Lead is used everywhere. Not in paint anymore but you can buy lead weights at hardware stores. Don't grind it up and put it in your muni water supply, but it's a household substance that is harmful if ingested, like many others.

another example, you can still buy lead based solder, even at a local hardware store.

Also lead acid batteries which have ~ 50 lbs of lead sulfide in them (which also releases toxic gas if melted!)

Sulfate, perhaps.

Is lead based solder not standard? (I've never soldered.)

Both lead solder and lead-free solder are commonplace. Lead is standard in aerospace and military applications, while lead-free is standard in most products sold in the EU.

Those are often bismuth weights.
