There's been a push to eliminate lead solder in electronics in recent years as well, because of the possibility of lead leaching into groundwater from discarded electronics in landfills. In Europe that's known as the "RoHS" initiative and a lot of electronics you buy are labeled with a symbol for it.
Science marches on. We used to think that small concentrations of stuff that couldn't hurt anybody; now we find out that yeah, they actually do do quite a bit of harm. I know environmentalism is a thing of the left but let's be real. We can't treat the planet like a toilet and we can't shove the costs of disposal and cleanup and so forth onto succeeding generations.
I remember when RoHS was beginning to become a thing in the US. Tin whiskers and all of that. Retrofitting workstations, cleanup and all the rest. Ridiculous. There was a report at the time that electronics accounted for 0.00something percent of the lead waste on the US. The largest lead polluter was, and remains today, the auto industry. Orders of magnitude more pollution comes from car batteries than any amount of lead solder, or bullets, for that matter.
