Remediation of heavy metal contaminated soils by biochar: Mechanisms, potential risks and applications in China.
TL;DR: Recent progresses in understanding metal-biochar interactions in soils, potential risks associated with biochar amendment, and application of biochar in soil remediation in China indicate that the remediation effect depends on the characteristics of both biochar and soil and their interactions.
Understanding the Mechanisms of Lead, Copper, and Zinc Retention by Phosphate Rock
TL;DR: In this paper, the solid-liquid interface reaction between phosphate rock (PR) and metals (Pb, Cu, and Zn) was studied, and it was shown that PR can effectively remove Pb from solutions, even in the presence of other heavy metals (e.g. Cu, Zn).

Review of biochar for the management of contaminated soil: Preparation, application and prospect.
TL;DR: To determine the effect of feedstock and preparation conditions such as pyrolysis temperature, retention time, gas flow rate, additives on the biochar characteristics and application potentials, the relevant mechanisms should be adequately considered for maximizing the all-around efficiency of biochar amendments.

Stabilization of heavy metal-contaminated soils by biochar: Challenges and recommendations.
TL;DR: In this review, the negative effects and challenges of applying biochar for the remediation of HM-contaminated soils are thoroughly summarized and discussed, including the changeable characteristics of biochar, biochar over-application, toxic substances inBiochar, activation of some HMs in soils by bio char, nonspecific adsorption, and the negative influences of bio char on soil microorganisms and plants.

Biochar: A Sustainable Approach for Improving Plant Growth and Soil Properties
TL;DR: In this paper, the properties of biochar, its interaction with soil microflora, and its role in plant growth promotion when added to the soil are discussed. But, it has been widely documented in previous studies that, the crop growth and yield can be increased by using biochar.
