Oh dear God. What garbage clickbait.
NO ONE is adding heavy metals to spices, certainly not on purpose. May there be residues from soil? Heavy metals are part of nature also. OK - what form are they? Are they non-toxic organic forms? What's the total content? What limits have regulatory authorities like FDA have?

CR tested 126 products from McCormick, Trader Joe's, Whole Foods, and other popular brands. Almost a third had heavy metal levels high enough to raise health concerns.
Do you know where most spices are grown? The Middle East. A place where they wipe their butts with their left hand.
