Seeing as I started it Gerhard .... Now, if I can find this in 10 minutes with Google, why couldn't the author of that page, who seems way more interested and passionate about this than I am, do the same to prove his case? If someone says to me "The sky's falling !!!", I'd say "Show me" I just know that Chris Conway has made more of a mess with his car and camp fires than I ever have with fireworks But this isn't entirely about that particular page. It's about all lazy, emotional people who regurgitate poor information and half-truths Anyhoo http://en.wikipedia.org/wiki/Fireworks "Pollution" paragraph at bottom of page. Effects of fireworks, according to wiki, are debatable You could quantify the effects. Amount of chemicals burned, combustion products, prevailing winds, rainfall, volume of atmospheric air combustion products disperse into, etc etc http://www.nsca.org.uk/pages/environment_facts/firework_effects.cfm "Current research indicates that deposits of pollutants from fireworks do not pose a risk to soil or water" Mission Statement NSCA brings together organisations across the public, private and voluntary sectors to promote a balanced and innovative approach to understanding and solving environmental problems. NSCA is both active and influential in the fields of air quality, noise, land quality, and industrial regulation. We are a registered charity with over 100 years experience of environmental campaigning, public information provision, producing educational resources and policy formulation This appears to me a sensible, balanced approach. Basically saying, yes, fireworks are pollutants, and people who have a problem with combustion products need to be aware of that and no, they aren't the biggest polluting evil in society http://deseretnews.com/dn/view/0,1249,595076027,00.html -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
