“…This can be achieved either through changes in soil pH (e.g. an increase in pH mobilizes the oxyanion As, while a decrease in pH mobilizes most metallic cations) (Huang & Chen, 2003;Zheng et al, 2019), or the addition of F I G U R E 3 Concentrations of metals in plant tissues that would be need to achieve a gross value of $500 ha −1 .

To promote human well-being and ensure healthy lives, the United Nations has set an ambitious sustainable development goal to reduce illnesses and deaths associated with soil contamination by 2030 (UN, 2015). Soil is a fragile, nonrenewable resource that is fundamental to life on earth (FAO, 2015;Hou et al., 2020). However, anthropogenic activities have led to widespread soil degradation and contamination (FAO, 2018). In Europe, there are approximately 2.5 million sites that are potentially contaminated by heavy metals and organic contaminants (EEA, 2018). In USA, 235,000-355,000 sites need to be remediated (US EPA 2004). In China, it is estimated that 16.1% of the nation's land contains

“…Biochar amendment could enhance the phytoremediation effects via promoting plant growth. Zheng et al (2019) found that rice straw biochar could assist phytoextraction of As in a paddy soil by accelerating As uptake and translocation in As hyperaccumulator (Pteris vittata L.) (Zheng et al 2019). Manure waste and tea waste biochars were also reported to facilitate the phytoremediation of heavy metals in contaminated soils or sediments by improving plant growth and mitigating the oxidative stress.…”

Biochar, derived from thermal pyrolysis of biomass, has been regarded as a low-cost, sustainable and beneficial material and widely applied in agriculture, environment and energy during the last two decades. To elucidate the research status timely and future trends in biochar field, CiteSpace is used to systematically analyze the related literature retrieved from the Web of Science core collection in 2019. Based on the keywords clustering analysis, it was found that "biochar production", "organic pollutants removal", "heavy metals immobilization", "bioremediation" were the main hotspots in research covering biochar. "Bioremediation" is an emerging topic and deserves extensive attention due to its highly effective and environmentally friendly treatment of pollutants. Improving the phytoremediation effect, immobilizing functional microorganisms on biochar, and using microorganisms as raw materials to produce biochar were the common methods of biochar-assisted bioremediation. While studies focused on "soil quality and plant growth" and "biochar and global climate change" decreased, investigations concentrated in the toxicity of biochar to soil biota and ruminants are sustainably growing. Research on direct and catalytic thermal pyrolysis of green waste (mainly microalgae) for biofuels (bio-oil, biodiesel, syngas, etc.) and biochar production is increasing. Converting municipal wastes (e.g., sewage sludge, fallen leaves) into biochar through pyrolysis was a suitable treatment for municipal waste and became a popular topic in recent time. Moreover, the biochar produced from these municipal wastes exhibited excellent performance in the removal of pollutants from wastewater and soil. This review may help to identify future directions in biochar research and applications.

Diffusive gradients in thin films for the measurement of labile metal species in water and soils: a review

et al. 2021

View full text Add to dashboard Cite

The determination of the concentration of an environmental pollutant is not sufficient to assess the related health risk because this pollutant may not be bioavailable. Therefore, methods to determine pollutant bioavailability are more relevant to assess toxicity than measuring the total concentration. For instance, the diffusive gradient in thin films (DGT) is an in situ dynamic technique used to measure the concentration of labile compounds in the environment. Here we review the latest developments achieved in speciation and bioavailability of metals and metalloids using this technique. We detail the technique, common binding agents and diffusive gels. We give laboratory procedures to prepare the gels, and we explain calculations using the DGT-induced fluxes in soils (DIFS) modeling. DIFS models can predict the resupply capacities from soils to porewater, and the uptake of trace elements by plants. Procedures for in situ field deployments, including issues of biofilm growth, are also discussed.
