tin and lead is a stable compound. I'm not sure that's correct. Tin and lead can form an alloy in any proportion. A compound has a specific ratio of elements. An alloy does not. |

Car batteries which are allegedly recycled in accordance with the WEEE directive; end up in a big pile in India, which is set alight and street urchins (usually barefoot) shovel the molten lead into wheelbarrows as it runs out the bottom of the pile. I find this hard to believe. I don’t having seen how they dispose of full dead ships. Absolutely ****ing bizarre, like something out of hell. A charged lead-acid battery contains plates of both elemental lead and some oxidized form of lead. Burning the battery would presumably release only the former, a waste of the latter. Presumably they do something more once the fire has gone out. http://en.wikipedia.org/wiki/Lead-acid_battery A discharged battery contains less elemental lead and more oxidized lead. Burning it will not reduce the oxidized lead to elemental lead. Auto batteries have been recycled in the US for decades. The cell construction of a car battery makes recycling relatively straightforward. Burning the battery is just plain stupid. But very cheap and easy to do. http://en.wikipedia.org/wiki/Automot...tery_recycling Note the remark about the sometimes-high value of lead-acid batteries. In short, I think this story is phony-baloney. I don’t after having seen the doco on how they deal with dead ships. Nothing like how its done in the west. |

Burning the battery is just plain stupid. Unfortunately the slum dwellers in India never got around to installing a state-of-the-art metal-reclamation plant. True. But the point is that there seems to be no point in doing a botched, inefficient job of reclaiming battery lead. There is when there is no possibility of having the metal reclamation plant. |

The main argument against the lead acetate line is that the kids didn't drink much wine and would have been a lot more affected by the lead plumbing and the effect of lead is much more pronounced in kids for various reasons. |

And like I said, the pipes claim is more plausible with kids. It's a nice theory, but that's all it is. Yes, but it was the reason for the move to lead free pewter. Empires decline for many reasons. Yep, and in the case of both the roman and british empires, there are other much more plausible reasons for the empire's decline. I think about the only certainty is that they always do. Well, it would be more accurate to say that none last forever. Tho china did manage much longer than most. Lead acetate may have played some small contributory part in the process, but the decline of the Roman Empire is pretty well documented, and there were far more significant reasons for it. And there is no reason why the decline can't have been due to a combination of all of the more plausible possibilitys too. Maybe that's what happened to the british empire too ? The British Empire declined for various 'modern' reasons, Its far from clear that many of them weren't part of why the roman empire declined too, tho there was much less of the move away to a different physical location of the center of power seen with the decline of the roman empire. No real equivalent of the barbarians seen in roman times, tho some might claim that moslems are just that. Pretty hard to sustain that claim tho. not the least of which were countries figuring that they could manage their affairs and positions on the world stage, better than was being done for them by us. There was plenty of that with the romans too. They romans werent bankrupted by two world wars with a great depression between them tho. This made them lobby for regaining their independence, and for the most part, we willingly gave them it back. That last was mostly once it became clear that trying to stop them leaving was never going to work, with both empires. We never did see the british empire just give up on the worst of the barbarians and just wall them off and make an obscene gesture in their general direction like the romans did with those hairy legged barbarians in dresses to your north tho. As I'm sure that anyone with an interest in world affairs will attest to, the results for some of those countries, have been less than inspiring. Yeah, specially in africa. Some of the denizens of the white ones particularly would claim that they left the old dart for dead tho. As to whether lead water pipes caused a problem here, I come from a generation that grew up in post-war council houses fed with lead pipes, That certainly explains a lot. and I can assure you that the overall intelligence level in kids back then, was a great deal higher than it is now ...

The story is that over time, this will react with the lead in the pewter, causing it to be ingested. This is altogether different from running pH neutral water through pure lead pipes. There isnt much piped water that is in fact pH neutral. Tends to be more alkaline than beer tho, particularly in britain. And we have also seen a move away from the use of lead in coloring used in cooking vessels and other stuff like drinking mugs too. Very sensibly given the perfectly viable alternatives. The whole 'lead in the environment' argument makes little sense, apart from in a few special cases like lead in gasoline and paint. No argument there.

for drinking, the froggies are fairly lax on that even in the present day. In Francophone countries, children generally drink wine at an early age -- diluted with water. See, for example, the dinner scene at the end of the original "The Fly". Adult Greeks commonly cut wine with water, apparently to reduce the chance of intoxication. |

That's only part of it. It's supposedly true that rain (and other solvents) leech lead from electronic equipment, and it winds up in drinking water. Therein lies an example of why we have the RoHS BS. But lead was mined out of the ground in the first place! But not much of the drinking water comes from where its mined. Not that I think it makes any sense at all to ban lead in solder. Much drinking water in the UK was, and continues to be, supplied via lead pipes, and not all areas have 'hard' water supplies that coat the inside of those pipes with a 'protective' limescale layer. Yebbut, some have blamed the decline of the roman empire on their use of lead plumbing pipes. I think the theory was more to do with them using lead acetate (sugar of lead) to sweeten their wine than of lead pipes to deliver water. It was both. And like I said, the pipes claim is more plausible with kids. I seriously doubt the Romans had a minimum age limit for drinking, Me too, but I doubt too many of the kids drank anything like as much of it as the adults did for various reasons. the froggies are fairly lax on that even in the present day. Yes, but again, they don't drink anything like as much of it as the adults do. |

In Francophone countries, children generally drink wine at an early age -- diluted with water. That was pretty common in Britain at one time too. And still happens with beer, shandys etc. See, for example, the dinner scene at the end of the original "The Fly". Adult Greeks commonly cut wine with water, apparently to reduce the chance of intoxication. The minimum legal age in the UK (including Scotland?) for children to consume alcohol is 5. The 18-year-old restriction is for purchasing and consumption in pubs, off licences, etc. ISTR that 14-year-olds can consume alcohol with food in restaurants. There is no minimum legal age in australia. Again, the legal restriction is on purchase, not consumption. |

Rod Speed wrote They haven't starved in India for almost half a century now. Then why do they continue to work with obviously unsafe materials, under unsafe conditions, for about $2.40 or $5.80 per day (depending on which article below you trust)? Because the living standards are MUCH lower than in the west. And there is no nice tidy $/day either, the income at that level depends a hell of a lot on luck on the day etc. If there were alternatives to this kind of work, why is the work still being done? Because there are no alternatives for many of them. That's an entirely separate matter to whether they would actually starve to death if they werent allowed to collect the lead from batterys burnt on piles of batterys. India and most of the 3rd world countries have come a long way in education and information distribution in the last 20 years. Irrelevant to that particular question of how many of them starve to death today. It's highly likely they would have seen the news reports on the internet, read them in the papers, or heard rumors of their inevitable demise from lead poisoning. Those street urchins arent even literate. Yet, they continue to work with the stuff. They continue to run around in the traffic begging from the cars that have to stop temporarily too. While there might be other reasons, I suspect that lack of alternative work might be the major reason. Separate matter entirely to how many of them actually starve to death today. "Ship breaking business a big hit this year" $5.80/day That number is straight from someone's arse, we can tell from the smell. http://www.instantnews.net/ship-brea...this-year.aspx Incidentally, the article has an error. India does not have a minimum wage. Its also no news that shipbreaking has been big business in India for decades now. "India's Shipbreakers Risk Death at $2.40 a Day as Economy Booms" http://www.bloomberg.com/apps/news?pid=newsarchive&sid=ao0a9tcrA_0A That number is straight from someone's arse, we can tell from the smell. |
