REAL-TIME ON-LINE MONITORING OF TRACE ELEMENTS IN DIFFERENT MEDIA USING LASER INDUCED BREAKDOWN SPECROSCOPY. Akshaya Kumar and Prakash C. Sharma, Department of Physics, College of Engineering, Architecture and Physical Sciences, Tuskegee University, Tuskegee, AL 36088. It is shown that LIBS is a sensitive technique that can detect the concentration of different elements in water, soil and air in parts per million or billion scale would of great use to protect the lives from the disaster. LIBS technique has been used to monitor the concentration the concentration of trace elements like, Cadmium, Mercury and other toxic elements in soil, water and air. In addition the application of LIBS in biological sciences including the detection of cancer will be presented. A clear distinction between the LIBS spectra of normal and malignant tissue has been observed. The intensity of various elements, which is related to the concentration of trace elements in normal and malignant tissue, were significantly different. A significant differences in the relative concentration of Ca, Al, Fe, Cu, Na, K, Fe and Mg in normal and malignant tissue has been observed.
