Characterization and cytogenotoxicity of water samples from Challawa River in Kano, Northwest Nigeria
This study assessed the cytogenotoxicity of water samples obtained at the discharge site and about 1.5 km downstream of the discharge site of a textile factory along Challawa River, Kano, Nigeria. After physicochemical and microbial characterizations, water samples were used to grow 20 Allium cepa...

| description | This study assessed the cytogenotoxicity of water samples obtained at the discharge site and about 1.5 km downstream
of the discharge site of a textile factory along Challawa River, Kano, Nigeria. After physicochemical and microbial
characterizations, water samples were used to grow 20 Allium cepa bulbs divided into two equal groups for 72 hrs. A control
group was similarly conducted, but was grown over deionized water. Root-tips of the bulbs were then examined for chromosomal
aberrations. Physicochemical analysis showed that the levels of Ca, Cd, Cr, Pb, DO, BOD, COD, turbidity, and nitrate in both
water samples were not within WHO standards. Only the bacterial loads of samples from 1.5 km distance were abnormal in the
microbial analysis. A significant (p<0.05) reduction in mitotic index and bi-nucleated cells, sticky and vagrant chromosomes
were observed in the treated bulbs. These findings showed that the water samples could be toxic. |
