Trace elemental analysis of asbestos with an x-ray fluorescence technique

We have used an X-ray fluorescence spectroscopic technique to quantify the trace elements present in Indian asbestos samples. Elements such as Cr, Mn, Fe, Ni, Cu, Zn and Ba were commonly found in all the asbestos varieties. The differences in the trace element content of Indian samples as compared to other global samples could be attributed to the different geochemical processes involved in the formation of ores at different places. The importance of trace metals has been briefly discussed in relation to their likely adverse biological effects.
