It's not nothing, but 1% goes to show just how much is no5 made by the giant 1 day full of sky explosions, and how likely 70-80% is from transport and energy sector.
Eliminating all fireworks from earth and banning them tomorrow would have a near 0 impact on anything, and be completely erased if a coal plant runs an extra day or two.
Assuming there would be a single source responsible for the remaining 99% of yearly pm10 particulates, let's say a giant coal power plant, then it would take 4 days of it running to have the same impact as fireworks.
Giant ceremonial bonfires /= fireworks, for one. Tons of random shit can go into bonfires beyond just wood, the wood is of incredibly differing quality and chemical treatments, and bonfires by their nature a low to the ground and intended to last for at minimum an hour or they're not worth making.
This is not the same discussion as fireworks. It's also still not long term effects, as the site warns of poor air quality in the days that follow the giant bonfires if there is no wind or weather, but it does dissipate either way, not that this event gives everyone cancer or something.
The question was about fireworks. And yea, fireworks are an afterthought still. Compared to Guy Fawkes Night maybe even more of an afterthought. Guy Fawkes Night and 4th of July still hardly register on the global scale of CO2 and GHG outputs.
I was pointing out that fireworks were being used in a way that lowers the local air pollution for residents, for days, not just the evening. You can say 'barely registered' but I've shown you a clear case of it very much registering in terms of effects on local populous.
I saw a bonfire with a calculated pallet cost of $100k. That's something. Fireworks are a big part of the bonfire celebration and put pollutants into the lower atmosphere. The example I gave is more firecrackers being used at street-level.
