“…Biochar has attracted widespread interest globally because of its applications as soil amendment, pollution treatment, carbon sequestration, etc. Woolf et al 2010;Beesley and Marmiroli 2011;Zhang et al 2013;Muter et al 2014). These applications of biochar can be attributed, in part, to its developed pore structure, large specific surface area, abundant surface functional groups, and stable carbon skeleton (Lehmann and Joseph 2009;Guo et al 2014;Ścisłowska et al 2015).…”

“…Therefore, the impact of biochar on immobilisation of heavy metals in clay-rich soils is worth being investigated. However, the majority of studies to date have investigated the performance of biochar in sanddominated soils, as indicated in Table S1 [3, [10][11][12][13][14]. Studies that applied biochar on clay-rich soils are very limited, leading to a poor understanding of the performance of biochar on clay soils contaminated with heavy metals and the remediation mechanisms involved.…”

Salisbury biochar (produced from British broadleaf hardwood) with two different particle sizes (≤ 2 mm and ≤ 0.15 mm) was applied on a kaolin with three different lead (Pb 2+ ) contamination levels (50 mg/kg, 300 mg/kg and 1000 mg/kg) at the dosage of 1% in w/w. The short-term impact of biochar on the mobility and speciation of Pb 2+ in the kaolin was investigated using attenuation periods of 1, 7and 28 days. This paper suggests the inefficiency of biochar treament on heavy-metal contaminated clay-rich soils. Therefore a laboratory treatablity study with respect to the soil type may be crucial when large-scale biochar applications in heavy-metal associated soil remediation are evaluated.

“…Because biochar has a low production cost and strong adsorption for organic pollutants (e.g., polycyclic aromatic hydrocarbons (PAHs) as well as antibiotics) and heavy metals (e.g., Pb, Cu, Zn, and Cd) [10][11][12], it has the potential to be applied as an adsorbent for environmental protection on a large scale.…”
