Study of Toxic Elements in River Water and Wetland Using Water Hyacinth ( as Pollution Monitor.

The concentration of toxic elements present in surface water of Sutlej River and Harike wetland besides , commonly known as water hyacinth, is estimated employing inductively coupled plasma mass spectrometry (ICP-MS). Toxic elements such as cadmium (Cd), chromium (Cr), copper (Cu), manganese (Mn), nickel (Ni), lead (Pb), uranium (U), and zinc (Zn) are identified in the river as well as in Harike wetland catchment. Accumulation of elements in different parts of the water hyacinth plant is observed with the roots exhibiting maximum affinity followed by stem and then leaves.
