ABSTRACT
Environmental pollution/contamination poses serious threat to humans and other organisms. Pollutants and anthropogenic activity can damage the environment. The aim of this study was to investigate changes in antioxidant status of the head of Xenopus laevis from UNIBEN Capitol, Uwelu and Okhuo areas in Benin metropolis. The heads of collected X. laevis were excised, homogenized and used for biochemical analyses. In this study, the activities of catalase and SOD in X. laevis obtained from Okhuo were significantly lower than those of the same animal collected from UNIBEN capitol and Uwelu (p < 0.05). However, X.laevis obtained from Okhuo had the highest concentration of glucose, when compared to those of UNIBEN capitol and Uwelu (p < 0.05). There were no significant differences in the activities of SOD and catalaseaswell as glucose concentration of the animals obtained from Capitol and Uwelu (p>0.05). The results of physicochemical analysis showed that Okhuo and Uwelu water were slightly acidic compared to Capitol (p < 0.05). Uwelu site had the highest TDS and alkalinity followed by Capitol. While Capitol had the highest DO, there were no significant differences in BOD among the three sites (p<0.05). Water from Okhuo had the highest COD, Fe, Zn, and Cu when compared to the other two sites (p < 0.05) (Table 3.2).
