The effect of diatomite and tripoli added into the soil artificially contaminated with benzo[a]pyrene was studied. A decrease in the toxic effect of BaP on barley plants was established when diatomite and tripoli were added as ameliorants to contaminated soil. The improvement of plants grown сharacteristics on soils contaminated with BaP with the addition of diatomite and tripoli was shown up to 2-4 times compare to contaminated samples.

The results of an experiment on cleaning oil-contaminated soil and accelerating the restoration of its fertility with the aid of combined biopreparations containing bacteria that degrade oil and microorganisms that can stimulate the growth and development of plants. It is shown that the introduction of bacterial mixtures reduced the oil content by 3.1–3.6 times and increased by 2-3 orders the number of basic physiological groups of soil microorganisms participating in its transformation, and also accelerated the germination of seeds (for 2 days) and the beginning (for 6–7 days) of all stages of oat development, used as a phytomeliorant. The most effective was a biopreparation consisting of a consortium of microorganisms Acinetobacter calcoaceticus IB DT-5.1/ 1 and Ochrobactrum intermedium IB DT-5.3/2 and strains of Pseudomonas koreensis IB-4 and Paenibacillus ehimensis IB 739, which, among other things, increased the mass of oat shoots in 2.3–2.6 times and their length is 54.0–77.8% compared to plants in the soil untreated with bacteria with oil.

Abstract Aim The study was undertaken to determine the effect of amendments used in remediation of cobalt-contaminated soil on the macroelement content of all organs of spring barley (the main crop) and white mustard (the after-crop). Methods In the experiment, six blocks were selected: without amendments; with manure (bovine, granulated); clay; charcoal; zeolite; and with calcium oxide (50%). In each of the blocks, increasing doses of cobalt were applied: 0, 20, 40, 80, 160, and 320 mg kg−1 of soil. Results Cobalt-contaminated soil and amendments application had a significant effect on macroelement content of all organs of both plants. Conclusions In blocks without amendments, 80 mg Co kg−1 contributed the most increase in nitrogen, sodium, and calcium contents of both organs of spring barley. Cobalt-contaminated soil increased content of all macroelements in white mustard organs. Application of amendments to soil had strong impact on phosphorus, sodium, and calcium contents of organs of both plant species, compared to the control block (without amendments). Among the amendments, manure had the greatest effect on the content of macroelements in plants. Manure increased phosphorus, potassium, and sodium contents of all organs of both plants. The optimal content of macroelements is extremely important for the growth and development of plants, especially on soils contaminated with trace elements, including cobalt.

The present laboratory study was carried out to determine the effect of the metal contaminated soil on the survival, growth and development of Eisenia fetida. Metal contaminated soil samples were collected from five different sites of Ludhiana city which is an industrial hub of Punjab. Maximum heavy metal concentrations were recorded in soil sample taken from hambran around the Buddha Nullah and minimum concentration of heavy metal from haibowal. The level of heavy metals chromium and nickel (347 ppm and 189 ppm) were higher than permissible limits according to CCME (2001), whereas lead (42.6 ppm) was within permissible limits. Adult E. fetida were exposed to different concentrations of heavy metals in artificial soil for 28 days. Significant effects were observed on growth and reproduction of the tested organisms. There was 100% survival of E. fetida in soil amended with lead, chromium and nickel along with morphological abnormalities such as extrusion of coelomic fluid. It was observed that the worms in the low and high doses of heavy metal treated substrate produced cocoons with a one week and two week delay, respectively, vis-a-vis the control group. Furthermore, the emergence of hatchlings started one week earlier in control than in soil treated with medium and high concentration of metals. It is safely concluded that presence of heavy metal in soils adversely affects the growth, reproduction and development of E. fetida. Results ofthe study indicated that reproduction was more sensitive to higher concentrations of heavy metal contaminated soil than survival or weight change.

Positive Effect

The effect of various doses of diatomite introduced into soil artificially contaminated by benzo[a]pyrene was analyzed. The negative effect of benzo[a]pyrene on the growth of barley (Hordeum sativum distichum) seedlings and reduction of toxic effect of polyarene on plants after implementation of diatomite as a sorbent into contaminated soil are shown. A significant increase (by 2–3 times) of the plant growth in contaminated soil with the addition of diatomite has been revealed. The introduction of 2.5% diatomite into contaminated soil had the significant positive effect on barley seedlings.
