Purpose(s): Too many to count on ten fingers. It really depends on where they are going to be used. Many are calming agents. Others induce a state of haziness. Rarely, we were asked to develop mixtures to incite anger/rash behavior. 90% of what we worked on aimed to alter emotions/mood/state of mind.

Toxicity: In almost all cases, it was made very clear to us that what we were working on should have minimal toxicity. Naturally, a small percent of the population will have allergic tendencies to a chemical compound. But in some cases we even went as far as animal testing to ensure that the chemicals we were working on were relatively non-toxic. I never worked on a project where the intended result was toxic/fatal.

Breakdown/Accumulate: Varies a lot based on the chemical structure. Some of the mixtures we developed were intended to dissipate to concentrations as low as one part per billion by the time they reached ground level. Others were specifically designed to reach ground level and last for up to a year. Even after rain/wind/snow, etc.
