“…Plants can uptake contaminants through their roots and leaves and these substances can biomagnificate within food chains, leading to disease and/or death of animals including human beings (Vargas Rojas et al, 2016). The case study presented by Ding et al (2016) in China highlights the main accumulation of Cd, As and Pb in rice grain (Oryza sativa) that will not only decrease rice production but also present health risks to consumers. In addition, and by changing the ability to sustain a certain diversity of plant species, the presence of metals in soils can change the water holding capacity, affecting therefore other soil living organisms like invertebrates, essential for different functions and services provided by soil ecosystems.…”

Changes in Soil Ecosystem Structure and Functions Due to Soil Contamination

Soil ecosystems are nowadays exposed to several physical, chemical and biological stressors, which are directly or indirectly related to anthropogenic activities. This chapter covers how contaminants affect the soil ecosystem structure, changing soil functions and services. Soil ecosystem structure is constituted by dynamic interactive abiotic and biotic compartments, dependent on major key factors like water and light. By changing this balanced system, soil functions are also impaired as they are strictly dependent on this structure and biodiversity. Soil functions include carbon transformations, nutrient cycling, maintenance of the structure itself, and regulation of biological populations. Activities like mining, agriculture, forestry or waste disposal are often responsible for the unbalance of soil structure and functions, by jeopardizing majorly the functional biodiversity compartment of the ecosystem. Therefore, the provision of goods along with ecosystem services will be also affected. Valuing soil ecosystem services is a difficult task and often lacking at the policymaking level, as the costs of services losses can go unnoticed. Therefore new strategies should be implemented to bring the concepts of structure, functions, services and goods on board at the regulation level.

“…The utilization of plants for the management of polluted land has been described in order to limit the dissemination of pollutants (phytostabilisation). In addition, the cultivation of economic plants, such as fiber or bioenergy crops, can be considered to contribute to the socio-economic development of contaminated areas [8,9].…”

Ramie plants (Boehmeria nivea) have been cultivated on ion-adsorption rare earth elements (REEs) mine tailings and showed a low ability to accumulate REEs, especially in the stems (REE= 24±17 mg kg -1 ) with higher concentration in leaves and roots (REE= 57 to 66 mg kg -1 ). Ramie individual fibers were isolated using three degumming processes: a traditional alkali treatment (AT), a steam explosion (SE) treatment after a neutral (SEN) or after a basic (SEB) impregnation. Cellulose-rich (> 80%) fine fibers with very low amounts of non-cellulosic sugars (<5%), low REE concentrations (REE ≈ 4-6 mg kg -1 ) and a high mechanical strength (tensile strength ≈ 260-540 cN/fiber, breaking point ≈ 20-50 cN/fiber) have been produced. However, SE degumming resulted in more degraded fibers with cracks slightly affecting their tensile properties.

“…The incorporation of HMs into the soil leads to a transformation of soil properties with rapid incorporation into biological cycles. These soil property transformations lead to suppression of critical soil ecosystem functions that support primary production and maintain microbiological communities, sustain biodiversity, promote sequestration of greenhouse gases, provide water and promote nutrient supply ( Ding et al., 2018 ).…”

The long-term emission impacts of the nickel processing industry in the Kola Peninsula, the largest source of sulfur dioxide and heavy metals emissions in Northern Europe, have created vast technogenic barrens near the mineral industry complexes. The pace of rehabilitation using the improved remediation technologies to enhance sustainable environmental management and regional economic development is of crucial social and economic importance. In a 120-day incubation experiment, we evaluated the prospects for the restoration of two soils at different degradation stages via carbon pool regulation comparing to mineral ameliorants – NPK fertilizer, and liming agent. Organic additives used included a humic preparation based on an alkaline brown coal extract, wood-derived biochar, and peat-derived gel, supplied by mycorrhizae fungi. The results demonstrate that the selected organic amendments are suitable for restoration of acidic metal contaminated soils. Specifically, the treatments provided a measurable increase in soil carbon content, a marked decrease in acidity, a decrease in extractable metal contents, together with an enhanced nutrient uptake and vegetative growth. A stabilization effect increased from biochar to peat-gel, liming agent and humic preparation, with an accompanying increase in soil pH. Although biochar showed a reduced ability to metal stabilization, the associated treatments were the most productive. The most effective amendments in multi-metallic contaminated soils need to be able to stabilize bioavailability of metals, adjust pH to the optimum for plant growth, and regulate nutrient consumption.
