“…Consequently, at contamination of chernozem with thallium, microbiological indices (the bacterial count and the abundance of the Azotobacter bacteria) were more sensitive, and the enzyme activity indicators (catalase, dehydrogenase) and phytotoxicity (germination of plant seeds) were more informative. Similar patterns are characteristic for most heavy metals and metalloids (Kolesnikov et al, 2000(Kolesnikov et al, , 2008(Kolesnikov et al, , 2009.…”

Thallium is a rare and highly toxic heavy metal. The scale and degree of soil contamination with thallium are increasing every year, and the associated environmental risks have been insufficiently investigated. Model laboratory experiments on the ordinary chernozem pollution with thallium oxide (III) have been carried out. It has been found that the ordinary chernozem pollution with thallium worsened its biological activity. The total bacterial count, the abundance of the Azotobacter bacteria, the activity of catalase, the activity of dehydrogenases, and the germination of radish seeds decreased. The degree of deterioration of the chernozem biological activity depends on the thallium concentrations in soil and the period from the moment of contamination. In the vast majority of cases there is a direct correlation between the thallium content in the soil and the level of soil biological activity reduction. The greatest negative impact of thallium pollution on chernozem biological activity has manifested itself 30 days after contamination. On the 90th day, there was a pronounced tendency to restore the chernozem biological activity. However, the chernozem biological activity did not restore to the initial uncontaminated soil values. At contamination of chernozem with thallium, microbiological indices (the bacterial count and the abundance of the Azotobacter bacteria) were more sensitive, and the enzyme activity indicators (catalase, dehydrogenase) and phytotoxicity (germination of plant seeds) were more informative. All used indicators of biological activity demonstrated high sensitivity to soil contamination with thallium and high correlation coefficients with the thallium content in the soil. Therefore, these biological indicators should be used for monitoring, diagnosis, indication and regulation of soil contamination with thallium.

“…Chrome, regardless of the soil type always has a stronger negative impact than copper, lead and nickel. But the last three items, showing in general a similar degree of toxicity, on different soils occupy different places in a series of toxicity relative to each other (Kolesnikov et al, 2009;2011;Kolesnikov et al, 2010a;2013a;2014a).…”

“…According to the degree of resistance to chemical contamination brown soils occupy the following position in the South Russian soils (soils are ranked according to their resistance reduction): Ordinary chernozem > typical chernozem, southern chernozem > leached fusion chernozem, dark brown, chestnut soil > brown carbonate, light brown, mountain-meadow (subalpine), gray mountain forest > brown semidesert, brown mountain-forest, solonetses, salt marshes > sandy soils (Kolesnikov et al, 2009;2011;Kolesnikov et al, 2010b;2013b;2014b).…”

Contamination of brown calcareous soils with Cr, Cu, Ni, Pb and oil leads to deterioration of their biological properties. There is a reduction in activity of catalase and dehydrogenase, an abundance of Azotobacter genus bacteria, cellulolytic activity and the length of radish roots. As a rule, there is a direct relationship between the content of contaminant in the soil and degree of deterioration of biological properties of the soil. According to the degree of negative impact on the biological properties of brown soil heavy metals form the following series: Cr > Cu > = Pb > = Ni. The pattern that chromium is more toxic and copper, lead and nickel have less and similar to each other degree of toxicity was established earlier in research conducted by the same method, with other soils in southern Russia. According to the degree of resistance brown soils are close to chestnut soils, they are less stable than chernozems and more stable than brown semi desert soils. Regional standards of Cr, Cu, Ni, Pb and oil content in brown soils of Ciscaucasia dry subtropics Ciscaucasia are proposed.

The use of silver in various spheres of life and production leads to an increase in environmental pollution, including soil. At the same time, the environmental consequences of silver pollution of soils have been studied to a much lesser extent than those of other heavy metals. The aim of this study is to estimate silver ecotoxicity using the soil state biological indicators. We studied soils that are significantly different in resistance to heavy metal pollution: ordinary chernozem (Haplic Chernozems, Loamic), sierosands (Haplic Arenosols, Eutric), and brown forest acidic soil (Haplic Cambisols, Eutric). Contamination was simulated in the laboratory. Silver was introduced into the soil in the form of nitrate in doses of 1, 10, and 100 mg/kg. Changes in biological parameters were assessed 10, 30, and 90 days after contamination. Silver pollution of soils in most cases leads to deterioration of their biological properties: the total number of bacteria, the abundance of bacteria of the genus Azotobacter, the activity of enzymes (catalase and dehydrogenases), and the phytotoxicity indicators decrease. The degree of reduction in biological properties depends on the silver concentration in the soil and the period from the contamination moment. In most cases, there is a direct relationship between the silver concentration and the degree of deterioration of the studied soil properties. The silver toxic effect was most pronounced on the 30th day after contamination. In terms of their resistance to silver pollution, the studied soils are in the following order: ordinary chernozem > sierosands ≥ brown forest soil. The light granulometric composition of sierosands and the acidic reaction of the environment of brown forest soils, as well as the low content of organic matter, contribute to high mobility and, consequently, high ecotoxicity of silver in these soils. The regional maximum permissible concentration (rMPC) of silver in ordinary chernozem (Haplic Chernozems, Loamic) is 4.4 mg/kg, in sierosands (Haplic Arenosols, Eutric) 0.9 mg/kg, and in brown forest soils (Haplic Cambisols, Eutric) 0.8 mg/kg.
