Vinyl chloride will form some dioxin upon combustion.

When left to break down in the environment, after several days vinyl chloride will break down into a combination of formaldehyde and hydrochloric acid. The latter of which won't be harmful, but the former will be.

Vapor phase formaldehyde breaks down in the air within hours.[1]

It will also be destroyed in the soil by any number of mechanisms, with a half-life of about 14 days. [2]

I do not think combustion of vinyl chloride at atmospheric pressure is going to create much if any dioxin
