Cadmium and Arsenic in the effluent were determined using Atomic Absorption Spectrophotometer (AAS). Chromosomal aberration assays were used to determine the mitotic index and chromosome aberration rate. There was an increase in the mitotic inhibition as the concentration increased whereas there was a decrease in the mitotic index, indicative of an inverse relationship shared by the two properties. The effluent induced chromosomal aberrations in the meristematic cells of the A. cepa root tip, and laggards were the most frequently recorded aberrations induced. Morphological abnormalities were also recorded in the roots of the Allium cepa. The genotoxic effects of hairdressing salon effluent on Allium cepa indicates that it contains toxic substances which may constitute environmental risks particularly on soils and plant crops planted near hairdressing salon facilities.
