“…Various authors reported increased solubility of heavy metals and arsenic in soils caused by the presence of plant cover or induced by the products that are formed in soils from decomposing plant residues. In particular, the processes of forest litter transformation may lead to increased solubility of various elements, as they deliver organic and inorganic compounds into draining water, stimulate biological activity, and additionally may affect redox conditions (Kalbitz and Wennrich 1998;Karczewska et al 2013aKarczewska et al , 2017Kabała et al 2014;Berg 2017;Cuske et al 2017).…”

Purpose Soils that develop on the dumps in historical arsenic mining sites contain high concentrations of As thus constituting a serious environmental risk. This study was aimed to examine the changes in arsenic solubility in mine soils as induced by organic matter introduced with forest litter. Materials and methods Four large samples of initially developed soils were collected from the dumps remaining in former mining sites and were incubated for 90 days at various moistures: 80% of maximum water holding capacity and 100% (flooded conditions), with and without addition of beech forest litter (BL), 50 g/kg. Soils contained up to 5.0% As. Soil pore water was collected periodically with MacroRhizon suction samplers and examined on As, Mn, and Fe concentrations, pH, Eh, and dissolved organic carbon (DOC). The properties of dissolved organic matter were characterized by UV-VIS spectroscopic parameters A4/A6 and SUVA 254 . Results and discussion Application of BL resulted in an intensive release of As from soils, particularly at 100% moisture. As concentrations in soil pore water increased strongly during the first 2 or 4 weeks of incubation and then started to decrease in all cases, except for one flooded soil. As was released particularly intensively from carbonate-containing soils. The mechanisms of As mobilization, including reductive dissolution of Mn and Fe oxides and the competition with DOC for sorption sites on the oxides, were discussed as related to soil properties. Pore water concentrations of DOC were increasing at the beginning of incubation and started to decrease after two or four weeks. Spectroscopic parameters of dissolved organic matter in ZS soils indicated increasing aromaticity and progress of humification. Conclusions Forest litter introduced to mine dump soils causes a mobilization of As into soil pore water. This effect, particularly strong in carbonate-rich soils, is apparently related to high concentrations of DOC and usually declines with time, which may be explained by the progress in humification. The relationships between DOC properties and As speciation in soil pore water should be dissected for better interpretation of experimental results.

“…Soil treatment with inorganic fertilizers (F) proved to be particularly beneficial for Agrostis capillaris grown in soils 1 and 3 (Figure 1a). Considerable improvement of the growth of grasses resulting from soil fertilization, and associated reduction in As concentrations in grass shoots (Figure 1b, discussed further in the text), should be emphasized, because fertilization of As-rich soils, especially application of organic fertilizers, results usually in an accelerated release of As from the soil solid phase, increase in its solubility and elevated As concentrations in soil pore water, which were documented in earlier studies [11,34,38,43].…”

“…The release of As from the soil solid phase is determined by its origin and related primary physical and mineralogical forms, by the abundance of As binding components, mainly iron oxihydroxides, and by the presence of components capable to compete with As for specific sorption sites [1,19,20]. Such a competition can be caused by phosphates [33][34][35] or by dissolved or colloidal organic matter [11,[36][37][38][39] introduced into the soil solution with inorganic or organic fertilizers.…”

The study focused on two grass species Holcus lanatus and Agrostis capillaris abundant in the sites of former As mining and processing in the Sudetes. Arsenic uptake from soils was examined to assess a risk associated with its accumulation in grass shoots and to check its dependence on soil fertilization. The research involved a field study and greenhouse experiment. In the field study, soil and plant samples were collected from 33 sites with 72–98,400 mg/kg total soil As. Arsenic uptake by grasses differed widely. Both species indicated a strategy typical for eliminators, although As concentrations in more than 50% of the shoot samples exceeded 4 mg/kg, a maximum permissible value for fodder. In the greenhouse experiment, commercial cultivars of both species were grown in five soils containing 394–19,600 mg/kg, untreated and fertilized. All seedlings died in the soil with highest total As, and considerable phytotoxicity was observed in other soils, particularly in nonfertilized ones. Fertilization resulted in the improvement of plant growth and reduction of As uptake except for Agrostis capillaris fertilized with manure. Further research should focus on identifying tolerant genotypes growing in extremely enriched sites and analysis of factors that will efficiently reduce As phytoaccumulation.

“…Ryegrass was selected because of its fast growth, large biomass, fibrous root system with a dense rhizosphere and established remediation potential. [70][71][72] An increase in initial Cr(VI) concentration improved its removal efficiency, and long-term operation of the PMFC indicated that the system was stable. A combination of bioelectrochemical reduction, phytoaccumulation and precipitation was the basis for the removal of Cr(VI) in the PMFC.…”

Rapid urbanization and industrialization has led to the indiscriminate discharge of heavy metals into the environment. Hexavalent chromium (Cr(VI)), a lethal, carcinogenic and genotoxic heavy metal frequently found in industrial effluent, poses a serious threat to human health. On the other hand, there is a global energy crisis prevalent owing to the scarcity of resources and huge energy demand. An emerging innovative technology which utilizes the biocatalytic activity of microbes for electron production and offers a dual solution for simultaneous reduction of Cr(VI) and generation of bioelectricity is the microbial fuel cell (MFC). The success of the MFC depends on variables such as cell configuration, pH, electrode materials, effect of microbial communities and operational conditions. This review provides a critical insight on the developments in the field of MFCs with abiotic and biotic cathodes, integrated systems, plant‐ and soil‐based designs for treatment of Cr(VI)‐laden effluent and sustainable energy recovery. © 2019 Society of Chemical Industry
