PHYTOREMEDIATION OF HEAVY METALS IN MUNICIPAL WASTEWATER IRRIGATED SOILS AND THEIR GEOCHEMICAL BEHAVIOR AND SPECIATION IN MYSURU CITY, INDIA

Wastewater is a major receptacle for contaminants as it possesses an ability to bind various toxicity substances. These chemicals can exist in various forms in wastewater and growing crops different forces. It is essential to study these interactions becau se the toxicity of chemicals may strongly depend on the form in which they exist in the environment. Another thing is that crops variability in some environmental properties may change in soil and cause leaching of trace toxic elements. Metals associated w ith urban wastewater and crop species are great concern because of their direct and indirect effects on human health. The main purposes of this phytoremidiation study undertaken in the Mysuru city Municipal wastewater irrigated zones were to identify heavy metals with dangerous environmental load and to find out of their environmental impact (Cd, Cu, Fe, Ni, and Zn). The purpose of this work was to provide information on heavy metals concentration in selected crops and heavy metal speciation in crops carrie d out were shows that all metals were mainly associated with the oxidizable and residual fraction, which allows us to predict their mobility in the crop.
