“…A similar pattern was obtained in studies conducted earlier with other soils of the South of Russia: ordinary chernozem, southern chernozem, typical chernozem, leached chernozem, compact chernozem, brown and gray forest chernozems, sod carbonate chernozem, alpine humus chernozem, and chestnut chernozem [7][8][9][10][11] .…”

In studies on chemical contamination of soils, little attention is paid to disguised solonchaks. This is due to the low significance of disguised solonchaks for agriculture and the lack of significant pockets of chemical contamination in the areas of their extension. At the same time, these soils are widely extended in the coastal landscapes and perform important ecological functions. They are involved in the maintenance of biodiversity and the sustainable functioning of natural ecosystems. As shown by the current study, the contamination by Cr, Ni, Cu, Pb and oil leads to a deterioration of the biological properties of the hydromorphic estuary carbonate solonchak. This means decrease in the total number of bacteria, the activity of catalase and dehydrogenase, cellulolytic ability, abundance of the Azotobacter genus bacteria, as well as worsening indicators of radish seeds germination and initial growth. In terms of toxicity to the biological properties of the investigated marsh solonchak the studied elements form the following sequence: Cr>Cu>Ni>Pb. High toxicity of Cr compared to Pb, Ni and Cu in marsh solonchak is explained by weak alkaline reaction, in which CrO 3 is transformed into highly toxic chromate.

This paper provides an assessment of the resistance of Taman chernozems to contamination with heavy metals (Cr, Cu, Ni, Pb) and oil by biological parameters. As a rule, upon contamination of the Taman chernozems, a significant reduction was observed in the total bacterial count, activity of catalase and dehydrogenase, cellulolytic activity, abundance of the Azotobacter genus bacteria and in the radish germination intensity. The extent of the deterioration in biological properties was determined by two factors: the chemical nature of the metal and its amount in the soil. As a rule, a direct relationship was observed between the concentration of the pollutant and the degree of deterioration of the soil properties in this study. The metals studied had shown different ecotoxicity with respect to the chernozems of Taman: Cr > Cu ≥ Ni = Pb Regional norms for the maximum allowable content of Cr, Cu, Ni, Pb, and oil in the Taman southern chernozems based on a disturbance of the ecological functions of soils were proposed.

“…Процесс добычи и транспортировки нефти и нефтепродуктов в республике еще далек от совершенства, аварийные ситуации, изношенность обору-дования, халатность работников -все это приводит к попаданию углеводородов в окружающую среду. Попав в почву, нефть в первую очередь влияет на ее биологические свойства, нарушается активность почвенных ферментов [1][2][3], также происходит резкое изменение физико-химического состояния почв, что негативно сказывается на росте и развитии растений, произрастающих на этих почвах.…”
