| contents | <div> <table> <tbody> <tr> <td style="padding: 0in;"> <p><span>Ten heavy metals (As, Bo, Cd, Cr, Cu, Fe, Mn, Ni, Pb, Zn) were assessed in Ulasi river, Okija. Three sample stations that include; station A. Ubahuabuba, station B. below bridge along Okija-Nnewi Road, station C. Onitsha – Owerri road were analysed. The result was obtained using ANOVA statistical analysis and there was significant difference of 0.05%. The results obtained also revealed that the mean concentrations of the metals ranged from Arsenic 0.012 to 0.19mg/l, Bo 0.057 to 00.77mg/l, Cadmium 0.008 to 0.035mg/l, Chromium 0.028 to 0.039mg/l, Lead 0.017 to 0.029mg/l, Manganese 0.046 to 0.070, Fe 0.056 to 0.076mg/l , Cu 0.037 to 0.068mg/l , Zn 0.050 to 0.112mg/l and Nickel 0.039 to 0.076mg/l with Arsenic , Cadmium , Lead , Nickel were in excess when compared with the WHO (2017) guidelines for drinking water ,whereas the other metals analysed were within the recommended limit . The Ulasi water is therefore unfit for drinking except after adequate treatment.</span></p> <p><strong><span> </span></strong></p> </td> </tr> </tbody> </table> </div> |
