Polluted Soils

Soils polluted with heavy metals have become common across the globe due to increase in geologic and anthropogenic activities. Plants growing on these soils show a reduction in growth, performance, and yield. Bioremediation is an effective method of treating heavy metal polluted soils. It is a widely accepted method that is mostly carried outin situ; hence it is suitable for the establishment/reestablishment of crops on treated soils. Microorganisms and plants employ different mechanisms for the bioremediation of polluted soils. Using plants for the treatment of polluted soils is a more common approach in the bioremediation of heavy metal polluted soils. Combining both microorganisms and plants is an approach to bioremediation that ensures a more efficient clean-up of heavy metal polluted soils. However, success of this approach largely depends on the species of organisms involved in the process.

The Antarctic

Human activity in the Antarctic requires the use of petroleum hydrocarbons as the main energy source for a variety of operations. In the current study, in situ soil microcosms were constructed in the proximity of the Brazilian Antarctic Station Comandante Ferraz, King George Island, South Shetland Islands, to analyse the effect of oil amendment on the indigenous bacterial community in contaminated and uncontaminated sites to assess the potential for bioremediation. Microcosms were sampled for heterotrophic and hydrocarbon-degrader bacterial counts, pH, temperature, moisture, nutrient levels and petroleum hydrocarbons. Total organic carbon, nitrogen and phosphorus contents were generally low in the Antarctic cryosols. According to statistical analysis based on Colony Forming Unit numbers, significant bacterial populations were present in all microcosms, with larger numbers observed in oil amended than in non-amended soils. Aliphatic and aromatic fractions of diesel fuel were detected in the soil microcosms, and significant quantities were removed during the experiment. These results strongly suggest that the cold-adapted bacterial community present in soils around the Brazilian Antarctic station has the potential to adapt and utilize the oil as a carbon source. This knowledge can contribute both to bioremediation technology and the goals of the the Antarctic Treaty which prohibits the introduction of foreign organisms into the region.

In-situ remediation of heavy-metal-contaminated soil in farmland using phytostabilization combined with soil amendments is a low-cost and effective technology for soil pollution remediation. In this study, coconut shell biochar (CB, 0.1% and 0.5%), organic fertilizer (OF, 3.0%), and Fe-Si-Ca material (IS, 3.0%) were used to enhance the phytostabilization effect of ramie (Boehmeria nivea L.) on Cd and Pb in highly polluted soils collected at Dabaoshan (DB) and Yangshuo (YS) mine sites. Results showed that simultaneous application of CB, OF, and IS amendments (0.1% CB + 3.0% OF + 3.0% IS and 0.5% CB + 3.0% OF + 3.0% IS, DB-T5 and DB-T6) could significantly increase soil pH, reduce the concentrations of CaCl2-extractable Cd and Pb, and increase the contents of Ca, P, S, and Si in DB soil. Under these two treatments, the growth of ramie was significantly improved, its photosynthesis was enhanced, and its levels of Cd and Pb were reduced, in comparison with the control (DB-CK). After applying DB-T5 and DB-T6, the concentrations of Cd and Pb in roots were decreased by 97.7–100% and 64.6–77.9%, while in shoots they were decreased by up to 100% and 92.9–100%, respectively. In YS-T4 (0.5% CB + 3.0% OF), the concentrations of Cd and Pb in roots were decreased by 39.5% and 46.0%, and in shoots they were decreased by 44.7% and 88.3%. We posit that phytostabilization using ramie and amendments could reduce the Cd and Pb bioavailability in the soil mainly through rhizosphere immobilization and plant absorption. In summary, this study suggests that the use of tolerant plant ramie and simultaneous application of coconut shell biochar, organic fertilizer, and Fe-Si-Ca materials is an effective stabilization strategy that can reduce Cd and Pb availabilities in soil. Ultimately, this strategy may reduce the exposure risk of crops to heavy metal pollution in farmland.
