| Abstract: | Various aquatic plant species are known to accumulate heavy metals through the process of bioaccumulation. World’s most troublesome
aquatic weed water hyacinth (Eichhornia crassipes) has been studied for its tendency to bio-accumulate and bio-magnify the heavy metal contaminants present in water bodies.
The chemical investigation of plant parts has shown that it accumulates heavy metals like lead (Pb), chromium (Cr), zinc (Zn),
manganese (Mn) and copper (Cu) to a large extent. Of all the heavy metals studied Pb, Zn and Mn tend to show greater affinity
towards bioaccumulation. The higher concentration of metal in the aquatic weed signifies the biomagnification that lead to
filtration of metallic ions from polluted water. The concept that E. crassipes can be used as a natural aquatic treatment system in the uptake of heavy metals is explored. |
