The effect of de-icing liquids on the chemical composition of eluate in a column experiment with sod-podzolic soil
Abstract
The influence of the discharge of spent aircraft deicing fluid (ADF), utilized in civil aviation, on the chemical composition of the eluate of sod-podzolic soil was being studied in a column experiment. It was determined that Al, Ca, Cd, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, Sr, and Zn are released into the environment together with the ADF. It is also shown that the ADF leads to changes in the indicators of the composition of lysimetric waters such as СOD, pH, Eh, electrical conductivity, and heavy metal content. As a result of the ADF discharge, several elements, including Fe and Mn, become more mobile and migrate to the liquid phase, while others are fixed in the soil, resulting in the redistribution of elements in the soil profile.
