The influence of oil pollution and concomitant salinization of chernozem typical in a field experiment has been studied. It is shown that the oil intake of 2 and 3 g·kg-1 with or without sodium chloride 1 g·kg-1 does not have a
negative effect. It was found that under the influence of salinization, the content of mobile forms of heavy metals
increases by an average of 1.5 times. The analysis of the content of heavy metals in crops cultivated on the territory
of the Republic of Bashkiria (Pisum sativum L., Triticum aestivum L.) aft er contamination with oil and sodium chloride was carried out both individually and jointly in a field experiment. The content of mobile forms of heavy metals in the soil under the infl uenceKeywords: rationing of oil pollution; heavy metals migration; agricultural soils pollution; chernozem salinization

The effect of de-icing liquids on the chemical composition of eluate in a column experiment with sod-podzolic soilMoscow University Bulletin. Series 17. Soil science. 2024. 2. p.26-36read more474

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.
