Abstract:
The designation of sedimentation dust and its contents of trace elements is submitted to an critical reflection of errors. Essential falsifications of the analytic results can be produced by the use of dust-laying deionized or distilled water, the material of vessels, the anti-freeze agent, the different diameters of vessels apertures and the entry of foreign bodies. The possibilities of making less errors in analysis are being discussed and the feigned surface pollution is calculated.
