Fireworks – bad or not?

The perky headline on this CBC piece saying that fireworks aren’t that bad for Montreal’s air quality is swiftly contradicted in the second paragraph: “pollutants released by the explosives tended to drift into nearby neighbourhoods where they reach harmful levels.”

In addition, an expert is quoted saying “fireworks displays are a tradeoff between the economic benefit they bring and the not insignificant air pollution they cause.” But that’s just a microcosm of every polluting industry everywhere.
