The lead chromate isn't particularly dangerous.

https://en.wikipedia.org/wiki/Lead(II)_chromate

>Despite containing both lead and hexavalent chromium, lead chromate is not particularly toxic because of its very low solubility. The LD50 for rats is only 5,000 mg/kg. Lead chromate is treated with great care in its manufacture, the main concerns being dust of the chromate precursor. "Extensive epidemiological investigations have given no indication that the practically insoluble lead chromate pigments have any carcinogenic properties".

The tumeric used in medicine are not pristine examples of 100% tumeric.

Well, the reference to its (purported) carcinogenity was edited away twelve days ago: https://en.m.wikipedia.org/wiki/Special:MobileDiff/118137387...

I looked at the source and it's OSHA. You'd do a blood test for lead, but it was due to it being inhaled and causing lung cancer. https://www.osha.gov/laws-regs/federalregister/2006-02-28-0

Ingestion wasn't mentioned, it's main danger is spray paint.

Ah so maybe it's ok to dust crops with lead chromate then. That yellow color really does "pop".

Yes.
