Area of Science:

  • Environmental Science
  • Environmental Chemistry
  • Bioremediation

Background:

  • Nitro-explosives such as Trinitrotoluene (TNT), Royal Demolition Explosive (RDX), and High Melting Explosive (HMX) are widely produced and used.
  • These explosives and their byproducts pose significant environmental toxicity risks, including methaemoglobinaemia and organ damage.
  • Effective removal and degradation from soil and water are crucial due to their persistence and widespread contamination.

Purpose of the Study:

  • To consolidate existing knowledge on the degradation pathways of major nitro-explosives.
  • To identify knowledge gaps and propose comprehensive degradation schemes for environmental remediation.
  • To present an overview of current research, future prospects, and the authors' contributions in nitro-explosive degradation.

Main Methods:

  • Review of published literature on aerobic and anaerobic degradation of TNT, RDX, and HMX.
  • Analysis of environmental transformation products and their toxicity.
  • Exploration of phytoremediation strategies involving plant-microbe systems.

Main Results:

  • Degradation studies for TNT and RDX under aerobic and anaerobic conditions are documented.
  • Anaerobic or anoxic degradation pathways are primarily described for HMX.
  • Plant-based remediation approaches are emerging as a promising strategy for nitro-explosive removal.

Conclusions:

  • Information on nitro-explosive degradation is fragmented, necessitating integrated schemes for effective environmental management.
  • Further research is needed to fill knowledge gaps and develop scalable remediation technologies.
  • A holistic approach combining various degradation methods, including phytoremediation, is essential for mitigating nitro-explosive pollution.
