"High risk of potential contamination is associated with the determination of concentrations of trace elements in plant root material. Therefore, the cleaning procedure is extremely important in the preparation of plant root samples for the quantification of different trace elements in the roots. In this study, nine different cleaning solutions were tested to determine the most efficient one. The results of this investigation suggest that there is no universal washing procedure for plant root samples. However, it appears that there are better suited, as well as inadequate, procedures. Washing the roots with (0.01M) HCl have shown some degree of leaching. Washing solutions of (1%) detergent, (1M) MgCl₂ and (0.01M) EDTA appear to yield an intensive removal of surface contaminants from the roots and negligible leaching of trace elements in the root tissue"--Abstract.
