Fireworks pollute air, study says

News flash: lighting tons of stuff on fire and hurling it high in to the open air may actually cause air pollution.  Read about it here and here.  This ground-breaking study appeared in the journal Atmospheric Environment and was authored by totally actual real scientist Dian Seidel.

I'm guessing Dian Seidel is not a rocket scientist, because using a rocket would probably cause pollution too.
