XRF readings:
Lead: 9100 ppm · Cadmium: 0 ppm · Arsenic: 783 ppm
Verdict: High: FluoroSpec test required
This Washington State rubberized magnet: 9,100 ppm Lead. 90 ppm (& up) is unsafe for kids. Magnets are not considered to be children’s items. tested at 9100 ppm lead, significantly elevated. The bioavailability question (can this lead reach a person?) depends on whether the lead is locked into a fired matrix or sitting on a painted surface. Arsenic reads 783 ppm, worth noting on top of the lead question.
What this XRF reading actually means →
XRF measures lead presence on the surface. It does not measure whether that lead can reach a person. That distinction matters for how you should react to this number. Read the full primer.
