| Zusammenfassung |
| Anthropogenic activities are resulting in an increase of the use and
extraction of heavy metals. Heavy metals cannot be degraded and hence
accumulate in the environment, having the potential to contaminate the food
chain. This pollution threatens soil quality, plant survival and human
health. The remediation of heavy metals deserves attention, but it is
impaired by the cost of these processes. Phytoremediation and biochar are
two sound environmental technologies which could be at the forefront to
mitigate soil pollution. This review provides an overview of the state of
the art of the scientific research on phytoremediation and biochar
application to remediate heavy-metal-contaminated soils. Research to date
has attempted only in a limited number of occasions to combine both
techniques, however we discuss the potential advantages of combining both,
and the potential mechanisms involved in the interaction between
phytoremediators and biochar. We identified specific research needs to
ensure a sustainable use of phytoremediation and biochar as remediation
tools. |
