In the present study, the determination of arsenic, lead, cadmium, chromium, cobalt, copper, nickel, mercury and zinc in various cloth samples produced in Kayseri-Turkey was performed after extraction with artificial sweat solution and decomposition with nitric acid. TXRF is shown to be suitable for the determination of 7 trace elements, down to the 0.001 (cobalt) to 0.004 (copper) mg/kg level in textile extract except for mercury and cadmium. The extractable part of the toxic metals by artificial sweat solution is relatively low. In a few extracts the concentration values of Pb and Ni have exceeded their critical values of 0.2 mg/kg for lead and 1.0 mg/kg for nickel given by Öko-Tex and determined for babys cloths. In addition, it was observed that the element pattern of textile samples resembled ‘finger print type’, TXRF-spectra. This technique can also be used for the identification of textile sample in forensic investigation.
