I just want to point out that usually IKP/GaBi allocates the impact of mining by value not mass thus putting the vast majority of the burden for mining on valuable materials. I suspect that this is true in this analysis as well. Notice that in most of the graphs the majority of the impacts are due to silver, even though silver is around 3% by mass of the composition of most solders. I suspect the conclusions would be different if the allocation of impacts were by mass rather than the value of the materials being mined. I'll leave it up to the group to debate which method of allocation most accurately assigns environmental impact of mining to an element.

(Thanks, Peter). I was overwhelmed by the number of members asking for the German version, so I shudder at the thought of having to do the same for the English version with my present disability. I have therefore placed the doc on the web at http://www.protonique.com/download/ where interested parties can download it freely (PDF file, 3.4 Mb). Please note that opening the file will produce a small hiccup about half way through. Just ignore it and carry on and it will continue normally. As I have had to re-subscribe, I'll lurk here to see reactions, but it is unlikely I'll post unless there is something that REALLY needs me! I should like to thank all who have enquired after me and apologise for not having replied. My problem makes it hard, but not impossible (as you can see), to respond. I'll give an update of the situation. On Monday, two weeks ago, I suffered a minor stroke which affected my RH side and especially my right hand which was totally paralysed. This hand, which behaved like a slab of wet fish, was useless for either keyboard or mouse control. I've been lucky and now have recovered 90% of movements (with conscious effort), 50% of strength (least in index finger and thumb) and 20% of agility, so I can now do most everyday things, albeit perhaps slowly. Computer use is still a big effort, though. Hopefully, I will improve further, with time and patience. I'm still undergoing tests (CT scan revealed minor ischaemic problems and other normal signs of aging: MRI scan not possible because of my pacemaker: blood chemistry is fine: will have carotid doppler and possibly angiogram tests next week). Preliminary Dx and prognosis is encouraging so you may have to put up with me for some time yet, even if not in the immediate future. I request no correspondence on personal matters, please! Good bedtime reading of the presentation! Best regards, Brian
