TLDR
The application of biochar for in situ metal immobilization can be feasible provided soil pH is monitored over time, and the time required to reach a hazardous pH can be predicted to be longer after biochar application.About:

Effect of bamboo and rice straw biochars on the mobility and redistribution of heavy metals (Cd, Cu, Pb and Zn) in contaminated soil.
Kouping Lu,Xing Yang,Gerty Gielen,Nanthi Bolan,Yong Sik Ok,Nabeel Khan Niazi,Song Xu,Guodong Yuan,Xin Chen,Xiaokai Zhang,Dan Liu,Zhaoliang Song,Xingyuan Liu,Hailong Wang +13 more
TL;DR: The results demonstrated that the rice straw biochar can effectively immobilize heavy metals, thereby reducing their mobility and bioavailability in contaminated soils.

Effect of pyrolysis temperature, heating rate, and residence time on rapeseed stem derived biochar
Bin Zhao,David O'Connor,Junli Zhang,Tianyue Peng,Zhengtao Shen,Zhengtao Shen,Daniel C.W. Tsang,Deyi Hou +7 more
TL;DR: In this paper, the pyrolysis dependent properties of rapeseed stem biochar were investigated under various temperatures (200-700°C, in 50°C intervals), heating rates (1, 5, 10, 15, 20, 20°C/min), and residence times (10,20, 40, 60, 80, 100min).

Biochar application for the remediation of heavy metal polluted land: A review of in situ field trials
David O'Connor,Tianyue Peng,Junli Zhang,Daniel C.W. Tsang,Daniel S. Alessi,Zhengtao Shen,Zhengtao Shen,Nanthi Bolan,Deyi Hou +8 more
TL;DR: It was found that the use of biochar may help increase crop yields on polluted land, and thus reduce the amount of mineral fertilizer used in the field, and in order to maximize the benefits ofBiochar addition, farmers need to accept that the dosage rates of mineral fertilizers should be reduced.

Quantitative assessment of worldwide contamination of air, water and soils by trace metals
Jerome O. Nriagu,Jozef M. Pacyna +1 more
TL;DR: Calculated loading rates of trace metals into the three environmental compartments demonstrate that human activities now have major impacts on the global and regional cycles of most of the trace elements.

A handful of carbon
TL;DR: On the climate change mitigation front, the incorporation of ‘biochar’ into the soil is one idea gaining support, and Johannes Lehmann argues that trapping biomass carbon in this way is more effective than storing it in plants and trees that will one day decompose.
