I suspect that the largest producer of fireworks, China, also is the largest consumer of fireworks—by far. It’s surprisingly hard to find the numbers though. Try Googling “fireworks consumption by nation”. Like the BBC, Google seems to think this is a US-led issue. Would like to see the actual numbers if anyone can find them.

Most of the fireworks use stuff that disperses quickly.
It's the BBQ grills that are putting aerosolized greases into the air, the stuff that floats and clings and stays around.
That's where those lovely delicious smells that linger live.

I continue to flag BBC articles on HN due to their low quality and irrelevance to the site.
