when they tried to pass the taggant for explosives and found that the most common explosive was ammonium nitrate and it is also used by farmers and
used on lawns and other agriculture. This would have caused so much cross contamination that the taggants would have been useless within a short
period of time.
it would be a major problem at a outdoor bombing site if the lawn had been fertilized with AN.
or for a building bomb concrete made with rock from a quarry where they blasted with explosives.
or along a highway where trucks loaded with hay pass through.
There also is a problem with chemical taggants getting into the food supply where they might cause health problems
Another taggant they talked about was nanoparticles of metals like aluminum oxide.
Boy were these people nuts. aluminum particals+ammonium nitrate+ water is a common blasting agent. and they wanted to mix the aluminum with farm type
fertilizer making farmers use aluminized slurry explosives on there fields.
