Lead is considered a major toxic metal that runs off from urban areas to wetlands in
Sri Lanka. Researchers at
University of Kelaniya found that rooted aquatic plants such as Habarala species can be used to remove these toxic chemicals as these plants have ability to absorb and store those chemicals.
These findings, which were based on a study conducted at Iriyawetiya freshwater wetland situated in the vicinity of Kiribathgoda urban area, will be presented at International Forestry and Environment Symposium at 30th November by K.G.S. Nirbadha, Dr.M.D. Amarasinghe and Dr.J.A. Liyanage.
