I don't follow your math here, but I do realize that lead's toxicity is a problem. One issue that's not often on our radar is that some lead recycling is carried out overseas in nations with little environmental regulation and/or enforcement. I've read descriptions of old batteries being knocked apart by workers using little or no personal protection, unwanted materials literally thrown on the ground, waste water and electrolyte going right into rivers. Some of this is done out of ignorance, some out of outright carelessness. It's a significant problem, but few here know about it. http://dotearth.blogs.nytimes.com/2013/05/24/old-batteries-crossing-borders- leave-a-toxic-lead-trail http://tinyurl.com/p67wfo7 David Roden - Akron, Ohio, USA EVDL Administrator = = = = = = = = = = = = = = = = = = = = = = = = = = = = = EVDL Information: http://www.evdl.org/help/ = = = = = = = = = = = = = = = = = = = = = = = = = = = = = Note: mail sent to "evpost" and "etpost" addresses will not reach me.
