In laboratory model experiments, the ecotoxicity of Tl was assessed by changing microbiological, biochemical and phytotoxic properties soils in South Russia: ordinary chernozem (Haplic Chernozem (Loamic)), seropesks (Eutric Arenosol) brown forest slightly unsaturated soil Cambisol), differing granulometric composition, pH organic matter content. As a rule, there direct relationship between concentration degree deterioration studied properties. nitrate showed higher than oxide. The strongest ecotoxic effect manifested on 10 days after contamination, — 30 later. Restoration biological observed for 90 days. Ordinary greatest resistance to seropeski least. results obtained indicate high Tl.

For many decades, natural and modified clay minerals have been used as adsorbents to clean up aquatic soil ecosystems contaminated with organic inorganic pollutants. In this study, organoclays based on bentonite various amphoteric nonionic surfactants were synthesized tested effective sorbents for lead ions. The maximum values of R obtained when describing the sorption processes using Langmuir model, which ranged from 0.97 0.99. adsorption ions by these was investigated different models including Langmuir, Freundlich, BET. It found that, according limiting equation, formed an increasing series: organoclay cocamide diethanolamine < lauramine oxide sodium cocoiminodipropionate disodium cocoamphodiacetate alkyl polyglucoside. Gibbs energy all analyzed samples calculated be negative, indicating spontaneity cation process in forward direction. value capacity cations organoclay-based polyglucoside 1.49 ± 0.05 mmol/g 0.523 0.003 determined BET model. modifying bentonite, there increase negative zeta potential compared initial mineral, clearly enhanced their electrostatic interactions positively charged hypothesized, physicochemical principles, that exchange is main mechanism absorption. Based chemical approaches, absorb mainly through mechanisms attraction, ion exchange, complexation well formation insoluble precipitates. Organoclays surfactants, other hand, (including chelation) comparison isotherms allows us find most accurate match between model experimental data, better understand nature involved.

Introduction. Тhe municipal solid waste of pollution negatively affects on the state environment, since during their storage territory landfills and adjacent territory, accumulation heavy metals (HM) can change biological indicators soil conditions: microbiological, biochemical, phytotoxic. The aim study was to assess influence toxic effect landfill “Azov” in Rostov region ecological soil. Materials methods. It explored condition ordinary chernozem (140, 260, 380, 540 m). content soil, such as chromium (Cr), strontium (Sr), zinc (Zn), vanadium (V), copper (Cu), nickel (Ni), cobalt (Co), lead (Pb), arsenic (As) were defined. is assessed by sensitive informative-biological pollution: abundance bacteria genus Azotobacter, total prevalence bacteria, activity catalase, dehydrogenases. Results. Soils found contaminate with MAC / TAC (exceeding 7 times at exceeding 4 6 territory). Pollution according German MACs exceeded 1.4 times). highest concentration prevailed body landfill. Depending distance from decreased. HM contamination leads negative consequences for chernozem: number decreases (until 95% control), Azotobacter (up catalase 25% control) dehydrogenase 30% increased phytotoxicity 60% control). be concluded that exploitation a deterioration environmental situation beyond. Limitations. ecotoxic HMs soils less buffered will higher than chernozems studied article. Conclusion. Landfill impact phytotoxic parameters negatively. This problem connects which get into operation most informative are length radish roots.

Soil contamination with rare elements such as silver (Ag), bismuth (Bi), tellurium (Te), and thallium (Tl) less studied, but their toxicity no high than in other heavy metals. Activity enzymes great importance for healthy functioning soils, agroecosystem services, fertility. It necessary to assess ecological state black using most sensitive informative indicators soils—their enzymatic activity. The objective this research was evaluate changes activity five priority (catalase, dehydrogenases, invertase, phosphatase, urease) when contaminated oxides nitrates Ag, Bi, Te, Tl a laboratory model experiment. integral assessed by integrated index A comparison each element, according activity, allowed us establish that Ag oxide more toxic nitrate; Bi equivalent its Te nitrates. When oxides, invertase urease (Bi, Tl), phosphatase (Te). nitrates, (Ag) Tl, Te). catalase least sensitive.
