    Heavy Metals Speciation, Mobility, and Bioavailability in Constructed Wetland Sediment Treating Polluted River Water: Implication for Environmental Safety
    Author(s): Deshu Mamo Mekuria*

    The presence of toxic heavy metals in sediments beyond allowable limits are often posing a serious threat to local environment. Constructed wetland sediments contamined with heavy metals can affect sediment-dewlling biota such as benthic organisms, wetland plants, aquatic life including amphibian and reptiles. The objective of this study was to investigate heavy metals, mobility and bioavailability, level of environmental risks, and it implication for environmental safety. The study was conducted using the horizontal subsurface flow (HSSF) constructed wetland (CW) sediments designed for treating polluted Little Akaki River water. The sediment samples were collected from the CW and heavy metals speciation determined following the European Community Bureau References (BCR) sequential extraction procedures. The results showed that the highest percentage of metal fractions: Zn = 71.67%, C.. Read More»
