“…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.

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.

“…The same researchers noted a decreased activity of dehydrogenase under a dose of fluorine as low as 100 mgF•kg -1 of soil, while arylsulphatase was even more sensitive -responding negatively to just 20 mgF•kg -1 of soil. Kolesnikov et al [26], who investigated the effect of soil contamination with fluorine, boron, selenium, and arsenic demonstrated an inhibited activity of dehydrogenase, invertase, and catalase in soil. Garcia-Gil et al [27] also confirm that the enzymatic activity of soil -including such soil enzymes as dehydrogenase, phosphatase and urease -decreases in response to increasing soil contamination by fluorine.…”

The objective of this research has been to determine the impact of soil contamination with fluorine, including the concomitant application of substances neutralizing this pollution, on counts of actinomyces, fungi, and copiotrophic bacteria, and on the activity of acid phosphatase, alkaline phosphatase, grease, and dehydrogenase. The research was based on two pot experiments, both conducted in 2009 in a greenhouse at the University of Warmia and Mazury in Olsztyn, Poland. One experiment involved winter oilseed rape, while the other was performed on maize followed by yellow lupine. The following factors were included in both experiments: I) increasing doses of fluorine in the form of potassium fluoride (0, 100, 200, 300 mgF•kg-1 of soil) II) substances neutralizing soil pollution with fluorine: lime, in a dose corresponding to 1 Hh of soil, charcoal, and loam-both in amounts equal to 3% of the soil mass per pot. The biological activity of soil was assayed after harvesting winter oilseed rape (BBCH 69) and yellow lupine (BBCH 69). It has been demonstrated that low doses of fluorine (from 100 to 200 mgF•kg-1 of soil) had a positive influence on counts of the analyzed microorganisms and on the activity of the examined soil enzymes. Under the influence of such low amounts of fluorine, the number of actinomyces and the activity of urease increased in soil tested after the harvest of winter rape and yellow lupine, the latter being a catch crop sown after maize. The neutralizing substances had a much better effect on counts of the analyzed microorganisms than on the activity of soil enzymes. The counts of actinomyces and copitrophic bacteria were positively affected by all the substances added to soil, as compared to the control treatments. With respect to fungi, these microorganisms responded positively only to the application of charcoal and loam to soil cropped with yellow lupine. In general, the tested substances had a beneficial influence on the activity of acid phosphatase and urease. As regards the activity of alkaline phosphatase, it was adversely affected by the neutralizing substances. The residual effect of fluorine on counts of the analyzed microorganisms and activity of the soil enzymes was milder in the soil sampled after the harvest of yellow lupine, which seems to indicate that fluorine loses its toxic properties with time.
