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.
