Temporal and Spatial Variations on Heavy Metals Concentration in River Mojo, Oromia State, East Ethiopia
Abstract: This study was aimed to reveal the temporal and spatial concentration variations of trace heavy metals in extreme wet rainy season, semi wet and semi - dry period (autumn), and extreme dry season (winter). The experimental results of this study unveiled that the level of As increases from the wet to dry periods of the year showing the dilution effects. Except for a single result, all analyzed results of As are above WHO Drinking Water Guidelines (DWG) (0.01mg/l). Cd pollution load is observed to be low in all study locations and sampling periods (mean value = 0.12 0.075mg/l). All the experimental results of Hg are significantly (p = 0.043, p
