Oxygen-Carrying Biochar Locked Down Cadmium in Flooded Soil
A greenhouse study used oxygen nanobubbles to keep rice-root soil more oxidizing and shift cadmium into less mobile forms.
Summary
A greenhouse study used oxygen nanobubbles to keep rice-root soil more oxidizing and shift cadmium into less mobile forms.
Researchers report that oxygen-nanobubble-loaded biochar released oxygen around rice roots in flooded soil, maintained more oxidizing conditions and converted mobile cadmium into more stable fractions. Treated greenhouse plants accumulated less cadmium in roots and shoots while microbial and growth measures improved. The experiment is not yet proof of durable, field-scale remediation.
Why it matters
