A comparative analysis is performed of the variations in one of the resource-saving indicators, namely, the concentration of metal ions (Cr, Cu, Ni, Zn, Sn, Cd, Pb, and Fe) in the compositions of solutions proposed and used in different years for electroplating. A quantitative concentration criterion is deter-mined for classifying the compositions of solutions used for metal electroplating into resource-saving (c a parts per thousand currency sign 0.71 mol/L) and resource-intensive (c a parts per thousand yen 0.96 mol/L) compositions. In addition to scientific interest, this material can be useful for developing studies aimed at reducing the negative environmental impact of electroplating shops or sections.
