Looks like chocolate is a known source of heavy metals. Here's just one study I found in Google Scholar: https://www.sciencedirect.com/science/article/abs/pii/

  So the raw beans have heavy metals? Or does the processing introduce them?

    From the OP article, some metals are exclusively from the beans (cadmium), others are introduced later (lead). But yeah, every time you're eating plant material, there will be some trace level of heavy metal. And it just increases up the food chain. Bioaccumulation is pretty cool as a phenomenon

    The article says that cadmium is in the beans (because it is in the soil). But lead is likely introduced in processing.
