Abstract
The paper reports a study of the effects of peak discharge of waste aircraft de-icing fluid (ADF) on the chemical composition of sod–podzolic soil eluate in a column experiment. It has been demonstrated that Al, Ca, Cd, Cr, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, Sr, and Zn ions are delivered into the environment together with wasted ADF. It has been shown that ADF causes changes in the composition parameters of the percolate, including the chemical oxygen demand, pH, redox potential, electrical conductivity, and heavy-metal content. The elements in the eluate are divided into four groups depending on the type of change in their concentration in the column effluent. Some elements, including Fe and Mn, become more mobile and move to the liquid phase due to the ADF input, while others become fixed in the soil, resulting in a general redistribution of elements in the soil profile.
