“…For example, an increase in urease activity compared to the control was noted for Zn at the composting for 30 days, as well as a decrease by 20% after 60 days of composting. According to some authors, low HM concentrations can activate the enzyme activity (Belyaeva, 2002;Grigoryan, 1990;Minnikova et al, 2017). Under Cd contamination, the activity of urease decreased by 17% after 30 days and returned to the control level (23%) after 60 days.…”

The biological activity of soils is an essential parameter of their ecological status. The anthropogenic Heavy Metals (HMs) disturb the normal functioning of soil biota and, hence, the entire soil system. The aim of this work was to estimate the toxicity of loosely bound HM compounds in Haplic Chernozem using parameters of cellulose-degrading and urease activities. Contamination of Haplic Chernozem with Zn, Cd, Cu and Pb enlarged the group of mobile (loosely bound to soil) metal compounds, which includes exchangeable, complexed and specifically sorbed compounds of HMs. The increase of mobile HM forms content in soil inhibited the cellulose-degrading and urease activities after 30 days of the input of metal into the soil. A decrease in the toxic effect of metals on the studied parameters mainly occurred in the next 30 days. It was found that all HM forms similarly affected biological activity parameters. During two months from the moment of soil contamination with HMs, their toxic effect on cellulose-degrading and urease activities decreased. According to the degree of inhibition of biological activity in Haplic Chernozem, the studied metals formed the following series: Cd >Pb > Zn > Cu.

“…А строительство новых курортов, автомобильных дорог, нефтепроводов могут усилить загрязнение этих почв тяжелыми металлами (ТМ) и нефтью. Считается, что загрязнение ТМ (Minnikova et al, 2016) и нефтью относятся к наиболее опасной категории загрязняющих веществ и является важной гео-экологической проблемой (Urazmetov, Smirnova, 2014).…”

At the present time soils are exposed to increasing anthropogenic impact. The construction of new resorts, roads, pipelines -all of which can increase the soil pollution with heavy metals and oil. One of the most sensitive and informative indicators of the ecological condition of soils is the determination of the activity of the dehydrogenase. As a result, modeling studies found that pollution of chromium, copper, nickel, lead and oil reduces the dehydrogenase activity in all major soils of the Black Sea coast of the Caucasus: southern chernozem, brown typical, brown leached, brown carbonate, brown forest acidic, brown forest acid podzolized, sod-carbonate typical, sodcarbonate leached soils, zheltozem. As a rule, for all investigated heavy metals and oil was a direct relationship between the content in the soil contaminant and the degree of reduction of the biological indicator. The results indicate that the most significant negative impact has chrome. In terms of the negative impact of the change dehydrogenase activity in the studied soils Black Sea coast heavy metal oxides to form the following generalized sequence: Cr > Cu ≥ Ni ≥ Pb. A comparative evaluation of the stability of the dehydrogenase activity to contamination with heavy metals and oil for the main soils of the Black Sea coast of the Caucasus. Heavy metal pollution is least affected dehydrogenase activity typical sod-carbonate soils. For oil pollution on a particular indicator were more stable brown soil Resistance to the chemical contamination of soil depends on the nature and concentrations of pollutants in the soil, as well as the genetic properties of the soil itself.

“…Soil being most essential component of ecological system is highly contaminated worldwide by heavy metal (loid)s. Excessive accumulation of heavy metal (loid)s in the soils may cause deterioration of the soil ecosystem and create other environmental issues. Soil physico-chemical properties such as pH, electrical conductivity, cation exchange capacity, soil mineralogy, microbial and biological conditions and presence of soil inorganic and organic ligands greatly influence the bioavailable and mobile heavy metal(loid)s in soil (Shahid et al, 2012a(Shahid et al, , 2012b(Shahid et al, , 2012c(Shahid et al, , 2012dMinnikova et al, 2017). Numerous studies have reported heavy metal (loid)s build up in soil and associated risks to soil fertility/quality and biochemical activities (enzymes and microbes).…”

“…Numerous studies have reported heavy metal (loid)s build up in soil and associated risks to soil fertility/quality and biochemical activities (enzymes and microbes). Heavy metal(loid)s at the higher concentration are known to influence the microbial population of soil and their associated activities which may directly affect soil fertility (Minnikova et al, 2017). Pattnaik and Equeenuddin (2016) reported that soil enzyme activities are significantly negatively correlated with metal contents of Ni, Cu, Cr, Co, Mn and Zn.…”

, et al.. A comparison of technologies for remediation of heavy metal contaminated soils. Journal of Geochemical Exploration, Elsevier, 2016Elsevier, , 182, pp.247 -268. 10.1016Elsevier, /j.gexplo.2016 Any correspondence concerning this service should be sent to the repository administrator: staff-oatao@listes-diff.inp-toulouse.fr a b s t r a c tSoil contamination with persistent and potentially (eco)toxic heavy metal(loid)s is ubiquitous around the globe. Concentration of these heavy metal(loid)s in soil has increased drastically over the last three decades, thus posing risk to the environment and human health. Some technologies have long been in use to remediate the hazardous heavy metal(loid)s. Conventional remediation methods for heavy metal(loid)s are generally based on physical, chemical and biological approaches, which may be used in combination with one another to clean-up heavy metal(loid) contaminated soils to an acceptable and safe level. This review summarizes the soil contamination by heavy metal(loid)s at a global scale, accumulation of heavy metal(loid)s in vegetables to toxic levels and their regulatory guidelines in soil. In this review, we also elucidate and compare the pool of available technologies that are currently being applied for remediation of heavy metal(loid) contaminated soils, as well as the economic aspect of soil remediation for different techniques. This review article includes an assessment of the contemporary status of technology deployment and recommendations for future remediation research. Finally, the molecular and genetic basis of heavy metal(loid) (hyper)accumulation and tolerance in microbes and plants is also discussed. It is proposed that for effective and economic remediation of soil, a better understanding of remediation procedures and the various options available at the different stages of remediation is highly necessary.
