SULTANA, MUNIRA. Department of Environmental Science and Human Engineering, Saitama University, 255 Shimo-Okubo,Saitama 338-8570,Japan. - Arsenic Terrorism : Macrophytes Are Also Terrified.
An environmental health disaster is unfolding in Bangladesh.Around 70%
inhabitants are drinking arsenic contaminated water.Death,arsenic
related diseases and potential chronic arsenic suffering are
increasing day by day.4 million hectares macrophytes rich beneficial
wetland are also affected.This investigation demonstrated the effect
of exceeding concentration of arsenic on some rooted macrophytes in
relation to different arsenic level in 5 different area of
Bangladesh.Eichornia crassipes , Potamogeton crispus ,
Elodea canadensis and Nymphaea nouchali were selected
for this study.Except Eichornia crassipes , rest of the three
plants showed phytotoxic symptoms at 450µ arsenic
concentration.Arsenic toxicity resulted necrosis of leaf,die-back of
plant and retard the growth.
