“…This is generally consistent with most studies that showcase high levels of metal uptake by Typha sp. than any other species for most effluents (Yang & Ye, 2009;Vymazal, 2010;Kumari & Tripathi, 2015;García et al, 2017). However, the rates of Cu and Zn absorptions are also dependant on the inlet concentrations.…”

An artificial wetland was computationally modelled using STELLA®, a graphical programming tool for an Au-Cu mine site in Central-west NSW, the aim of which was to offer a predictive analysis of a proposed wetland for Cu, Zn and Mn removal using Typha domingensis as the agent. The model considers the important factors that impact phytoremediation of Cu, Zn and Mn. Simulations were performed to optimise the area of the wetland; concentration of Cu, Zn and Mn released from mine (AMD); and flow rates of water for maximum absorption of the metals. A scenario analysis indicates that at AMD = 0.75mg/L for Cu, Zn and Mn, 12.5, 8.6, and 357.9 kg of Cu, Zn and Mn, respectively, will be assimilated by the wetland in 35 years, which would be equivalent to 61 mg of Cu/kg, 70 mg of Zn/kg and 2,886 mg of Mn/kg of T. domingensis, respectively. However, should Cu, Zn and Mn in AMD increase to 3 mg/L, then 18.6 kg of Cu and 11.8 kg of Zn, respectively, will be assimilated in 35 years, whereas no substantial increase in absorption for Mn would occur. This indicates that 91 mg of Cu, 96 mg of Zn and 2917 mg of Mn will be assimilated for every kg of T. domingensis in the wetland. The best option for Cu storage would be to construct a wetland of 50,000 m 2 area (AMD = 0.367 mg/L of Cu), which would capture 14.1 kg of Cu in 43 years, eventually releasing only 3.9 kg of Cu downstream. Simulations performed for a WA of 30,000 m 2 indicate that for AMD = 0.367 mg/L of Zn, the wetland captures 6.2 kg, releasing only 3.5 kg downstream after 43 years; the concentration of Zn in the leachate would be 10.2 kg, making this the most efficient wetland amongst the options considered for phytoremediating Zn. This work will help mine managers and environmental researchers in developing an effective environmental management plan by focusing on phytoremediation, with a view at extracting Cu, Zn and Mn from the contaminated sites.

“…Within the in-situ system of Scenario 1, the value of efficacy of the reduction of the flow of cadmium through the method of chemical oxidation was adopted on the basis of book values, by applying H2O2 as an oxidizing agent, and it amounts to 95 %, while through the method of phytoremediation using plant species Typha domingensis, Brassica napus and Typha latifolia L., amounts to 81 % (Seol and Javandel, 2008;Lavagnolo et al, 2016;Mojiri et al, 2016;Antić et al, 2017;Ferniza-García et al, 2017).…”

“…Efficacy of the reduction of cadmium flow by applying the phytoremediation method was tested experimentally several times by experts. It was established that efficacy amounting to 81 % was achieved by using plant species Typha domingensis, Eichhornia crassipes and Typha latifolia L. (Mojiri et al, 2016;Antić et al, 2017;Ferniza-García et al, 2017). Within the treatment at the cement plant, 99.98 % of the flow of cadmium was concentrated in clinkers, and the remaining 0.02 % through waste gases are emitted in the environment (Korzun and Heck, 1990;Mitchell et al, 1992).…”

“…Both policy makers and scientists have continued to seek novel ways of managing contamination from organic and inorganic compounds in soil. Phytoremediation, precipitation, ion exchange, membrane filtration and coagulation are some of the ways that have been used for the treatment of pollution in soil and water (Ferniza-García et al 2017;Paz-Ferreiro et al 2014). However, these techniques are not always cost-effective and may end up generating contaminant-rich waste.…”

Advances in research on the use of biochar in soil for remediation: a review

Purpose Soil contamination mainly from human activities remains a major environmental problem in the contemporary world. Significant work has been undertaken to position biochar as a low-cost material useful for the management of contaminants in various environmental media notably soil. Here, we review the increasing research on the use of biochar in soil for the remediation of some organic and inorganic contaminants. Materials and methods Bibliometric analysis were carried out within the past 10 years to determine the increasing trend in research related to biochar in soil for contaminant remediation. Five exemplar contaminants were reviewed in both laboratory and field-based studies. These included two inorganic (i.e. As and Pb), and three organic classes (i.e. sulfamethoxazole, atrazine, and PAHs). The contaminants were selected based on bibliometric data and as representatives of their various contaminant classes. For example, As and Pb are potentially toxic elements (anionic and cationic, respectively) while sulfamethoxazole, atrazine, and PAHs represent antibiotics, herbicides and hydrocarbons, respectively. Results and discussion The interaction between biochar and contaminants in soil is largely driven by biochar precursor material and pyrolysis temperature as well as some characteristics of the contaminants such as octanolwater partition coefficient (KOW) and polarity. The structural and chemical characteristics of biochar in turn determine the major sorption mechanisms and define biochar's suitability for contaminant sorption. Based on the reviewed literature, a soil treatment plan is suggested to guide the application of biochar in various soil types (paddy soils, brownfield and mine soils) at different pH levels (4-5.5) and contaminant concentrations (< 50 and > 50 mg kg-1). Conclusions Research on biochar has grown over the years with significant focus on its properties, and how these affect biochar's ability to immobilize organic and inorganic contaminants in soil. Few of these studies have been field-based. More studies with greater focus on field-based soil remediation are therefore required to fully understand the behavior of biochar under natural circumstances. Other recommendations are made aimed at stimulating future research in areas where significant knowledge gaps exist.
