Abstract

  1. Triacetone triperoxide (TATP) and hexamethylene triperoxide diamine (HMTD) are prominent explosive threats. Mitigation of peroxide explosives is a priority among the law enforcement community, with canine (K9) units being trained to recognise the scent of peroxide explosives. Herein, the metabolism, blood distribution, and toxicity of peroxide explosives are investigated.

  2. HMTD metabolism studies in liver microsomes identified two potential metabolites, tetramethylene diperoxide diamine alcohol aldehyde (TMDDAA) and tetramethylene peroxide diamine dialcohol dialdehyde (TMPDDD).

  3. Blood stability studies in dogs and humans showed that HMTD was rapidly degraded, whereas TATP remained for at least one week.

  4. Toxicity studies in dog and human hepatocytes indicated minimum cell death for both TATP and HMTD.
