Search for: [Abstract = "Concentrations of TOC varied from trace amounts to 22,65% dry mass dependently on geology. Soils under research contained high amounts of iron and were poor in calcium. Aluminium concentrations were imperceptibly lower than iron ones and varied from 0,27 to 7,45% dry mass. The following conclusions were formulated\: chemical composition of soils stayed under influence of interactions with AMD, the content of iron and calcium may be the result of secondary minerals precipitation form AMD, lack of calcium created conditions favourable water and soil acidification."]
