dc.description.abstractHeavy metals have high significance among the inorganic contaminants of surface water (e.g. pond and stream) due to their non-degradable nature in heighten injurious biological affect. For this reason, there, 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 ponds water were sampled across four land uses in Akoko Northeast LGA of Ondo State, Nigeria. The sampled water were assessed for four heavy metals and evaluated using the z-score and coefficient of variation. The heavy metals are zinc (Zn), iron (Fe), manganese (Mn) and copper (Cu) while the land uses comprise of built-up areas, cultivated lands, vegetation and crop plantation. Observed heavy metals results were converted to standardized z-score (z) to facilitate objective comparisons and enablement of performance among each parameter in the ponds across the land uses The predefined water quality result variation were objectively subjected to coefficient of variation (CV) to confirm the level of parameters comparability. Thus, the z-score results of heavy metals identified strong remarkable spatial dependency when p>0.01 or weak remarkable spatial dependency when p<0.01 while performance denote homogeneous when CV<50% heterogeneous when CV>50%. In conclusion the study exhibited spatial variation in concentration of the four heavy metals as a result of different land uses characteristicsen_US
