Lead arsenate was used as a pesticide on fruit trees until the 1950's or later, and can still be detected in the soil of former orchards with arsenic typically at concentrations which are unsuitable for residential purposes.

We find it in fancy decorative paints used in old theaters.  It was still used in the 1920s.  And artist's paints used it a lot longer.  Here in NYC in the 1990s, I could tell you who to contact for the pigments if you wanted to buy them.  I assume smart internet users can still get them.
