Biochar and heavy metals

Popis výsledku v původním jazyce

Biochars have proven abilities to retard the leaching of heavy metal(loid)s from contaminated soils to which they are added and, as such, have also been utilized to restrict the uptake of metal(loid)s to plants. Two main mechanisms make this possible: (1) direct adsorption and precipitation processes of metal(loid)s onto biochars’ vast external and internal surfaces; and (2) indirect effects on soils to which biochars are added, primarily by increasing soil pH. In general, cations respond more favorably to these effects than anions; consensus exists that biochars are effective at immobilizing metals such as Cu, Pb, and Zn, but can mobilize metal(loid)s such as As and Sb. This chapter draws together evidence primarily from laboratory and greenhouse studies confirming these effects, while field evidence is more limited. Case studies are presented to highlight the efficacy, or otherwise, of biochars for the immobilization of metal(loid)s in soils and corresponding impacts to plants, whereafter options for optimal biochar deployment are discussed.
