XRF readings:
Lead: 1862 ppm · Cadmium: 0 ppm · Arsenic: 1862 ppm
Verdict: Elevated: likely lower risk in fired ceramic, test to confirm
This Red & Yellow Brio Train, Made in Sweden: 1,862 ppm Lead & 575 ppm Arsenic tested at 1862 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 1862 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.
