Which is a clever way to say 'I don't really know.'

Fireworks emissions are mostly residue of carbon and sulphur; 2 moderately heavy elements that don't distribute far into the atmosphere. They settle out quickly and are not harmful per se, unless were talking stupid large levels. To my knowledge, there are minimal hydrocarbon combustibles to break down into lighter gases.

Vehicles of course, combust. And they are everywhere all the time, creating large total amounts of pollution. Some smaller sources of polluting releases don't have a very large overall volume to deal with, so they don't merit regulation (or have been overlooked). In these comparisons, sources are weighed on their total contribution to the emitted whole.

The stack scrubbers on trucks are a fairly recent addition to their rolling hardware because the carbon releases are quite large when considering all of the trucks out there. And they are everywhere at street level, impacting our immediate breathing opportunities -- not just some esoteric high altitude percentages. In the weighing of individual sources, it's not just how much, but where and when.

I repeat -- this is a stab, so hold the tar and feather pillows.
