Might aswell ban fireworks altogether! These annoying 'Health and Safety' killjoys.
What about the nitrogen oxides, sulpur oxides, polycyclic aromatic hydrocarbon (PAH's) being pumped out of automobile exhausts on a DAILY basis? Hang your head out of the car window on the M25 and take a deep breath- you see what I mean (cough, cough, cough).
Much of pyrotechnic smoke consists of metal particulates (oxides and sulphides) which eventually settle to the ground and become absorbed harmlessly into the soil and vegetation. The concentration of these particulates dispersed over a wide area must be very small indeed- neglible.
Actually my purpose is not to show fireworks in a bad light, but to refute this seemingly ridiculous statement regarding an industrial furnace that burns up to half a million tonnes of unclassified domestic waste, containing God knows what, a year. Central government seems hell bent on building hundreds of these things to burn waste that could well be composted or otherwise benignly decomposed. Their defence of the health worries is to trot out this assertion vis a vis the millennium display which, to my mind. makes no sense at all. I would like a manufacturer of fireworks to give quotable evidence that the allegation is nonsense so that those of us having incinerators (euphemistically called energy from waste) forced upon their localities can shoot down the daft statements like this and the one that garden barbeques are more polluting than incinerators.
