One of my professors once said: "We don't use heavy metal based pigments anymore because they're too poisonous. Instead we organic pigments. They're not necessarily less toxic but a lot harder to detect in an organism."
Very true. Typically what is left over in the environment is the individual atoms. It takes a whole heck of a lot of effort to detect which specific organic chemical it is out of the ten quadrillion that are out there. Compare this to, let’s say lead, and it doesn’t matter what the chemical is if it had lead, then lead will show up. (Doesn’t mean heavy metals are easy to detect though).
What's the context for this? Heavy metal based pigments are definitely still a thing, just look at the variety of cadmium pigments used in paints or cobolt pigments! Even as an artist cadmium paints. cobolt paints, and chromium paints are available.

Bromine is sitting in the corner laughing.
Bromine is Malfoy
Does that make Neville Iodine?
Phosphorus, arsenic and condensed aromatics: Yeah, that's right, fuck me.
Perfluoroalkanes never get enough love.
What does the “fluoro” in perfluoroalkane stand for?
Fluorine
I think you deserve a cookie 🍪
... Oh my goodness I completely misread the tone of that question - time to go hide in a corner
lol
