Assessment of Cytotoxicity and Genotoxicity Potential of Effluents from Bahir Dar Tannery Using Allium cepa

Figure 2

Root growth (%) of A. cepa at different concentrations of tannery effluent with 48-hour exposure. The root growth of tannery effluent concentration was significantly different from the control as determined by a simple regression test (P < 0.05).
