Conclusion
- long term effects still not fully understood
- more attention for the long-term efficiency of RM to
immobilize PTEs is necessary: more field studies!
- properly assess the feasibility and effectiveness of RM in
environmental remediation
- more attention for the bio-availability of PTEs in red-mud
