Awba Dam water contains constituents that induced genetic and systemic damage in Pb, Cd, Ni and Fe in the water samples contributed to the Observed in sections of liver and kidney. Histopathological alterations, including degeneration, congestions and inflammations were At theĮxposure periods in mice, there was significant (p<0.05) increase in frequencies of abnormal sperm cells,Īlterations in haematological parameters and significant (p<0.05) increase in the levels of alanineĪminotransferase and aspartate aminotransferase when compared with the corresponding negativeĬontrols. (p<0.05) mitotic inhibition and induction of different types of chromosome aberra tions in A. Tap water from underground source was used as negative control. cepa root growth inhibition and chromosomeĪberration test, and was administered as drinking water to groups of male Swiss albino mice for 35, 70Īnd 105 days. Bi-monthly composite water samples were collected from the Dam from Systemic toxicity in mice using alterations in haematological, serum hepatic biochemical and In this study, we investigated the cytotoxic and genotoxic effects ofĪwba Dam water using the Allium cepa and murine sperm morphology assays. Residences, research laboratories and surrounding farmlands. It receives both point and non-point sources of untreated sewage and wastewaters from student and staff In view of these results, the practice of discharging untreated canteen wastewater into drainage canals may not be environmentally sustainable.Īwba Dam reservoir is an important source of domestic water supply in the University of Ibadan, Nigeria. The differences in total chromosomal aberrations across wastewater concentrations were not statistically significant (P > 0.05). No chromosomal aberration was observed in onion roots exposed to water (control). cepa exposed to different concentrations of canteen wastewater were vagrant, sticky, and bridged chromosomes. The major chromosomal aberrations observed in A. The wastewater was highly mitodepressive, with mitotic inhibition generally increasing with rising concentrations. cepa at 0.1%, 1%, 10%, 25%, 50%, and 100% concentrations but promoted root growth at 2% and 5% concentrations. The wastewater inhibited root growth in A. The chloride concentration of the wastewater (7873.60 mg/l) was much higher than the recommended limit of 250 mg/l. Results showed that the wastewater had total suspended solids, total dissolved solids, and total hardness concentrations of 120.70 mg/l, 554.50 mg/l, and 500.00 mg/l, respectively. In this study, the wastewater generated by a canteen complex was screened for physicochemical properties and genotoxic potential using standard procedures and Allium cepa chromosome assay. Canteens generate high volumes of wastewater that should constantly be subjected to physicochemical and genotoxicity screening.
