Concentration values of Pb and Zn in the leaching solution of all samples. The y-axis in this figure was cut at the concentration of 2 mg/L, to compare the residual low quantities of heavy metals in stabilized samples. As a consequence, the concentrations of Pb and Zn in the leaching solution of the MSWI fly ash result out of the scale. The corresponding pH of the solutions is also reported.
