STUDIES OF CERTAIN TRACE ELEMENTS IN INDUSTRIAL EFFLUENTS, SEDIMENTS AND THEIR EFFECT ON PLANT PHYSIOLOGYK. SIVA KUMAR K. V. SUBBAIAH, D. V. R. SAI GOPAL,Abstract Trace elements such as chromium, lead, copper, zinc and iron were detected from industrial effluents and in their sediments by atomic absorption spectrophotometer. Effect of these elements on different plant species were studied by using wet ashing method. These studies revealed that the trace lements which are present in effluents and sediments alterd the physiology of certain plant species. These trace elements showed toxic effect on different plant organs such as-leaf, stern, root, flower etc.
