This report describes the preparation of a batch of 1100 filters loaded with welding dust, containing approximately 100 ug Cr(VI) per mg dust, which is as normally encountered on the personal filter monitors of stainless steel welders. The homogeneity and stability studies and the analytical work performed for the certification of the contents of Cr(VI) and the total soluble Cr content are also described. The report contains all the results and gives the methods used to certify the mass fraction of Cr(VI) and total leachable Cr. A brief description of the preliminary feasibility study is also given.
