Spatial Trends of Physico-Chemical Characteristics and Metal Levels in Ecosystems of the Mini-Whuo Stream, Eliozu, Rivers State.
Resumen
Spatial trends of physicochemical characteristics and levels of heavy metals (Pb, Cr, Zn, and Mn) were measured in surface water, sediment, invertebrates, and macrophytes of Mini-Whuo Stream, Eliozu. Metal concentrations were determined using aqua-regia digestion followed by Atomic Absorption Spectrophotometry (AAS). The study aimed to assess the possible impact of anthropogenic activities on the water body. Specific physicochemical parameters such as organic matter, pH, and conductivity—which influence metal interactions and dynamics within the sediment matrix—were also measured. The mean levels of these physicochemical characteristics in both surface water and sediments fell within permissible limits for potable water, indicating the freshwater nature of the water body. However, metal levels varied widely across different ecosystem components. High metal concentrations recorded in the sediments suggest significant impact from anthropogenic inputs into the water body.
