I think that the mining in Canada has recently stopped.
I realize I'm being extra cautious but hopefully our restorations don't go directly to a landfill after they leave our hands. Since the health effects don't show up for several decades if the only people exposed are in there sixties or later it probably doesn't matter. I aware of the case of lead for instance. Electronics for sale to countries in the European Union cannot contain lead (and some other things), that's the RoHS thing. I don't like using lead-free solder at all. It melts at a higher temperature and even then doesn't flow like the leaded solder. If you buy a lead acid battery in the US now, the cost includes a recycling fee, $3 I think. Perhaps in the future it will be illegal to sell anything containing asbestos or perhaps a fee would be involved. There are materials like fiberglass, ceramics and even some plastics that can replace asbestos.
