Absent strong
acids, metallic lead is comparatively safe.
Yeah. But "Chemistry puzzles me" and I'm not too confident I
won't inadvertently electrolyze some of the lead into solution. Nor
It's possible that you will, but unless you then drink the electrolyte at
the end of the experiment, I don't think it will do you all that much harm.
that the kids won't do so when they try something
clever out.
Heavy-metal poisoning (not just lead, either) is one of those
slow-acting, subtle things where you can get into a lot of trouble
before you realize it. I know it's around a lot (like, the car
The other side to this is that unless you show kids how do fun things,
they will have a go on their own. Possibly with things that are a lot
more dangereous than a car battery and lead.
And unless you show them that there are dangers which can be avoided (and
not just by neer doing <foo)), there is a very real danger they will
assume everything they may coem to try is 'safe' or even if it's not,
there's no 'real danger'. And unfortunately, they are then likely to end
up trying certain illegal substances...
Yes, I solder outside, for improved ventilation, when
I
solder. I'll wear the "paranoia" badge but I may not change my
behavior.
I think that's going a bit far., The fumes given off when soft-soldering
are flux, the amount of lead in them is very small.
I think I've expressed this view before... Everything has some risks
associated with it, even getting out of bed in the morning. So I could
either spend my life lying in bed and die of boredom or I can get on with
what I enjoy, even though there are some dangers in doing so. I'll take
sensible precaustions (not drinking the electrolyte as it may contain
heavy metal ions, not eating solder, making sure high voltage devices are
isolated and discharged before I work on them, etc). My life will
probably be shorter doing that, but it will be a lot more enjoyable which
would seem to be the important thing.
