The cadmium could easily be tied to pigments, though I suspect this is more likely from environmental contamination. Some quick google searches find things like: https://www.betterhealth.vic.gov.au/health/HealthyLiving/cadmium https://www.betterhealth.vic.gov.au/health/HealthyLiving/cad... https://www.atsdr.cdc.gov/csem/csem.asp?csem=6&po=5 https://www.atsdr.cdc.gov/csem/csem.asp?csem=6&po=5 https://www.tandfonline.com/doi/pdf/10.3184/095422910X12631439471494 https://www.tandfonline.com/doi/pdf/10.3184/095422910X126314... So likely, they aren't using the Cadmium and Lead for anything directly with these products, it just happens to be around as a contaminant from other processes.
