Those are lead COMPOUNDS.
NOT metalic lead.
There is a huge difference in the behavior of metal compounds and pure metals.
You will NOT absorb metalic lead through your skin, nor get lead poisoning from eating lead shot.
We leave lead bullets in people all the time, and outside of synovial fluid in joints that MAY attack lead, they just sits there and do nothing.
If you touch lead and get some on your skin and THEN manage to ingest it you can absorb some.
The lead is finely divided and has a very large surface area.
