Effects of biochar on availability and plant uptake of heavy metals – A meta-analysis
De Chen,Xiaoyu Liu,Rongjun Bian,Kun Cheng,Xuhui Zhang,Jufeng Zheng,Stephen Joseph,David E. Crowley,Genxing Pan,Lianqing Li +9 more
TL;DR: A meta-analysis of the literature on biochar's effects on heavy metal accumulation in plants in responses to the variation of soil, biochar and plant showed that manure-derived biochar was the most effective for reducing Cd and Pb concentrations in plants as compared to biochars derived from other feedstock.
Journal ArticleDOI
State of the art and future challenges for polycyclic aromatic hydrocarbons is sediments: sources, fate, bioavailability and remediation techniques
TL;DR: Recent studies have shown that a combination of strategies including in situ approaches is likely to provide the most effective long-term solution for dealing with contaminated sediments.

Dynamic molecular structure of plant biomass-derived black carbon (biochar)
TL;DR: A molecular-level assessment of the physical organization and chemical complexity of biomass-derived chars and, specifically, that of aromatic carbon in char structures suggests the existence of four distinct categories of char consisting of a unique mixture of chemical phases and physical states.
