The banning of lead in solder has necessitated the need for businesses to invest in new, hot-air soldering ovens to heat the lead-free solder to a much higher temperature... This results in greater energy use, generating more carbon emissions rather than less... i.e. fossil fuels are burned to make the electrical energy that runs these processes...
	What are the effects of  mining the raw materials - with what environmental results?
	What happens to the reliability of electronics circuits when the Tin/lead solder is replaced with SAC and other alloys?
	Regarding the use of silver and gold in solder... What effects will the increased amounts of these materials being supplied to the mass market for electronics have?
	The refining of these materials uses poisonous chemicals... such as Hydrogen Cyanide, Sulfur anhydride, Carbon monoxide and Nitrogen oxide, Carbon dust, Ore dust, Non organic Dust and Chlorine vapors (fumes) are released into the atmosphere... with the recent increase in unregulated manufacturing in Africa, Latin America, China, India, and other less regulated countries without proper waste treatment, what will the level of pollutants from industrial waste rise to?
	What affect does the lead free movement have on this?
	What about the levels of these chemicals in our oceans and rivers getting into our imported sea foods?
	Who will the world hold responsible for the results of this legislation?
