Abstract
Some heavy metals are highly toxic and can be stored for long periods in any ecosystem. This is a very sensitive issue because heavy metals can enter the food chain and exert negative effects on human health. This hazard should thus be reduced or eliminated. For that, biochar, a carbon-rich material can be added to soils for adsorbing heavy metals. Here we review the mechanisms of biochar applications on heavy metal adsorption in soil, with focus on feedstock of biochar, pyrolysis conditions, biochar properties, and soil characteristics. Biochar application does not entirely remove heavy metals from the soil environment. Hence biochar-applied metal-contaminated soils should be regularly monitored for heavy metal toxicity since the biochar’s immobilization capacity may decline with time.
