IN SITU REMEDIATION OF HEAVY METAL POLLUTED SOILS WITH FLUSHING

 Koptsik G.N., Koptsik S.V., Smirnova I.E., Livantsova S.Yu.

Effectiveness of soil flushing for in-situ remediation of polluted soils was studied in the vicinity of a copper-nickel smelter in the Kola Peninsula. Water, hydrochloric and citric acids were applied in order to remove heavy metals from topsoil followed by their fixing with vermiculite placed in subsoil. Both acids were highly effective in mobilizing heavy metals, but the potential of soil acidifcation and nutrient leaching was extremely higher in HCl treatment. Citric acid can be recommended as effective and environmentally friendly agent for soil remediation. Water as a mobilizing agent was less effective. Careful management of remediation process and exact evaluation of soil and sorbent parameters seems highly desirable to determine whether chelate- or acid-enhanced remediation can be used safely without creating new problems related to ground water pollution and ecosystem disturbance.

PHYSICAL PECULIARITIES OF PHOSPHOGYPSUM AND ITS IMPACT UPON SOIL’S COVER PROPERTIES

 Murav’ev E.I.

The solubility of Belorechensk Chemical Plant’s phosphogypsum dihydrate has been studied within the laboratory conditions. Waste’s solubility increases with the addition of ammonia saltpetre to phosphogypsum. Granulometric composition of phosphogypsum differs greatly from the soil. Thus, by mixing in substrate, the part of micro- and macro-aggregates grows. This process makes aeration much better.
