Most of the time these synthetic auxins are quite safe, but with high air temperatures, say over 85 to 90 degrees, they can volatilize into a gas. The 2,4-D volatilized vapor rises into the air ...

They also volatilize and become air pollution, wash away in rains, and leach through the soil to contaminate the water stream. They damage microorganisms in the soil when they stay put.

In the lower-temperature range (300°F to 400°F), the oils in a dab will boil (i.e., volatilize). In this phase, the molecules are essentially unchanged and transformed into a vapor state.

According to the extensive work on trichome anatomy done by Kim and Mahlberg, they hypothesized that little striae help volatilize terpenoid compounds into the atmosphere.
