In this article, we have presented a number of modeling experiments to investigate the chemical pollution of brown calcareous soil. It assesses the stability of brown calcareous soil of a nature reserve called Utrish to contamination with heavy metals in biological parameters. Pollution of brown calcareous soil with Cr, Cu, Ni, Pb and oil causes a significant reduction in biological parameters. The degree of reduction depends on the nature of the contaminant and its concentration in the soil. The study showed that the indicators used in the biological condition of the soil, could be recommended for use for diagnosis, monitoring, and regulation of chemical pollution of brown soil. According to the degree of resistance to chemical contamination, the brown soils of Russia form the following series: typical brown - brown carbonate - brown leached
The article presents the results of laboratory
modeling of gleyisation and its effect on the
biological properties of soils with stagnant regime in
ordinary black soils. Gleyisation is a complex
biochemical process that occurs under oxygen
reduction conditions. Anaerobic microorganisms, the
presence of organic substances, and the constant or
prolonged waterlogging of individual horizons or the
entire soil profile promote gleyisation. Model
experiments revealed that gleyisation increase the
total number of bacteria and suppresses number of
actinomycetes, micromycetes and growth of fungal
mycelium. Gleyisation decreases the activity of
oxidoreductases and increases the hydrolases
activity. In addition, the second content of humus
slightly increases and active acidity (pH) changes to
neutral. Accumulation of large amounts of iron oxide
(II) in soil is revealed
This article presents an assessment of the stability of the black soil of the Crimea to contamination with heavy metals (Pb, Cu, Cr, Ni) and oil using biological indicators
The essential part of a soil cover of the Republic of Adygea is occupied by gray forest soils. Thus they still remain a little studied, including concerning their resistance to chemical pollution. Contamination of gray forest soils of Adygea with Zn, Cd, Mo, Se causes deterioration of their biological properties. In most cases, the degree of reduction of the values of biological indicators is directly dependent on the concentration of pollutant in the soil. According to the degree of toxicity to the biological properties of the investigated elements form the following sequence: Se > Zn > = Cd > Mo. Biological parameters investigated in research (activity of catalase and dehydrogenase, cellulolytic ability, abundance of bacteria of the genus Azotobacter, radish root length) may be used for purposes of monitoring, diagnosis and regulation of chemical pollution of gray forest soils Zn, Cd, Mo, Se
Rendzina soils are very widespread in the Caucasus. Because of their ecological and genetic characteristics Rendzina has significant buffering capacity to chemical pollution. The object of investigation was calcareous leached soil. Location selection - Azishskaya ridge on the border of the Republic of Adygea and the Krasnodar region. As pollutants, we have selected Zn, Cd, Mo, Se, since soil contamination with these elements in the south of Russia is not uncommon. Contamination of zinc, cadmium, molybdenum and selenium causes deterioration in the biological properties of calcareous soils of the Western Caucasus. We have investigated the toxicity of the elements formed following series due to their influence on Rendzina soils: Zn> Se> Cd> = Mo. The study attempted to analyze the entire range of concentrations of the examined elements in the soil, currently occurring in nature. In most cases, all the investigated substances registered direct correlation between the concentration of the pollutant in the soil and the degree of reduction of biological indicators. The activity of catalase and dehydrogenase cellulolytic ability, plenty of bacteria of the genus Azotobacter, length of roots of radish can be used to monitor, diagnose and regulation of chemical pollution of soil Zn, Cd, Mo, Se
The article gives an assessment of resistance of the brown typical soil of the Utrish national reserve to pollution with heavy metals (Cr, Cu, Ni, Pb) and oil on biological indicators
Negative impact of oil on biological properties of soils right after pollution is shown in the article. Eventually, there is their restoration. However, even in some years after pollution, the biological properties of soils aren't restored completely
We studied the effects of heavy metal pollution on
soil phytotoxicity cities of the Rostov region. The
research objects were the soils of urbolandscape
towns: Taganrog, Novocherkassk, Gukovo, Shakhty,
Azov. The study of the soil pollution with heavy
metals was recorded in Gukovo, Shakhty, Taganrog.
The degree of pollution of the studied cities form the
following row: Gukovo > Shakhty > Taganrog >
basics > Novocherkassk. The research was carried
out in 2011-2015 at the Department of ecology and
environmental Sciences of southern Federal
University. In most cases, there was a direct
correlation between pollutant concentration and the
degree of deterioration of the studied soil properties.
Used biological indicators are informative for
monitoring of urban soils polluted with heavy metal.
The degree of informativity of biological indicators
form the following row: root length > germination
>length of shoots. The results of the study can be
used for monitoring and diagnosing the condition of
contaminated soils, in the assessment of
environmental impact, risk assessment of natural and
synthetic disasters, the development of regional
standards on the content of heavy metals in soil and
in other environmental and industrial activities
The article considers the enzymatic activity and some other ecological and biological properties of zonal soils of the Crimea (cambisol, Chromic cambisol, different subtypes of chernozems). We have revealed significant differences in catalase, dehydrogenase, polyphenol oxidase, peroxidase,
invertase for soils of the Crimea, which can not be explained only by the content of soil organic matter. Despite the low humus content of the soil, some have a high level of some enzymes. The level of enzyme activity depends on the reaction medium, the content of carbonate and other soil properties. We have also revealed that the agricultural use of brown
soils under vineyards leads to a significant change in their properties and enzymatic activity
In the article, we have studied the effect of lead contamination, an alternating magnetic field, their combination on such groups of soil microorganisms, as ammonifying, amylolytic, nitrogen-fixing bacteria, and micromycetes. The pollution had a significant and different effect on the number of soil microorganisms. The nature and extent of this effect varied depending on the level of impact of each factor, and they were not linear
