How can I test for lead in my tumeric?

Edit: found this page which is amazing https://eatrightindia.gov.in/dart/

This page is fascinating! I love the iodized-vs-non salt test by rubbing on potato and then sprinkling lemon juice to see if blue (iodized).

At the same time, it feels so sad this page is necessary.

It doesn't list a test for lead in turmeric powder, unfortunately.
Also, the test for lead looks suspicious to me. The shape of the turmeric laying in the bottom of the glass looks absolutely identical between the two glasses. Like they used the same sample, but added some color to the water for the "adulterated" picture.

Edit: Which I guess is ok, since they're just showing what to look for and they aren't falsifying an actual test.

It's below the turmeric whole test, and is more or less the same test.
That's described as a test for "artificial colour"
The lead is used to adulterate the product for color if I'm recalling correctly.
Lead chromate is an incredibly vivid yellow. Good color, bad health effects, as we learned from years of lead paint.
