Cadmium and zinc from anthropogenic sources in Lake Nakuru were investigated. High metal levels (mg/kg) in soils (Cd ≤ 16.3 and Zn ≤ 280) and Acacia xanthophloea (Cd ≤ 32 and Zn ≤ 310) were observed at polluted sites. Significant variations in metal values were evaluated using ANOVA (F test) and student's t test at p < 0.05 and metal correlations studied. High levels of metals in soils and unhealthy/dying Acacia were obtained at polluted sites. Significant positive correlation was obtained between Cd and Zn in soils and plants. Acacia sp are effective biomonitor of environmental quality in areas subjected to pollution.
