XRF readings:
Lead: 2953 ppm · Cadmium: 59 ppm · Arsenic: 344 ppm
Verdict: Elevated: keep away from children regardless
This 1984 Vintage Fisher Price Little People Yellow School Bus: 2,953 ppm Lead + 344 ppm Arsenic. Did you have this one? tested at 2953 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 344 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.
