XRF readings:
Lead: 4 ppm · Cadmium: 0 ppm · Arsenic: 0 ppm
Verdict: Low: probably not a concern
This Natural Chelation: Food-Based Interventions & Why I (Personally) Don’t use Supplements (Also: Can you remove Lead from the body?) reads 4 ppm lead, below the 90 ppm CPSC threshold for children's products and within the typical XRF noise floor for trace contamination.
