Description
Summary:This study examined the influence of the land-uses on the performance of the selected heavy metals using Z-score and coefficient of variation. In order to achieve the aim of this study, thirty surface pond waters were sampled across four land uses in Akoko Northeast LGA of Ondo State, Nigeria. The sampled water were assessed for four heavy metals (zinc, iron, manganese and copper) and evaluated using the Z-score and coefficient of variation. Observed heavy metals results were converted to standardized Z-scores to facilitate objective comparisons and enablement of performance among each parameter in the ponds across the land uses. The predefined water quality result variations were objectively subjected to coefficient of variation to confirm the level of parameters comparability. In conclusion, the study exhibited spatial variation in concentrations of the four heavy metals as a result of different land uses characteristic.
