“…For the organic source of nutrition, 2.5% MSC was added to each pot, which contained traces of Pb and Cu 14 . Inactivated BB can promote dissolved organic matter (DOM), which may form soluble Pb and Cu complexes 15, 16 . The HMs concentration is far higher in FC than in TG soil.…”

“…They include, CaO, phosphate fertilizers, fly ash, medical stone, organic waste (compost, crop residues and bio-solid compost), zeolite and biochar 12–14 . Among these practices, biochar is widely used for HMs immobilization in polluted soil 15 . Biochar application is an old practice originating from slash-and-burn agriculture, which may be a method to limit HMs (Zn, Cd, and Pb) mobility from the soil to living matrices 16, 17 .…”

Anthropogenic activities have transformed the global geochemical cycling of heavy metals (HMs). Many physical, chemical and biological methods are used to reduce the toxicity of HMs to humans, plants and environment. This study aimed to investigate the immobilization and phytotoxicity reduction of HMs after application of bamboo biochar (BB) in mine-polluted soil in Feng county (FC) and Tongguan (TG). The results showed that BB application to contaminated soil immobilized HMs (Zn, Pb, Cd and Cu). The soil pH and EC increased and the bioavailability of HMs decreased in FC and TG, whereas Pb and Cu increased in TG soil. The addition of BB reduced HMs uptake in the shoot/root of Brassica juncea. Physiological responses showed that BB application improved the shoot/root growth, dry biomass, and enhanced the chlorophyll (a and b) and carotenoid concentrations in Brassica. The incorporation of BB improved the soil health and accelerated enzymatic activities (β-glucosidase, alkaline phosphatase and urease) in HMs polluted soils. Antioxidant activities (POD, PPO, CAT and SOD) were also used as biomarkers to determine the negative effects of HMs on the growth of Brassica. Overall, the immobilization potential and phytotoxicity reduction of HMs were confirmed by BCF, TF and MEA for both soils.

“…Extensive work has been done on how biochar might mitigate global warming by sequestering C from atmosphere into soil (Dong et al, 2013;Lehmann, 2007). Numerous studies showed that biochar has potential for remediating soils contaminated with heavy metals and organic compounds (Ahmad et al, 2015;Beesley and Marmiroli, 2011). The properties of biochar produced from different feedstocks and pyrolysis conditions vary widely.…”

“…Although partly explored, the effects of biochar on mobility and bioavailability of heavy metals have been reported by others (Beesley et al, 2010;Fellet et al, 2011;Rizwan et al, 2015). To our understanding, limited research has been directed to determine the redistribution of multiple heavy metal contaminants in soils amended with different types of biochar (Ahmad et al, 2016a(Ahmad et al, , 2016b.…”

Anthropogenic activities, such as industrial expansion, smelting, mining and agricultural practices, have intensified the discharge of potentially toxic trace elements (PTEs) into the environment, threatening human health and other organisms. To assist phytoremediation by sorghum in soil contaminated by smelters/mines in Feng County (FC), a pot experiment was performed to examine the phytoremediation potential of Streptomyces pactum (Act12) + biochar. The results showed that root uptake of Zn and Cd was reduced by 45 and 22%, respectively, while the uptake of Pb and Cu increased by 17 and 47%, respectively. The shoot and root dry weight and chlorophyll content improved after Act12 inoculation. β-glucosidase, alkaline phosphatase and urease activities in soil improved and antioxidant activities (POD, PAL, PPO) decreased after application of Act12 + biochar due to a reduction in stress from PTEs. BCF, TF and MEA confirmed the role of Act12 in the amelioration and translocation of PTEs. PCA analysis showed a correlation between different factors that affect the translocation of PTEs. Overall, Act12 promoted the phytoremediation of PTEs. Field experiments on Act12 + biochar may provide new insights into the rehabilitation and restoration of soils contaminated by mines.
