Abstract: A sample of suspended particulate matter in the indoor air of a steel welding workshop located in an industrial area of Raipur was collected and analyzed for toxic metals (Cu, Co, Cr, Cd, Fe, Pb, Mn, Ni, Zn and Hg). A sample of the welding electrodes was also analyzed. The occurrences of the heavy metals in the suspended particulate matter were found in the order: Fe> Mn> Cr> Zn> Ni> Pb> Cu> Co> Hg> Cd. The same order was found in the electrode material, which suggested the transfer of toxic metals from the welding electrodes to the particulate matter generated in the workplace during the arc welding process.
