Chromium and Cobalt Concentrations in Textile Products and the Amounts Eluted into Artificial Sweat

In this study, elements present in 78 textile products (106 samples) made of nylon, wool, and silk were analyzed by X-ray fluorescence. Twenty elements were detected in one or more samples, and Cr and Co were detected in 66 and 40 samples, respectively. Elution tests using seven samples which contained Cr and Co at high concentrations were performed using artificial sweat.
